Please read this instruction manual in its entirety before installing, wiring or using this product in any way. Failure to comply with these instructions will invalidate the SunPower Limited Warranty for PV Modules. 1.1 Disclaimer of Liability The installation techniques, handling and use of this product are beyond company control. Therefore, SunPower does not assume responsibility for loss, damage or expense resulting from improper installation, handling or use. 1.2 Underwriters Laboratories (UL) Listing Information This product meets or exceeds the requirements set forth by UL1703 and ULC/ORD-C1703-01 for PV Modules. These Standards cover flat -plate PV modules and panels intended for installation on buildings or those intended to be freestanding. To satisfy the listing for this product the modules must be mounted with a rack or standoff structure. The UL listing does not include integration into a building surface because additional requirements may apply. This product is not intended for use where artificially concentrated sunlight is applied to the module. 1.3 Limited Warranty Module limited warranties are described in full in the SunPower warranty certificates obtainable at www.sunpowercorl).com. In summary, the Limited Warranties do not apply to any of the following; PV modules which in SunPower's absolute judgment have been subjected to: misuse, abuse, neglect or accident; alteration, improper installation, application or removal. Including, but not limited to installation, application or removal by any party other than a SunPower authorized dealer; non -observance of SunPower's installation, users and/or maintenance instruction's;,repairlormodifications by someone other than an approved service technician of SunPower; power failure surges, lightning, flood, fire, accidental breakage or other events outside SunPower's control. 2.0 Safety Precautions Before installing this device, read all safety instructions in this document. Dancleri Module interconnection cables pass direct current (DC) and are sources of voltage when the module is under load and when it is exposed to light. Direct current can arc across gaps and may cause injury or death if improper connection or disconnection is made, or if contact is made with module leads that are frayed or torn. Do not connect or disconnect modules when current from the modules or an external source is present. • Cover all modules in the PV array with an opaque cloth or material before making or breaking electrical connections. If local codes require, insure that PV connectors have a locking feature in order to defend against untrained personnel disconnecting the modules once they have been installed. All installations must be performed in compliance with the National Electrical Code (NEC) and any applicable local codes. Safety and Installation Instructions - Document 001-14158 Rev N • There are no user serviceable parts within the module. Do not attempt to repair any part of the module. • Installation should be performed only by authorized personnel. • Remove all metallic jewelry prior to installing this product to reduce the chance of accidental exposure to live circuits. • Use insulated tools to reduce your risk of electric shock. • Do not stand on, drop, scratch, or allow objects to fall on modules. • If the front glass is broken, or the back sheet is torn, contact with any module surface or module frame can cause electric shock. • Broken j-boxes and/or broken connectors are electrical hazards as well as laceration hazards. The dealer or installers should remove the module from the array and contact the supplier for disposal instructions. • Do not install or handle the modules when they are wet or during periods of high wind. • Contact your module supplier if maintenance is necessary. • Suggested cable minimum bend -radius. We advise a conservative bend of equal to or greater than a 40mm (1.5") radius or 80mm (Y) diameter for the smallest module cable bend -radius. • Save these instructions! 3.0 Electrical Characteristics The module electrical ratings are within 10% of UL's measured values under Standard Test Conditions (STC) of 1 kW/m2 irradiance with Air Mass of 1.5 solar -spectral -irradiance -distribution and a cell temperature of 250 C. The electrical characteristics of SunPower modules are listed in Figure 2 of the appendix. If an installation involves a SunPower module which does not appear on this list please consult the product label on the back of the module or visit www.Suni)owercorp.com for the product datasheet. Bypass diodes for each module are rated and factory installed in the modules. The component diodes are not considered user replaceable in the field once installed. The diode configuration for 96 cell modules is 2 diodes for 2 strings of 24 cells in series, plus one diode for a single string of 48 cells in series. For 128 cell modules, the configuration is 2 diodes installed for 2 strings of 32 cell in series, plus one diode for a single string of 64 cells in series. The diodes are one of the following ratings; 1. Schottky type, I5A, 45 PIV (Peak Inverse Voltage) for 96 cell modules. 2. Schottky type, 20A, 45 PIV (Peak Inverse Voltage) for 128 cell modules. 3. Schottky type,20A, 100 PIV (Peak Inverse Voltage) for 96 and 128 cell modules. A photovoltaic module may produce more current and/or voltage than reported at STC. Sunny, cool weather and reflection from snow or water can increase current and power output. Therefore, the values of Is, marked on the module should be multiplied by a factor of 1.25 when determining component ampacity ratings to comply with NEC, Article 690.8(A). An additional 1.25 multiplier may be required by the NEC for sizing fuses and conductors as described in NEC Section 690-8(B). The series fuse must have an interrupting rating that is equal to or greater than the maximum fault current the fuse is required to interrupt, including contributions from all connected sources or energy. The maximum module string open circuit voltage (V,,) shall be calculated as the sum of the rated open -circuit voltage of the series -connected photovoltaic modules corrected for the lowest expected ambient temperature (NEC 2008, Article 690.7). One source for statistically valid, lowest -expected, ambient temperature design data for various locations is the Extreme Annual Mean Minimum Design Dry Bulb Temperature found it the ASHRAE Handbook — Fundamentals. These temperature data can be used to calculate maximum voltage using the manufacturer's temperature coefficients relative to the rating temperature of 25°C (NEC 2011, Article note to 690.7). SunPower recommends the use of open -circuit voltage temperature coefficients listed in Figure 2 of the appendix, when determining Maximum System Voltage. For modules rated higher than 600V DC System Voltage, refer to NEC Article 100, Part II for appropriate series fuse ratings. 3.1 Fire Rating The module is Class C fire rated. ©March 2013 SunPower Corporation.

V 4.0 Electrical Connections Modules may be connected in series and/or parallel to achieve the desired electrical output as long as certain conditions are met. Please use only the same type of modules in a combined source circuit. SunPower modules ship with locking connectors or safety clip, which once connected requires the use of a tool to disconnect module -to -module connections. This defends against untrained personnel disconnecting the modules when under load (which may cause injury or death as stated in Section 2.0) and complies with the NEC 2008 code for safety with PV connectors. 4.1 Equipment Grounding To reduce the possibility of electrical shock, ground the frame of the module or array before wiring the circuit using a grounding method that meets NEC requirements for grounding solar electrical systems. In order to install in accordance with the UL listing of this product, SunPower modules shall be grounded using grounding hardware that has been certified to meet requirements for grounding systems in UL467, UL1703, or UL1741 on anodized aluminum frames. SunPower recommends using 1 of the following five methods of grounding the module frame. In addition, avoid corrosion due to the use of dissimilar metals (we suggest stainless steel between copper and aluminum). 1) Attach a ground conductor to a grounding lay -in lug mounted at one of the four designated 0.17" grounding holes on the module frame. Alternatively, any unused mounting hole can be used to mount the lug. Use a grounding lug such as llsco GBL-4DBT, Burndy CL50-DB- T or Tyco Solklip 1954381-2, and stainless steel hardware (bolt, washers, and nut). A star washer should be used between the grounding lug and the module frame in order to break through the anodizing and establish electrical contact with the aluminum. The assembly must end with a nut and be torqued between 20 inch -pound to 25 inch -pound for a #10-32 bolt. A lock washer or other locking mechanism is needed to maintain tension between the bolt and the assembly. The copper conductor must be attached to the ground lug using the stainless steel set screw provided by the manufacturer. Please refer to NEC Article 690 on grounding PV arrays for specific requirements. 2) SunPower systems may also be grounded through the use of SunPower supplied "IFF clips" which are UL Listed (1703 and 1741). A minimum torque of 10 in-Ibs is required for grounding, however higher torque values will be required to ensure structural integrity. General torque values are 35 to 45 in-Ibs for a 1/4-20 or M6 bolt, but may be higher in specific applications. When using these clips, the array frame (racking) must be grounded in accordance with NEC Article 250. To ensure system safety and structural integrity, strict adherence to application -specific SunPower documentation is required. 3) The SunPower PV Grounding Clip may also be used only in applications where the modules are attached to a SunPower torque tube, #111380. This device consists of Rail Clip #1505-994, Retainer Bar #1504-979, Carriage Bolt (2) #1506-224, Nut (2) #1503-098, Lock Washer (2) #1503-099. Hardware must be torque to 120 in-Ibs. The PV Grounding Clip has been evaluated for bonding to the Torque Tube for use with an over -current protective device rated 20 Amps maximum and a circuit capacity of 600 V, 5000 Amps. *Note: Methods 4-5 were evaluated to UL 1703 by ETL. As such, the use of these devices is not considered part of the UL Listing of these modules. 4) Sunpower modules may also be grounded through the use of an ETL Listed PV Attach Grounding washer #1508-666, which may be used only in applications where the modules are attached to a Sunpower Saddle #1508-738 or #1508-741 using a 1/4 inch rivet. 5) If the Unirac Solarmount system is used for mounting the modules, grounding is achieved using either the Wiley Electronics WEEB UMC or UGC-1 grounding clips in combination with UniRac's Mid or End clamps and 1/4-20 bolt and flanged nut, torqued to 120 in-Ibs. If the Solarmount-I system is used grounding is achieved with the UniRac UGC-2 grounding clips in combination with UniRac's Mid or End clamps and Sliders with a 1/4-20 bolt and flanged nut torqued to 120 in-Ibs. When using methods 2, 3, 4 or 5 the array frame (racking) SUNPOWER CORPORATION Safety and Installation Instructions - Document 001-14158 Rev N must be grounded in accordance with NEC Article 250. To ensure system safety and structural integrity, strict adherence to application - specific SunPower documentation is required. 4.2 System Grounding • Review the following tables for the proper grounding techniques to use for the installation of your SunPower PV system.

Do not exceed the maximum system voltage shown in Figure 2. 4.4 Parallel Connection The modules may be combined in parallel to produce the desired current output. Each series string or module may be required to be fused prior to combining with other strings. Figure 2 describes the maximum fuse size allowed (number of modules which can be connected in parallel and protected by one fuse). Please refer to the NEC Article 690 for additional fusing requirements. 5.0 Module Mounting The SunPower Limited Warranty for PV Modules is contingent upon modules being mounted in accordance with the requirements described in this section. 5.1 Site Considerations SunPower modules should be mounted in locations that meet the following requirements: ©March 2013 SunPower Corporation. All rights reserved. Specifications included in this manual are subject to change without notice. ff SUNPOWER CORPORATION Operating Temperature: All SunPower modules must be mounted in environments that ensure SunPower modules will operate within the following maximum and minimum operating temperatures: Maximum Operating Temperature +85' Celsius, +185' Fahrenheit Minimum Operating Temperature -40' Celsius, -40' Fahrenheit Care should be taken to provide adequate ventilation behind the modules, especially in hot environments. Design Strength: SunPower modules are designed to meet a maximum positive (or upward, e.g. wind) and negative (or downward, e.g. static load) design pressure of 2400 Pa (Pascals; 245 kg/m2) when mounted in all of the mounting configurations specified in Section 5.2. Design strength of 2400 Pa corresponds approximately to a wind speed of 130 km/h (approximately t80013a, per IEC reference) with a safety factor of 3 for gusty winds. NOTE: any racking application must have a separate rating per the racking or mounting system utilized by the module/array installer. This mounting system must meet or exceed the certification levels of the installation jurisdiction. SunPower modules are also designed to meet a maximum negative (or downward, e.g. snow load) of 5400 Pa (Pascals; 550 kg/mZ) only when mounted in adherence to Section 5.2 below. 5400 Pa design strength has been verified by SunPower and TUV. 1) 72 cell modules with dimensions of (1559mm x 798mm) meet 5400 Pa in the following mounting configurations described in Section 5.2 below a. Frame Holes b. Pressure Clamps or Clips c. End Mount 2) 96 cell modules with dimensions of (1559mm x 1046mm) meet 5400 Pa in the following mounting configurations described in Section 5.2 below a. Frame Holes b. Pressure Clamps or Clips 3) 128 cell modules with dimensions of (2067mm x 1046mm) meet 5400 Pa in the following mounting configurations described in Section 5.2 below a. Frame Holes b. Pressure Clamps or Clips When mounting modules in snow prone or high wind environments, special care should be taken to mount the modules in a manner that provides sufficient design strength while meeting local code requirements (mounting system must meet or exceed the certification levels of the installation jurisdiction). Excluded Operating Environments & Reconfiaurations Certain operating environments are not recommended for SunPower modules, and are excluded from the SunPower Limited Warranty of these modules. Request the regional dealer to contact SunPower if there are any unanswered questions concerning the operating environment. When the PV modules are not generating power they must remain in the system grounding mode with which they were installed, or in a floating mode. When the modules are not generating power, the process of disconnecting the installation from its commissioned ground or float then connecting an outside voltage source to the modules, will void the module product warranty. 5.2 Mounting Configurations For a non -integral module, the assembly is to be mounted over a fire resistant roof -covering rated for the application. Modules may be mounted at any angle, from horizontal to vertical. Class C fire rating is maintained at all installation slopes. Select the appropriate orientation to maximize sunlight exposure. Specific information on module dimensions and the location of mounting and grounding holes is shown in (Figures 3, 4, and 5). In order to prevent water from entering the junction box, which could present a safety hazard, modules should be oriented with the junction box in the uppermost position and not be mounted such that the front/top glass Safety and Installation Instructions - Document 001-14158 Rev N faces downward (e.g., on a tracking structure that positions the modules with the junction box facing skyward during sleep mode). Clearance between the module frames and structure or ground is required to prevent wiring damage and allows air to circulate behind the module. For 128 cell modules a minimum of 4 inches of clearance is required, for all other modules a minimum of 1.5 inches is required between the module frame and structure or ground. The module is only UL Listed for use when its factory frame is fully intact. Do not remove or alter the module frame. Creating additional mounting holes may damage the module and reduce the strength of the frame. Modules may be mounted using the following methods only: 1) Frame Holes: Secure the module to the structure using the factory mounting hole pairs. Four 1/4" stainless steel bolts, with nuts, washers, and lock washers are recommended per module tightened to a min. torque of 10 in-Ibs. Refer to Figures 3, 4 and 5 for the module dimensions and hole locations. This method has been certified by a third -party organization according to UL 1703. 2) Pressure Clamps or Clips: Mount the module with the IFF clips on the side frame of the module. The side frames are attached to the longer sides of the module. The centerline of the clips should be between 6"tol5"from the end of each of the side frames. Installers should ensure the clamps are of sufficient strength to allow for the maximum design pressure of the module. The IFF clip hardware should be tightened to a min. of 10 in-Ibs. 3) End Mount: End mounting is the capture mounting of the module's end frame to a supporting rail (The end frames are on the shorter dimensions of the module), using IFF clips tightened to a min. torque of 10 in-Ibs. The end -mounting rail and clips or clamps must be of sufficient strength to allow for the maximum design pressure of the module. Verify this capacity with the mounting system vendor before installation. 4) Center Mount PV Grounding clip: A PV Grounding Clip (as Described above in Section 4.1, item 3) may be used to clamp the bottom flange of the frame at the center of the long sides. Minimum clamping length shall be 6" on top of flange and 4" on bottom. The clamps must be of sufficient strength to allow for the maximum design pressure of the module. Verify this capacity with the mounting system vendor before installation. 5) SunPower specified or SunPower supplied mounting systems: Modules mounted with strict adherence to SunPower documentation, using hardware systems supplied by or specified by SunPower. Mounting hardware should not secure the module by applying direct pressure to the front glass, including frame locations where glass is exposed in "drainage notch" openings. 5.3 Handling of Modules during Installation Do not place modules face -forward in direct contact with abrasive surfaces like roofs, driveways, wooden pallets, railings, stucco walls, etc.... The module front surface glass is sensitive to oils and abrasive surfaces, which may lead to scratches and irregular soiling. Modules that feature antireflective coated glass are prone to visible finger print marks if touched on the front glass surface. SunPower recommends handling modules with anti -reflective glass with gloves or limiting touching of the front surface. Any finger print marks resulting from installation will naturally disappear over time or can be reduced by following the washing guidelines in Section 6.0 below. Product datasheets specify the glass type used by a particular module. 6.0 Maintenance Visually inspect all modules annually for safe electrical connections, sound mechanical connection, and freedom from corrosion. This visual inspection should be performed from ground level, unless performed by trained SunPower dealers or trained SunPower support personnel. Periodic cleaning of modules is recommended, but is not required. Periodic cleaning has resulted in improved performance levels, especially in regions with low levels of annual precipitation (less the 18.25 inches ©March 2013 SunPower Corporation. All rights reserved. Specifications included in this manual are subject to change without notice. it (46.3cm)). Consult your dealer or supplier about recommended cleaning schedules for your area. To clean a module, wash with potable, non -heated, water. Normal water pressure is more than adequate, but pressurized water up to 1500psi may be used. Fingerprints, stains, or accumulations of dirt on the front surface may be removed with standard over-the-counter glass cleaners (e.g. Windex) containing ammonia and or vinegar or with a 3%soap and water solution. If only a few panels: first rinse off area and let soak for a short period of time (5-minutes). Re -wet and use a soft sponge or seamless cloth to wipe glass surface in a circular motion. If a large system; wet Figure 2: Electrical Characteristics* SUNPOWER CORPORATION Safety and Installation Instructions - Document 001-14158 Rev N panels with cleaning solution, allow soaking and follow with high pressure rinse or soft squeegee (sponge or soft rubber). Fingerprints typically can be removed with a soft cloth or sponge and water after wetting. Do not use harsh industrial strength cleaning materials such as scouring powder, steel wool, scrapers, blades, or other sharp instruments to clean the glass surface of the module. Use of such materials or cleaning without consultation will invalidate the product warranty. • Figures 3, 4, and 5 are on the next page. w. a Mass xo p - � aget % hi. �.. .tie A� SPR-X21-345-COM +51-3 1000 345 57.3 6.02 68.20 6.39 20 1000 SPR-X21-345 +51-0 600 SPR-X21-335 +5/-0 335 57.3 5.85 67.88 6.23 20 600 1000 SPR-X21-335-BLK SPR-X20-327-COM +5 /-3 1000 327 57.3 5.71 67.60 6.07 20 1000 SPR-X20-327-BLK +5 / -0 600 SPR-X21-255 +5 / -0 255 42.8 5.95 51.00 6.30 20 600 1000 SPR-X20-250-BLK +5 / -0 250 42.8 5.84 50.93 6.20 20 600 1000 SPR-X21-245 +5 / -0 245 42.8 5.72 1 50.78 6.08 20 1 600 1000 SPR-X19-240-BLK +5 / -0 240 42.8 5.61 50.58 5.98 20 600 1000 SPR-435NE-WHT +/- 5 SPR-E20-435-COM +/- 5 435 72.9 5.97 85.6 6.43 20 1000 1000 SPR-425E-WHT +/- 5 425 1 72.9 5.83 85.6 6.18 20 600 1000 SPR-415E-WHT +/- 5 415 72.9 5.69 85.3 6.09 20 600 1000 SPR-41ONE-WHT +/- 5 SPR-E19-410-COM +/- 5 410 72.9 5.62 85.3 6.01 20 1000 1000 SPR-400E-WHT +/- 5 400 72.9 5.49 1 85.3 5.87 20 600 1000 SPR-390E-WHT +/- 5 1 390 72.9 5.35 85.3 5.72 20 600 1000 SPR-343(J/X)-BLK +5/-3 343 57.3 5.99 68.1 6.37 20 600 1000 SPR-327NE-WHT SPR-E20-327 +5 / 0 600 +5/-3 327 54.7 5.98 64.8 6.46 20 1000 SPR-E20-327-COM +5 /-3 1000 SPR-325NE-WHT +5/-3 325 54.7 5.95 64.8 6.46 20 600 1000 SPR-320E-WHT +5/-3 SPR-E19-320 +5/-0 320 54.7 5.86 64.7 6.24 20 600 1000 SPR-318E-WHT +5/-3 318 54.7 5.82 64.7 6.2 20 600 1000 SPR-315NE-WHT,SPR-315E-WHT +5/-3 SPR-E19-315 +5/-0 315 54.7 5.76 64.6 6.14 20 600 1000 SPR-310NE-WHT,SPR-310E-WHT 600 +5/-3 +5/-3 310 54.7 5.67 64.4 6.05 20 1000 SPR-E19-310-COM 1000 SPR-308E-WHT +5/-3 308 54.7 5.64 64.3 6.02 20 600 1000 SPR-305NE-WHT, SPR-305E-WHT +5/-3 305 54.7 5.58 64.2 5.96 20 600 1000 SPR-300NE-BILK, SPR-300E-WHT +5/-3 300 54.7 5.49 64 5.87 20 600 1000 SPR-300E-BLK SPR-295E-WHT +5/-3 +5/-3 295 54.2 5.45 63.3 5.83 20 600 1000 SPR-E18-295-cOM 1000 SPR-290NE-BLK, SPR-290E-BLK +5/-3 290 53.3 5.45 62.1 5.83 20 600 1000 SPR-290E-WHT SPR-245NE-WHT +5/-3 SPR-E20-245 +5/-0 245 40.5 6.05 48.8 6.43 20 600 1000 SPR-240NE-WHT, SPR-240E-WHT +5/-3 240 40.5 5.93 48.6 6.3 20 600 1000 SPR-238E-WHT +5/-3 238 40.5 5.88 48.5 6.25 20 600 1000 SPR-235NE-WHT, SPR-235E-WHT +5/-3 SPR-E19-235 +5 / -0 235 40.5 5.80 48.4 6.175 20 600 1000 SPR-235E-BLK SPR-230NE-BLK, SPR-230E-BLK +5/-3 230 40.5 5.68 48.2 6.05 20 600 1000 SPR-230E-WHT SPR-225NE-WHT, SPR-225E-WHT +50 225 40.5 5.55 48 5.925 20 600 1000 SPR-225NE-BILK, SPR-225E-BLK SPR-217E-WHT +51-3 217 39.3 5.51 47 5.9 15 600 1000 SPR-215E-WHT +5/-3 215 39.3 5.47 47 5.86 15 600 1000 SPR-214E-BLK +5/-3 214 39.3 5.45 47 5.83 15 NA 1000 SPR-21ON-WHT +5/-3 210 40 5.25 47.7 5.75 15 NA 1000 SPR-20ON-WHT +5/-3 200 40 5.00 47.8 5.4 15 NA 1000 *See Product Rating Label for Maximum System Voltage. ©March 2013 SunPower Corporation.

Title: SunPower Modules and Transformerless SPR-p Inverters Authors: Chris Sommerfeld, Senior Technical Trainer Date: March 27, 2012 Bulletin: E12001 Introduction: SunPower is releasing a new generation of DC PV Modules with unprecedented energy conversion efficiency. This module family can be identified in the model number by the letters "NE". These modules benefit from SunPower's high -efficiency back -contact Maxeon cells and due to advancements in module design and construction, these modules no longer require positive grounding on their DC circuits. This significant change allows these SunPower modules to support ungrounded PV arrays thus paving the way for using Transformerless inverters. Transformerless (TL) inverters have enjoyed great success globally over the past decade. TL inverters have been allowed in the US since 2005. TL inverters have not been popular in the US to date due to lack of awareness as well as product constraints. This document serves as an introduction to TL inverter technology and the line of SPR-p inverters including their operation, benefits, features, as well as design and installation considerations with SunPower modules. Important Note: Thoroughly read and comply with all listed instructions for modules and inverters. SPR-p inverter documentation, including installation manuals and data sheets, will retain the original manufacturers' (Power -One) identification.

No information contained herein should be distributed to any other party without the expressed written permission of SunPower Corporation. Page 1 of 7 19 i _: 1 : Detailed content: SunPower Modules and Transformerless Inverters TL inverters have a fundamentally different internal electrical topology than most conventional inverters. TL inverters have no isolation transformer providing voltage conversion and isolation between DC and AC circuits. All voltage conversation and isolation is done electronically to UL standard 1741. TL inverters require ungrounded PV arrays to operate and provide isolation between the DC and AC sides of the system. Neither the DC positive or negative conductors are bonded to ground within the inverter. There is still always equipment grounding present for modules and all metallic components of the system. SunPower modules have historically been required to be positively grounded to achieve maximum system performance. (The positive current carrying conductor is bonded to ground through the inverter's GFDI fuse.) Through extensive research and testing, SunPower has developed a line of modules which can be either positively grounded or left ungrounded. These modules are all identified by "NE" in their part numbers. Modules without "NE" in their part numbers must be positivity grounded to ensure maximum performance. Only modules with "NE" in their part number can be used in ungrounded systems with TL inverters. No other SunPower modules can be used with TL inverters. SunPower's TL inverter partner in the USA is Power -One. The inverters are sold with SunPower branding on their chassis but retain the same Power -One internal components and serial numbers. The inverters have SPR-XXXXp part numbers but rely on Power -One supplied documentation for permitting and other administrative functions. Refer to the Power- One/SunPower equivalency letter.

On average 1% more efficient than inverters with isolation transformers. This means more kilo -Watt hours overtime. • Wide. DC input voltage window. (90-530 VDC depending on model) Design flexibility with smaller string sizes with SunPower modules. Note that to achieve a start up voltage below 200VDC, the inverter must be programmed after it has been installed to minimum start up voltage of 120VDC. • Dual maximum power point trackers. Allows for two different orientations and different series string sizes connected to one inverter. • NEMA 4X. Robust enclosure • Natural Convection Cooling. High temperature tolerance before de -rating. • Light Weight. Easy to install. Transformerless Inverters and the NEC Any code discussion of TL inverters and ungrounded systems must begin with good working definitions of grounding.

Page 3 of 7 TRAINING BULLETIN An ungrounded array is an array which neither the DC positive nor negative current carrying conductors are bonded to ground. This is a requirement for the proper operation of TL inverters. This in no way effects the requirement for installing equipment grounding conductors (EGC). The metallic frames of modules and other components must still be grounded. TL inverters have been allowed by the NEC since 2005. The 2011 NEC [690.35] states: Photovoltaic power systems shall be permitted to operate with ungrounded photovoltaic source and output circuits where the system complies with 690.35(A) through (G) The following is a general explanation of the key components to comply with 690.35 to enable the use of TL inverters. Disconnects [690.35(A)] A means of disconnect must be provided for all DC current -carrying conductors [690.13]. The only exception is for grounded PV source and output conductors that shall not be connected to a switch, circuit breaker, or other disconnecting device per 690.13. For practical applications this means that a disconnect means must be provided for both positive and negative DC source and output conductors. Every SPR-p inverter contains a disconnect that opens all positive and negative conductors connected to the inverter simultaneously. All PV source and output conductors are ungrounded and therefore should also be color coded accordingly. All PV source and output conductors in an ungrounded system should be any color but white, grey, or green. Overcurrent Protection [690.35(B)] Overcurrent protection must be applied to all PV source and output circuits. Overcurrent protection must be connected to the ungrounded conductor(s). In the case of TL and ungrounded systems, both the positive and negative DC source conductors must be associated with overcurrent protection. There is a clear and important exception to this rule. NEC 690.9(A) exception (b) states that overcurrent protection is not required when the following situation is met: The short-circuit currents from all sources do not exceed the ampacity of the conductors or the maximum over -current protective device size specified on the PV module nameplate. This is a critical point for designing with SPR-p inverters. The inverters do not have integrated string fusing. Every SPR-p model has dual maximum power point trackers and the two trackers and the voltage boosters associated with them are electrically separate. DC voltage and current cannot flow backwards through them from the other tracker or from the utility grid. In this way they are like diodes which allow for the flow of electricity in only one direction. Current entering one tracker cannot back fed the other. A maximum of one string can be connected to each tracker for the 3.0, 3.6, and 4.2 kW SPRp models and a maximum of two stings can be connected to each tracker for the 5.0, and 6.OkW SPRp models. In these configurations there are only a maximum of two strings that are connected in parallel for any given tracker and therefore complies with 690.9(A) For more information about sizing series string fuses with SunPower modules, consult the Design section of your SunPower Technical Training Manual.

Page 4 of 7 Ground Fault Protection [690.35(C)] Ungrounded PV systems, like grounded PV systems, must have ground fault detection on the DC circuits. Not only does the system require DC ground fault detection but also a means of indicating that the fault has occurred as well as the ability to automatically cease supplying power to output circuits. Conventional inverters with isolation transformers provide ground fault protection through the GFDI fuse that bonds the current carrying conductor to ground. This fuse does not exist in the SPR-p line of TL inverters. Ground fault detection is done electronically in two ways in SPR-p inverters. 1. Each morning the inverter measures the resistance to ground for the current carrying conductors. It is looking for a high resistance, indicating that the insulation on all conductors is intact and no faults are present. This is similar to insulation resistance testing that may be performed when commissioning PV systems. If the system passes this impedance test, then the inverter turns on for the day. 2. During operation the inverter does continuous residual current monitoring. If it measures more than 300ma leaking to ground (indicating a failure of insulation and a ground fault) the inverter shuts off and registers a fault. Note that the threshold for registering a fault with TL inverters is significantly lower than the 1 amp requirement for inverters with grounded conductors. Photovoltaic Wire [690.35(D)] Conductors listed and identified as Photovoltaic Wire (PV Wire) must be used where ever there are exposed single conductors in the system. PV Wire has thicker insulation that helps keep the array ungrounded by preventing the likely hood that the current carrying conductor insulation will be damaged, creating an electrical connection to ground. For ungrounded systems, PV Wire should be used wherever USE-2 has traditionally been used, typically for conductors underneath the array. Once the conductors are no longer exposed, and have entered a transition box for example, conventional conductors in conduit can be used. Labels [690.35(F,) In addition to other labels required in PV systems, all junction boxes, combiner boxes, disconnects, or devices energized by ungrounded circuits that may be exposed during servicing, must carry the following label: Confidentiality -All information contained in SunPower Training Bulletins is confidential to SunPower Corporation and its designated Dealers.

Page 6 of 7 • 1 � SPR-p Inverter Important Notes The SPR-p inverter manuals should be read thoroughly before installing the product for the first time. The inverter's operation is simple with a few areas worth highlighting. Voltage Start The starting voltage for SPR-p inverters can be lowered, thus even further opening their DC voltage input window. This process is manual and must be done from the inverter menu screen once the entire PV system has been installed and is operational. The default starting voltage of the entire line of SPR-p inverters is 200 VDC. The inverter string sizing tool indicates whether a string selection will require modifying the Vstart voltage. SPR-p Model Differences SPR-p models differ slightly based on their part number and size. The following are some of the key differences by model. SPR-3000p, SPR-3600p, and SPR-4200p • Max of one string per maximum power point tracker • Vertically oriented DC disconnect SPR-5000p, and SPR-6000p • Max of two strings per maximum power point tracker • Horizontally oriented DC disconnect Contacting SunPower Training Department: For any additional questions please contact the SunPower Training Department at: TrainingSupport@SunPowerCorp.com Confidentiality -All information contained in SunPower Training Bulletins is confidential to SunPower Corporation and its designated Dealers.

Power derating can take place due to adverse environmental conditions or due to unsuitable input voltage values. The conditions forpower reduction due to environmental conditions and input voltage can also occur at the same time, but the power reduction will always relate to the lower value measured. Power reduction due to environmental conditions The power reduction value and the inverter temperature at which it oc- curs depend on the ambient temperature and on many operating para- meters. Example: input voltage, grid voltage and power available from the photovoltaic field. The inverter can therefore reduce the power during certain periods of the day and according to the value of these parameters. In any case, the inverter guarantees the maximum output power even at high temperatures, provided the sun is not shining directly on it.

Strings: X number of PV panels connected in series Array: group of X strings connected in parallel Strings and Arrays In order to considerably reduce the cost of installing a photovoltaic system, mainly associated with the problem of wiring on the DC side of the inverter and subsequent distribution on the AC side, the string technology has been developed. A photovoltaic panel consists of many photovoltaic cells mounted on the same support. • A string consists of a certain number of panels connected in series. • An array consists of two or more strings connected in parallel. Large photovoltaic systems can be made up of several arrays, connected to one or more inverters. By maximizing the number of panels inserted into each string, it is possible to reduce the cost and complexity of the connection system of the photovoltaic system. The current of each array must fall within the limits of the inverter. To work, the inverter must be connected to the national electricity grid since its opera- tion can be equated to a current generator that supplies power in parallel with the grid voltage. That is why inverters cannot support the grid voltage (islanding). POi ve 8118iI Characteristics \.^newable fneigySolu/ons 2 Description of the equipment This equipment is a multi -string inverter that converts direct electric cur- rent from a photovoltaic generator into alternating electric current and feeds it into the national grid. Photovoltaic panels transform energy from the sun into direct current (DC) electrical energy (through a photovoltaic field, also called photo- voltaic (PV) generator; in order to use it it is necessary to transform the type of alternating current into "AC". This conversion, known as DC to AC inversion, is made efficiently without using rotating parts and only through static electronic devices. In order to allow inverter operation in safe thermal and electrical condi- tions, in the event of adverse environmental conditions or unsuitable in- put voltage values, the unit automatically reduces the value of the power fed into the grid. This way the solar energy system compensates for the energy drawn from the utilities connected to the grid to which it is linked. The solar energy system therefore powers all connected electrical de- vices, from lighting to household appliances, etc. When the photovoltaic system is not supplying sufficient power, the power needed to ensure normal operation of the connected electrical devices is drawn from the national grid. If, on the other hand, excess power is produced, this is fed directly into the grid, so becoming avail- able to other consumers. In accordance with local and national regulations, the power produced can be sold to the grid or credited towards future consumption, so bring- ing about a saving of money.

Each multi -string inverter will work independently of the others and will supply the grid with the maximum power available from its section of photovoltaic panels. Notes on the sizing of the system Decisions about how to structure a photovoltaic system depend on a certain number of factors and considerations to make, such as for example, the type of panels, the availability of space, the future location of the system, energy production goals over the long term, etc. A configuration program that can help to correctly size the photovoltaic system is available on the web site of Power -One (www.power-one. com). PON/e/=0/1B® Characteristics 2 %,%Renewab/e fne�gy So/udons 1 � '', Z' Functionality and components of the equipment Data transmission and control The inverter, or a network of several inverters, can also be monitored remotely through an advanced communications system based on an RS-485 serial interface. The range of optional Power -One devices that can be connected to this communication line allows one to monitor the device locally or remotely via internet access. In addition, and again as an option, it is possible to use a monitoring sy- stem via radio by installing on the inverter itself the "PVI-Radiomodule" radio board in order to have a remote data visualization terminal with a wireless connection. Radiomodule The radiomodule board is an accessory that is used to add a radio com- munication line to the inverter. It can be used in parallel to the RS485 line for the transmission of data to the monitoring system. Configurable relay The inverter has a configurable switching relay that can be used in vari- ous operating conditions set in the dedicated menu. Atypical application example is the closing of the contact when an alarm occurs. Remote switching onloff This command can be used to disconnect/connect the inverter to the grid via an external (remote) command. This function must be enabled in the relevant menu and if it is operating, the connection of the inverter on the grid, besides being dictated by the presence of normal parameters, also depends on the external switching on/off control. Input poles grounding The circuit type of the inverter "isolated by a high -frequency transformer" allows, through special wiring located inside the inverter, for the connec- tion of one of the two input DC poles (positive or negative) to ground. It is also possible to have both the input DC poles "floating" and as such not grounded. Stand by Mode This functionality allows the inverter to remain on and grid connected even with an input voltage of less than 70Vdc. It is particularly useful in conditions of low irradiation and with passing shadowed areas that would cause continuous connections and disconnections to the grid. In- stead, with this functionality, the inverter starts to deliver power as soon as the input voltage exceeds the 80VDC without having to repeat the grid connection sequence. The time in which the inverter remains in this state can be set by acces- sing the Settings menu and activating the time for Input Undervoltage Protection (TprotM. If within the set time the conditions to export po- -23- -24- POW_ 00V - Characteristics L/;"Z"ble Energy So%/ions 2 wer to the grid do not reoccur (i.e. Vin>80VDC), the inverter disconnects from the grid and goes into SLEEP Mode. Sleep Mode This functionality turns off the inverter completely and the power absorp- tion is reduced to a minimum (0.6R. In this mode, the inverter allows display of the information available even in the absence of input voltage and therefore in the absence of sufficient irradiation of the photovoltaic panels. In fact, the display can be "awake- ned" by pressing any button on the display. After 30 seconds of inactivity the display will once again switch off au- tomatically. POW 0//e� Characteristics \ 1h,&4,ob/e Energy So/udo , 2 Topographic diagram of the equipment The diagram summarises the operation of the inverter. The main blocks are the DC -DC input converter (called "booster') and the DC -AC output inverter. Both, work at a high switch -over frequency, and so are small and relatively light. This inverter is equipped with a high frequency transformer, in other words with galvanic isolation of the primary (DC side) from the seconda- ry (AC side), while maintaining very high performance in terms of output and energy export. This type of circuit allows for the grounding of the inputs, both positive and negative, where required by the solar panel type used or by the rules of the country of installation. The inverter is equipped with a single input converter with maximum po- wer point tracking (MPPT) to which it is possible to connect two strings of photovoltaic panels Thanks to the high efficiency and the large heat dissipation system, a maximum power operation is guaranteed in a wide range of the ambient temperature without the use of external cooling fans. The inverter is controlled by two independent DSPs (Digital Signal Pro- cessors) and a central microprocessor. The connection to the power grid is thus kept under control by two inde- pendent monitors, in full compliance with the electric field norms both for power supply to the systems as well as security. The inverter is already equipped with all the protections necessary for safe operation and compliance with the norms. The operating system performs the operation of communicating with the relevant components to carry out data analysis. All this guarantees optimal operation of the entire unit and high efficien- cy in all insolation and load conditions, always in full compliance with the relevant directives, standards and provisions. -25- -26- c� 16 0 0 0 0 POW N Characteristics �Renewoble Energy5alutions �p ------------- ----n.. ��z}{ - ❑_ •T --- yl.-------------------- 27- POWe Characteristics '*,.IRenewable Energy Solutions Protective devices Anti-Islanding In the event of a local grid outage by the electricity company, or when the equipment is switched off for maintenance operations, the inverter must be physically disconnected safely, to ensure protection of people work- ing on the grid, all in accordance with the relevant national standards and laws. To prevent possible islanding, the inverter is equipped with an automatic protective disconnection system called "Anti-Islanding". 2 0 0 0 0 Ground fault in the photovoltaic panels An advanced ground fault protection circuit continuously monitors the ground connection and disconnects the inverter when a ground fault indi- cating this condition by means of the red GFI LED on the LED panel 14. This functionality is active also in the event of grounded connection of one of the two input poles of the inverter. Further protective devices The inverter is equipped with additional protective devices to guarantee safe operation in any circumstance. These protective devices include: - Continuous monitoring of the grid voltage to ensure the voltage and frequency values stay within operating limits; - Control of internal temperatures to automatically limit the power if nec- essary to ensure the unit does not overheat (derating). The numerous control devices produce a replete structure to guarantee totally safe operation. 2e - 0 0 0 0 POfVe OOe� 3 ` ,fenewob/eEnergy5o/unons _ 3 - Safety and accident prevention Safety instructions and general information The equipment has been manufactured in accordance with the strictest accident -prevention regulations and supplied with safety devices suitable for the protection of components and operators.

Environmental checks 6S. Consult the technical data to check the environmental parameters to be observed (degree of protection, temperature, humidity, altitude, etc.) Do not expose to direct sunlight to avoid unwanted power derating due to an increase in the internal temperature of the inverter. • Do not install in small closed rooms where air cannot circulate freely. • To avoid overheating, always make sure the flow of air around the inverter is not blocked. Do not install in places where gases or flammable substances may be present. • Do not install in rooms where people live or where the prolonged pres- ence of people or animals is expected, because of the noise that the inverter makes during operation. I • Avoid electromagnetic interference that can compromise the correct operation of electronic equipment, with consequent situations of danger. Installations above 2000 metres On account of the rarefaction of the air (at high altitudes), particular conditions may occur that should be considered when choosing the place of installation: • Less efficient cooling and therefore a greater likelihood of the device going into derating because of high internal temperatures. • Reduction in the dielectric resistance of the air that, in the presence of high operating voltages (DC input), can create electric arcs (discharges) that can reach the point of damaging the inverter. As the altitude increases, the failure rate of some electronic components increases exponentially because of cosmic radiation. All installations at altitudes of over 2000 metres must be assessed case by case con- sidering the aforesaid criticalities. POW 000" Installation 1 f Renewob/e Energy So/uNons Installation position When choosing the place of installation, comply with the following condi- tions: • Install on a wall or strong structure suitable for bearing the weight. • Install in safe, easy to reach places. • If possible, install at eye -level so that the display and status LEDs can be seen easily. • Install vertically with a maximum inclination of +/- V. If this condition is not complied with, the inverter could go into temperature derating be- cause of the worsening of heat dissipation. • To carry out maintenance of the hardware and software of the equip- ment, remove the covers on the front. Check that there are the correct safety distances for the installation that will allow the normal control and maintenance operations to be carried out. • Comply with the indicated minimum distances. • For a multiple installation, position the inverters side by side. • If the space available does not allow this arrangement, position the inverters in a staggered arrangement as shown in the figure so that heat dissipation is not affected by other inverters. -37- -38- c� 0 0 0 0 power-oae� Installation Renewable Energy SoluKens Wall/Pole mounting During installation do not place the inverter 02 with the front cover 04 facing towards the ground. • Position the bracket 01 perfectly level on the wall and use it as a drilling template. • Drill the 3 holes required using a drill with 10mm bit. The holes must be about 70mm deep.

Proceed to anchor the inverter to the bracket by tightening the lock- ing screw 03 located on the lower side. • Unscrew the 4 screws and open the front cover 04 upwards in or- der to make all the necessary con- nections. The cover is equipped with fixed hinges and cannot be removed. • Once the connections have been made proceed to closing the cover by tightening the 4 screws on the front to the torque indicated in the specifications. • Remove the protective film lo- cated on the front. 39 - EN c� 0 0 0 pewe -One® Installation \1Renewob/eb6fgy501LIAans Operations preparatory to PV generator connection Checking the correct polarity of the strings Using a voltmeter, check that the voltage of each string observes the correct polarity and falls within the input voltage limits accepted by the inverter (see technical data). If the voltage without load of the string is near the maximum value ac- cepted by the inverter, it must be borne in mind that with low ambient temperatures the string voltage tends to increase (in a different way ac- cording to the photovoltaic module used). In this case, it is necessary to carry out a check of the sizing of the system and/or a check on the connections of the modules of the system (e.g.: number of modules in series higher than the design number). Checking of leakage to ground of the photovoltaic generator Measure the voltage present between positive and negative pole of each string with respect to ground. If a voltage is measured between an input pole and ground, it may be that there is a low insulation resistance of the photovoltaic generator and the installer will have to carry out a check to solve the problem. Do not connect the strings if a leakage to ground has been found because the inverter might not connect to the grid. Requirements of the PV generator If the PV generator is made up of two or more strings it is necessary to remember that they must be formed by PV modules which have the same type and number of panels in series. In addition, they must have the same installation conditions (in terms of orientation in relation to the SOUTH and inclination in relation to the horizontal plane) All input parameters that must be met for the correct operation of the inverter are shown in the specifications. -40- power one rnsrarrarro►7 5 \„1Renewob/e Energy So/,bons Choice of differential protection downstream of the inverter Based on the current CEI 64.8 Norms and Variant 4 (V4) of September 2006, which in Section 712: "Solar photovoltaic power systems (PV)" ad- dresses photovoltaic applications, with particular reference to paragraph 712AI3: "Protection against indirect contact", the following may be noted: 712A13.1.1.1.2 When an electric system includes a PV power supply sys- tem without at least a'simple separation between the AC side and the DC side, the differential device installed to provide protection against indirect contact by automatic disconnection of the power supply must be of the B type in accordance with IEC 607551A 2. When the PV inverter is not in terms of its construction such as to put continuous ground fault current (cc) into the electrical system, a differen- tial switch of type B is not required according to IEC 60755/A2. Note: The first section of the article, in reference to the `simple separation between the AC side and the DC side", considers isolation transformers that operate at low frequency (grid frequency). Aurora Power -One inverters with a high frequency transformer are equipped with an isolation transformer for each of the DC/DC converters which operates at high frequency (switch -over frequency of the convert- er). This transformer allows for high frequency galvanic isolation between the DC and AC side of the system. In addition to this the inverters include protection mechanisms so that they cannot input ground fault currents. Power -One Italy S.p.A. declares that the Power -One Aurora high -frequen- cy isolated inverters are in terms of their construction continuous ground fault currents and therefore, in accordance with Article 712.413.1.1.1.2 of Section 712 of CEI 64-8f7 Norms there is no requirement that the dif- ferential installed downstream of the inverter is type B in accordance with IEC 60755 /A 2. Power -One recommends the use of a switch with type A or AC differential magneto - thermal protection with lAn=3OmA sensitivity. pow r one® rnstarratlof, 5 WRenewableEnergySolutions Inverter Components For both of the inverter 02 models (2 kW or 2.5 kW) two different set-ups are available: UNO-X.X-I-OUTD: Standard version UNO-X.X-I-OUTD-S: Version equipped with DC disconnect switch 07 Standard version S Version Table: electrical system components Ref.

For the correct operation, some photovoltaic panels require the connec- tion of the potential of the positive terminal to the earth terminal, or to . have both of the input poles floating in regards to ground potential. In order to achieve this, it is possible to vary the default configuration, . moving the connector installed in a03 (negative grounding) to a04 (positive grounding) or a02 (floating configuration). The configuration of the grounding of the inputs must be done before any connections or testing takes place. Incorrect configuration may cause damage to the system and photovoltaic panels! Input connection to the PV generator (DC side) After undergoing preliminary checks and as such having verified that there are no problems in the photovoltaic system, you can connect the inverter to the inputs. To prevent electrocution hazards, all the connect operations must be carried out the DC disconnect switch 07 or the external disconnect switch open and locked. Standard version S Version For the string connections it is necessary to use the quick fit connectors (multicontact or weidm011er) located on the bottom of the mechanism. The maximum numbers of input strings which can be connected is 2. Connect all the strings included in the design of the system and always check the tightness of the connectors. If some of the string inputs should not be used you must proceed to verify the presence of covers on DC input connectors 10 and then install them should they be absent. This operation is necessary for the tight- ness of the inverter and to avoid damaging the free connector that could be used at a later date. The two pairs of DC input connectors 10 are internally related to a single input channel, so there are no preferences on the connectors to be used in the case of installation of a single string. m N O O O POfV C O/le® Installation \lAenewoble Energy 5olahons Procedure for installing quick fit connectors On the inverter models that provide quick coupling connectors, these can be provided in two different types: WEIDMULLER The installation of Weidmuller connectors does not require special tools. - Strip the end of the cable to which you are going to attach the connec- tor (after making sure it conforms to the limits of the connector).

The distributor grid during the phase of connecting to the grid will then provide forapplication of the lead sealing. 45- -46- POW *"% installation Renewable Energy So/uhons Main board Main board 05 Ref. manual Ref. inverter Description a01 J9-AID Inputvadstors a02 J5 Connector for floating ground of the inputs a03 J7 Connector for negative grounding of the inputs a04 JB Connector for positive grounding of the inputs a05 F1 - J25 PTC a06 J11 - J12 Output varistors a07 J4 Inverter data memory card housino a08 BT1 Battery housing a09 S1 - S2 Rotary switches for setting the standard of the country and the language of the display a10 S3 Switch for setting the termination resistance of the RS485 line all J16 RS485 communication card housing a12 J13 - J14 Connection of the RS485 line on RJ45 connector 09 J21- J22 AC output terminal board POWe Installation \1Renewab1e Energy So/udons Connections of the signals to the main board Each cable which must be connected to the connectors of the com- munication and control signals must pass through the two service cable glands 06 (shown in the picture). The available cable glands are two M20s that can take a cable with a diameter of 7 mm to 13 mm. Two -hole gaskets are supplied for insertion in the cable gland, which allow two separate cables with cross-section of up to 5 mm to go through. The signal cables are connected to the main board 05 inside the inverter by means of the terminal connectors supplied. Serial Connection Communication (RS485) On the inverter there is a RS485 communication line, dedicated to con- necting the inverter to monitoring devices or to carrying out "daisy -chain" ("in -out') connections of multiple inverters. The RS485 connecting cables can use both the terminal connectors 1g_4 as well as the RJ45 connectors to be connected to the dedicated port a12. Connection of conductors with RJ45 connectors a12 The RJ45 connectors (A) and (B) available for the RS485 communica- tion, are equivalent to each other and can be used interchangeably for the arrival or for the output of the line in realising the daisy chain connec- tion of the inverters. a12 I 1 The same is true for connections made using the terminal connectors n n` a14. fuuf -47- -48- Mwe!-ooe� \lRenewoble Energy Solulions Installation 5 Table: crimping scheme connectors RJ45 Pin N° Function � a 1 not used 2 not used TOP 3 +T/R 4 notused 5 -T/R FRONT 6 not used t a 7 RTN 8 not used Use a connector with metal body to provide cable shield For long distance connections, the connection on terminal connector is continuityl preferable using a shielded twisted pair cable with characteristic imped- ance of Z0=120 Ohm like the one shown in the following table: Shield continuity must be provided along the communication line using the LNK ter- minal and must be grounded at a single point. Procedure for connection to a monitoring system Connect all the units of the RS485 chain in accordance with the "daisy - chain" arrangement ("in -our) observing the correspondence between signals, and activate the termination resistance of the communication line in the last element of the chain by switching switch 11Q (to ON posi- tion). Poiv r DOe� Installation WRenewoble Energy So/udons If a single inverter is connected to the monitoring system, activate the termination resistance of the communication line by switching switch al (to ON position). Set a different RS485 address on each inverter of the chain. No inverter should have "Auto" as its address. An address can be chosen freely from out of 2 to 63. The address on the inverter is set through the display and the push- button panel (see relevant chapter). We recommend not exceeding a length of 1000m for the communication line. No more than 62 inverters can be connected to the some RS485 line. "pWhen using an RS-485 connection, if one or more inverters are added later to the system, you must remember to return to OFF position the switch of the termination resistance used (PC or PMU) of the inverter that was previously the last one of the system. oo Each inverter is dispatched with two (2) as the predefined RS485 ad- dress and with switch for setting termination resistance al to OFF posi- tion. e ON 53 Monitoring system via serial (RS485) The RS485 line can be connected to various monitoring devices that can be in local or remote mode: • Local monitoring from PC with PVI-USB-RS485_232 adaptor and Aurora Communicator software • Local monitoring from remote display with PVI-DESKTOP device • Remote monitoring with PVI-AEC-EVO monitoring system and Portal P1 For local monitoring, Power -One recommends connecting its PVI-USB- RS485_232 adaptor between the first unit of the daisy -chain and the computer. Equivalent devices found on the market can also be used for the same purpose, but, bearing in mind that they have never been specifically tested, Power -One cannot guar- antee correct operation of the connection. Please note that these devices may also require an external termination impedance, whereas this is not necessary with the Aurora PVI-USB- RS485_232. 49- -50- POfV C 000� Installation `, f Renewob/e fneigy So/utians ' "' " Monitoring System via Radiomodule The radiomodule card is an accessory for the data transmission via ra- dio waves to a monitoring device. The radiomodule card is installed on the main board 05 vertically, by connecting the two a13 connectors and screwing the anchoring screws. In turn wiring ending with an antenna installed outside the inverter is connected to the radiomodule: The part of the inverter where the antenna will be installed will be in the place of one of the service cable glands 06 of M20 measurements. The monitoring is carried out using the PVI-DESKTOP device. Configurable relay connection The inverter has a multi -function relay a09, whose switching can be ?? configured. It can be connected with normally open contact (being con- nected between the NO terminal and the common contact C) and with normally closed contact (being connected between the NC terminal and the common contact Q. This contact can be used in four different operating configurations that a15 can be set in the dedicated menu. Operating modes O DOD 0 • Production: the relay switches whenever a connection to (and there- fore a disconnection from) the grid occurs. So if the NO (or NC) contact is chosen, the contact will stay open (or closed) until the inverter is connected to the grid; once the inverter con- O O nects to the grid and starts to export power, the relay switches state and DUD therefore closes (or opens). When the inverter disconnects from the grid, the relay contact returns to W9' its position of rest, namely open (or closed). • Alarm: the relay switches whenever there is an alarm on the inverter INC = Normally closed (Error). No switching occurs when there is a Warning. C = Common contact So if the NO (or NC) contact is chosen, the contact will stay open (or NO = Normally open closed) until the inverter reports an error; once the inverter reports an error, the relay switches state and therefore closes (or opens). -51- Installation5 �,�Renewob/e Energy Sa/u/ans The contact remains switched from its rest condition until normal opera- tion is restored. • Alarm (configurable): the relay switches whenever there is an alarm (Error) or a Warning, which have been previously selected by the user through the dedicated menu. If the NO (or NC) contact is chosen, the contact will stay open (or closed) until the inverter reports an error or a warning out of those selected from the menu; once the inverter displays an error or a warning out of those selected, the relay switches state and therefore closes (or opens) the contact. The relay remains switched from its rest condition until the alarm or warning has disappeared. • Crepuscular: the relay usually switches when the voltage from the photovoltaic generator exceeds/falls below the threshold set for grid connection. If the NO (or NC) contact is chosen, the contact will stay open (or closed) until the inverter has an input voltage higher than the one selected for grid connection. The contact remains switched from its rest condition for as long as the inverter is switched on (even if not connected to the grid). This mode is useful for disconnecting large output transformers that could have unnecessary consumption during the night. The device to be connected to the relay can be of different types (light, sound, etc) but must comply with the following requirements: Alternating current Maximum Voltage: 240 Vac Maximum Current:1 A Direct current Maximum Voltage: 30 Vdc Maximum Current: 0.8 A Cable requirements External diameter: from 5 to 17 mm Conductor cross-section: from 0.14 to 1.5 mmz -52- c� v 0 0 0 0 0 Installation Installation pow r one 5 power ore® 5 '�„�Renewob/e fneigy So/uNons \IRenewob/e fneigy So/u/ions Remote control connection Standard grid setting of the country and language display The connection and disconnection of the inverter to and from the grid There are different grid parameters (dictated by the electricity distributor) can be controlled through an external control. according to the country in which the inverter is installed.

The equipment operates automatically without the aid of an operator; operating state is controlled through the instruments. The interpretation orvarfation ofsome data is reserved exclusively forspecialized and qualified staff. The incoming voltage must not exceed the maximum values shown in the technical data in order to avoid damaging the equipment. Consult the technical data for further details. Even during operation, check that the environmental and logistic conditions are correct (see installation chapter). Make sure that the said conditions have not changed over time and that the equipment is not exposed to adverse weather conditions and has not been isolated with foreign bodies. PON/ 0/!e® Operation7 Renewob/e fneigy So/uh'ans Monitoring and data transmission As a rule, the inverter operates automatically and does not require spe- cial checks. When there is not enough solar radiation to supply power for export to the grid, (e.g. during the night) it disconnects automatically. In this mode data consultation on the display 12 is possible (holding down any one key of the keypad 13, the display is activated). The operating cycle is automatically restored when there is sufficient solar radiation. At this point, the luminous LEDs on the LED panel 14 will indicate this state. User interface mode The inverter is able to provide information about its operation through the following instruments: • Warning lights (luminous LEDs) • LCD display for displaying operating data • Data transmission on dedicated RS-485 serial line. The data can be collected by a PC (using the signal converter PVI-USB-RS485 232) or a data logger equipped with an RS-485 port (PVI-DESKTOP / PVI-AEC- EVO). Contact Power -One assistance for any doubts about the compa- tibility of the devices. Types of data available The inverter provides two types of data, which are usable through the relevant interface software and/or through the display 12. Real-time operating data Real-time operating data can be transmitted on request through the communication lines and are not recorded in the inverter. For data trans- mission to a PC, the free software supplied with the inverter can be used (please check at www.power-one.com for more updated versions). Internally stored data The inverter internally stores a set of data that are necessary for pro- cessing statistical data and an error log with time marking. -59- -60- now r ofle® _ oerrfof� 7 Renewable Fnegy Soluhans Commissioning Do not place objects of any kind on the inverter during operation) Do not touch the heatsink while the inverter is operating) Some parts may be very hot and cause bums.

This icon will remain permanently switched on when the DC -DC will be operating at steady state (the flashing of the 53�F k icon usually lasts a few seconds). Immediately after this, the bl8 icon, which indicates the AC -DC circuit (inverter) part, will also behave normally.

During this phase r the icons will be displayed in sequence on the b21 board until the con- nection of the inverter. After the inverter is connected, the icons on the Inverter connected to the grid whole line b21 will come on steady. If the inverter disconnects from the grid, the icons of the left side (cable and plug) of the line b21 will stay on. • Once the connection sequence has been completed, the inverter starts to operate and indicates its correct operation by making a sound and by the green LED coming on steady on the LED panel 14. This means there is sufficient solar radiation to feed power into the grid. I BEEP • If the checking of the grid does not give a positive result, the unit will repeat the procedure until all the parameters that allow connection to the grid (grid voltage and frequency, insulation resistance) are within the range. During this procedure, the green LED flashes. At the end of the first starting of the inverter, the wiring box must be configured using the dedicated Aurora Manager software.

At the same time, the main readings made by the inverter will be dis- played in rotation on the graphic display bl0. • Display of the power graph toll The histogram includes 16 horizontal units and 20 vertical units. The period of time is represented by the horizontal axis of the graph and can be set by the user to 8, 16 or 24 hours; therefore, each horizontal unit can represent 30, 60 or 120 minutes. The vertical axis represents the maximum power derating (2.2kW for the UNO-2.0-1-OUTD and 2.75kW for the UNO-2.5-IOUTD) and therefore 100% corresponds to this outgoing exported power value. Finally, bear in mind that the power value expressed by each column of the graph represents the average value of the power during the period relating to the horizontal unit. -63- -64- Power one® Operation �, jRenewab/e fneigy So/udons , LED behaviour The following table shows all the possible combinations of activation of = LED on the LEDs, situated on the LED panel 14 in relation to the operating state 9 = LED flashing of the inverter. ® = LED off (x) = Any one of the conditions described above Table: LED behaviour Status of the LEDs Operating state Notes green: ® Night mode (auto The inverter is in night time switch -off mode (input voltage yellow: (9 switch -off of the 70% less than the start-up voltage set for both inputs). red: ® inverter) green: ® Inverter initialization This is a transition state due to the checking of the yellow: ® (loading of settings and operating conditions.

Insulation fault LED What to do after an insulation fault warning When the red LED comes on, first try to reset the warning through the multi -function button ESC on the LED panel 14. If the inverter duly reconnects to the grid, the fault was due to temporary phenomena. We advise having the system inspected by the installer or a specialized technician if this malfunctioning occurs frequently. If the inverter does not reconnect to the grid, make it safe by isolating it (by means of the disconnect switches) on the both the DC side and the AC side, and then contact the installer or an authorized service centre to have the photovoltaic generator fault repaired. -65- -66- POwe%o Ae Operation 7 vRenewob/e Energy Solu7ions Description of the menus The display 12 has a section b110 (graphic display) for moving through the menu using the buttons of the LED panel 14.

We ADVISE you to be very careful in memorizing the new password. If the Password is misplaced, it will not be possible to access the inverter, since there is no Reset function for security reasons. • Currency This section of the menu allows you to set the name of the currency and the value given to 1 kWh of energy produced. The correct setting of these parameters allows you to display the actual earning/saving given by the system. Name: the chosen value is set (default is Euro) Val1KWh: indicates the cosVincentive of 1 KWh expressed in the chosen currency (default is 0.50). • DateRme Allows you to set the current date and time (daylight saving time not included) -Language Allows you to set the required menu language • Vstart This section of the menu allows you to set the Vstart voltage (separately for both channels if they are configured in independent mode or avail- able), to adapt it to the requirements of the system. 10 We advise changing the activation voltage only if really necessary and to set it to the correct value: the photovoltaic generator sizing instrument available on the Internet site of Power -One indicates whether it is necessary to change the Vstart and the value to set. • Alarm This section of the menu allows you to set the switching of a relay con- tact (available as a normally open contact — N.O. — and also as a nor- mally closed contact — N.C.). This contact can be used, for example, to: activate a siren or a visual alarm, control the disconnect device of an pewe%one Operation `/Renewab/e Eneigy So/ulians external transformer, or control an external device. Maximum ratings of the alarm contact: 240Vac/IA and 30Vdc/0.8A The switching of the relay can be set in 4 different modes: PRODUCTION: the relay switches when the inverter connects to the grid. ALARM: the relay switches when there is an alarm (code Q. ALARM (conf.): the relay switches ifthere are alarms (code E) or wam- ings (code "chosen by the user from a list (the list may also show choices that are not envisaged for the specific model). CREPUSCULAR: the relay switches only when it exceeds the input voltage set for connection to the grid. • Remote Control This section of the menu allows you to enable/disable the connection/ disconnection of the inverter toKrom the grid through the relevant control signal (+R/-R). Disable: the connection/disconnection of the inverter to/from the grid is dictated by the input (voltage from the photovoltaic generator) and out- put (grid voltage) parameters of the inverter. Enable: the connection/disconnection of the inverter to/from the grid is dictated by the state of the +R signal compared to the -R signal as well as by the input (voltage from the photovoltaic generator) and output (grid voltage) parameters of the inverter. • UV prot. T This section of the menu allows you to set the time for which the inverter stays connected to the grid after the input voltage has dropped below the Under Voltage limit (set at 70% of Vstart). Power -One sets the time at 60 sec. The user can set it at from 1 to 3600 sec. Example: with the UV Prot.time set at 60 seconds, if the Vin drops below 70% of Vstart at 9:00, the inverter stays connected to the grid (taking power from it) until 9:01. • MPPT This section of the menu allows you to set the parameters of the maxi- mum power point search (MPPT) function. This function is useful when there are shadowed areas on the PV generator that can create several maximum power points in the work curve. MPPT amplitude: the amplitude of the interference introduced in DC is chosen through the setting of this parameter to establish the optimal working point. There are 3 settings to choose from (LOW, MEDIUM, HIGH). The default setting is MEDIUM. Multi -max scan: through the setting of this parameter, you can enable/ disable the scan, decide the frequency with which the scan is carried out and override it manually. Enable/Disable: Enables/Disables the scan for identifying the maxi- mum power point of the system. 73 - - 74 - POWef- 9* Operation vRenewob/e EnergySo/u8onsI Z ''1 7 Scan Interval: this allows you to set the interval of time between scans. It must be borne in mind that, the shorter the interval between scans, the greater will be the loss of production due to the fact that, during the scan, energy is transferred to the grid but not at the maximum power point. Each scan takes 2 seconds. Manual Scan: Allows you to start (asynchronously to the periodicity set through the Scan Interval) the manual scanning of the photovoltaic gen- erator for peak point tracking. • Alarm Msg This section of the menu allows you to enter a customized message that is displayed on the display immediately after the specific error message has been displayed. EnablelDisable: Enables/Disables the display of customized messages Writing of Msg: you can write your customized message that can be written on two lines of 16 characters each. To write the message, use the UP/DOWN arrows to choose the character you wish to enter and press ENTER to confirm. PON/e/=00e® Operation7 \JRenewob/eEnergySolutions Information menu • Product ID Allows you to display the product identification code. • Serial No. Allows you to display the serial number of the equipment. • Firmware Allows you to display the revision of the firmware installed in the equip- ment. • Country selector Allows you to display information regarding the grid standard set with the rotary selectors. Current value: Displays the set grid standard. New value: If the position of the rotary swatches is changed (a new grid standard is therefore selected) during operation, the new stand- ard selected will be displayed but will be made effective only after the equipment has been switched off and then on again and only if the time remaining for carrying out this operation has not expired (24h of opera- tion). - Set new: Allows you to confirmiset the new grid standard set in the "New value" section of the previous menu. When this function is used, there will be no correspondence between the standard selected on the display and the position of the rotary selectors. - Time remaining: Displays the time remaining in which it is still pos- sible to set a new grid standard. When the time expires, "Locked" will be displayed, which indicates it is not possible to change the grid standard again. -75- -76- POWe ON 8 POWe O/!e� Maintenance8 WRenewab/e Energy Sa/Mons \, jRenewob/e Energy Sa/a/ onS Routine maintenance For routine maintenance operations is recommended to be carried out by the installer or qualified staff. 8 - Maintenance Table: routine maintenance Perform necessary cleaning of the equipment; verify, in annually oras particular, the cleaning of the heat sink 15, in order to avoid obstructions General conditions that could compromise the airflow.

To check this, measure the voltage between the positive pole and ground and between the negative pole (of the PV generator) and ground using a voltmeter whose input accepts a voltage of at least 1000 Volts. Behaviour of a system without leakage The internal resistance of the vol- tmeter tends to zero the voltage present on the PV generator due to the capacitive effect. How to make the measurement: ►U Due to the capacitive effect of the PV generator, during the first mo- ments that the voltmeter is connected between one of the two poles and ground, it will measure a voltage of about Voct2, which will tend to stabilize around OV if there is no ground leakage, as shown in the graph below: Voc -85- Volt 1•) POW 01m. Maintenance Q \,1Renewoble Energy So/Mons Q Behaviour of a system with leakage If the voltage measured between one of the two poles and ground does not tend to OV and stabilizes on a value, there is a ground leakage from the PV generator. Example: When the measurement is made between positive pole and ground, a voltage of 200V is measured. This means that if the system is made up of 10 modules in series and each one supplies 50V, the leakage can be located between the 4th and 5th PV module.
