Never work with live wires! Prior to all connection work, make sure that the AC and DC wires are not charged. WARNING! Incorrect operation and work performed incorrectly can cause serious injury & damage! Only qualified staff are authorized to install your SunPower SPRf inverter and only within the scope of the respective technical regulations. Do not start operation or carry out maintenance work before you have read the chapter ‘Safety Instructions’! Protection of persons and equipment The design and function of the SunPower SPRf inverter offers a maximum level of safety, both during installation as well as in operation. The SunPower SPRf inverter provides operator and equipment protection through: a) galvanic isolation b) monitoring the grid Galvanic isolation The SunPower SPRf inverter is equipped with a high frequency transformer that ensures galvanic isolation between the DC side and the grid, thus ensuring the highest possible safety. Monitoring the grid Whenever conditions in the electric grid are inconsistent with standard conditions (for example grid switch-off, interruption, etc.), your SunPower SPRf inverter will immediately stop operating and interrupt the supply of power into the grid. 7 SunPower Monitoring the grid (continued) Your SunPower SPRf inverter determines the grid’s status by: - monitoring voltage - monitoring frequency - monitoring islanding conditions Information for Field adjustable trip points The SunPower SPRf inverter is provided with field adjustable trip points. For further information please contact SunPower Corp. technical support E-Mail: techsupport@sunpowercorp.com FCC Compliance This device complies with Part 15 of the FCC Rules. Operation is subject to the following conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Ground Fault Detector / Interruptor The SunPower SPRf inverter is equipped with a ground fault detection and interruption (GFDI) circuit as required by UL 1741 and the National Electrical code. Depending on the system configuration either the PV array’s negative or positive conductor is connected to the grounding system in the inverter. If a ground fault occurs in the DC wiring, the inverter disconnects from the grid. Standards and Regulations Your SunPower SPRf inverter complies with the requirements for the following standards "Inverters, converters and controllers for use in independent power systems": - UL1741-2005 - IEEE 1547-2003 - IEEE 1547.1 - ANSI / IEEE C62.41 - C22.2 No. 107.1-01 (Sep. 2001) The ground-fault detection and interruption is in compliance with NEC 690 building code requirements. Product listings and compliance The respective conformity declarations can be found in the appendix to these operating instructions. 8 SunPower The SunPower SPRf Inverter in the PV System General information The SunPower SPRf inverter is the highly complex link between solar modules and the grid. SunPower SPRf inverter Main AC Load Center PV array Energymeter Tasks The main tasks of the SunPower SPRf inverter include: - Converting DC into AC current - Fully automatic operation management - Display function and data communication Converting DC into AC current The SunPower SPRf inverter transforms the direct current generated by the solar modules into alternating current. This alternating current is fed into your home system or into the utility grid and synchronized with the voltage that is used there. Important The SunPower SPRf inverter has been designed exclusively for use in grid connected photovoltaic systems. It cannot generate electric power independent from the grid. Fully automatic operation management The SunPower SPRf inverter is fully automatic. Starting at sunrise, as soon as the solar modules generate enough power, the automatic control unit starts monitoring voltage and frequency. As soon as there is a sufficient level of irradiance, your solar inverter starts feeding energy to the grid. The control system of the SunPower SPRf inverter ensures that the maximum possible power output is drawn from the solar modules at all times. This function is called MPPT (Maximum Power Point Tracking). 9 SunPower Fully automatic operation management (continued) As dusk starts and there is no longer sufficient energy available to feed power into the grid, the SunPower SPRf inverter shuts down the grid connection completely and stops operating. All settings and data recorded are saved. Display function and data communication The display on the inverter is the interface between the inverter and the operator. The design of the display is geared towards simple operation and making system data available as long as the inverter operates. The SunPower SPRf inverter is equipped with a basic logging function to monitor minimum and maximum data on a daily and a cumulative basis. These values are shown on the display. There is also an option to allow the reading of the following weather data on the display: - two different temperature readings (for example, temperature at the solar modules as well as the outside temperature) - irradiance A wide choice of data communication products allows for many possibilities of recording and viewing data. System Upgrades The SunPower SPRf inverter is designed for various system upgrades, e.g.: - Upgrades that enable SunPower SPRf inverter to communicate with external system upgrades as well as other inverters - Datalogger and modem interface, Ethernet/Internet connection (for using a PC to record and manage data from your photovoltaic system) Forced ventilation The temperature controlled, variable speed fan with ball bearing support of the SunPower SPRf inverter provides: - optimal inverter cooling - efficiency increases - cooler components, thus improving service life - least possible energy consumption and noise level Power Derating Should there be insufficient heat dissipation in spite of the fan operating at maximum speed (for example inadequate heat transfer away from the heat sinks) the power will be derated for protection of the SunPower SPRf inverter. Derating the power reduces the output of the SunPower SPRf inverter for a short period sufficient to ensure that the temperature will not exceed the admissible limit. Your SunPower SPRf inverter will remain ready for operation as long as possible without any interruption. 10 SunPower Installation and Startup 11 SunPower 12 SunPower SunPower SPRf Inverter Installation and Connection Safety WARNING!

(20 cm) minimum between each inverter or anything to the right or left of the inverters such as Walls or DC and AC disconnects. For optimal airflow and cooling efficiency in hot climates SunPower Corp. recommend a distance of 10 - 12 in. (25 - 30 cm). When installing more than one unit, keep a distance of 12 in. (30 cm) between each SunPower SPRf inverter. Keep a distance of 8 in. (20 cm) minimum above each inverter or anything above the inverters such as ceilings, roofs or covers. The air flow direction within the inverter is from right to left (cold air intake on right, hot air exit on left). When installing the SunPower SPRf inverter in a switch panel cabinet (or similar closed environment) it is necessary to make sure that the hot air that develops will be discharged by forced ventilation. The SunPower SPRf inverter is designed for installation both indoors and outdoors. Choosing a Location for Inside Installation During certain operation phases the SunPower SPRf inverter may produce a slight noise. For this reason it should not be installed in an occupied living area. Do not install the SunPower SPRf inverter in: - areas with large amounts of dust - areas with large amount of conducting dust particles (e.g. iron filings) - areas with corrosive gases, acids or salts - areas where there is an increased risk of accidents, e.g. from farm animals (horses, cattle, sheep, pigs, etc.) - Stables or adjoining areas - Storage areas for hay, straw, chaff, animal feed, fertilizers, etc. - Storage or processing areas for fruit, vegetables or winegrowing products - Rooms used in the preparation of grain, green fodder or animal feeds - Greenhouses 19 SunPower Choosing a Location for Outside Installation NEMA 3R protection means that the SunPower SPRf inverter can be exposed to moisture. However, we recommend that direct moisture and direct water spray such as a sprinkler be avoided, if possible. In order to protect the display, the SunPower SPRf inverter should not be exposed to direct sunlight. Ideally, the SunPower SPRf inverter should be installed in a protected location, e.g. near the solar modules or under a roof overhang. 20 SunPower SunPower SPRf Inverter Installation General Important Depending on the surface, different dowels and screws may be required for installing the wall bracket.

The inverter opencircuit voltage should never rise above 600 Volts. Whenever the open-circuit voltage of the solar modules exceeds 600 Volts, the SunPower SPRf inverter may be damaged, and all warranty rights will become null and void. More exact data for sizing the solar array for the particular location can be obtained using SunPower string configuration tools. WARNING! An electrical shock can be fatal. Danger from grid voltage and DC voltage from solar modules. - The connection area should only be opened by a licensed electrician. - The separate power stage set area should only be disconnected from the connection area after first being disconnected from the grid power. - The separate power stage set area should only be opened by service personnel trained by SunPower Corp. Never work with live wires! Prior to all connection work, make sure that the AC and DC wires are not charged. The DC main switch is only used to switch off power to the power stage set. When the DC main switch is turned off, the connection area is still energized. 32 SunPower DC-Terminals DC+ DC- DC+ and DC- terminals on the SunPower SPRf inverter Overview ‘Connecting Solar Module Strings to the SunPower SPRf inverter (DC)’ includes the following sections: - Connecting Solar Module Strings Criteria for the Proper Selection of String Fuses Solar Module Grounding 33 SunPower Connecting Solar Module Strings Wire Cross Section of Solar Module Strings Connecting Solar Module Strings WARNING!

Series fusing may be required depending on the type of PV module used in the system. See NEC 690.9. 1 Select string fuses according to the information from the solar module manufacturer or as per ‘Criteria for the Proper Selection of String Fuses’ (max. 20 A per DC input terminal) Important - Follow all solar module safety instructions - Follow all solar module manufacturer requirements 36 SunPower Inserting String fuses into the SunPower SPRf inverter (continued) WARNING! An electrical shock can be fatal. Danger from DC voltage from solar modules. Fuse covers are for installation purposes only. They offer no protection against contact. NOTE - Insert fuses only with a fuse cover in the respective fuse holder - Do not operate the SunPower SPRf inverter without fuse covers 2 1 DC+ 2 3 4 DC+ 37 SunPower Criteria for the Proper Selection of String Fuses DC disconnect requirements NEC 690.15-18 allows the use of fuse holders as a suitable means of disconnecting PV arrays for servicing. Additional DC disconnects external to the inverter may be required by the local authority having jurisdiction. General The use of string fuses in the inverter also adds fuse protection to the solar modules. A crucial factor for the fuse protection of solar modules is the maximum short circuit current (ISC) of the respective solar module. Criteria for the Proper Selection of String Fuses The following criteria must be fulfilled for each solar module string when using fuse protection: - IN > 1.25 x 1.25 x ISC - IN < or = the series fuse rating of the module - VN >/= 600 V DC - Fuse dimensions: Diameter 10.3 x 35 - 38 mm IN ....... Nominal current rating of fuse ISC ..... short circuit current for standard test conditions (STC) according to solar module data sheet VN ..... Nominal voltage rating of fuse NOTE The string fuse size must not be greater than the maximum fuse size rating of the PV module. Effects of using underrated fuses In underrated fuses, the nominal current value is less than the short circuit current of the solar module. Effect: The fuse may trip in intensive irradiance conditions. 38 SunPower Fuse Recommendations Application Example NOTE Only select fuses suitable for a voltage of 600 V DC. Example: Maximum short circuit current (ISC) of the solar module = 5.75 A According to the criteria for selecting the correct fuse for an uncombined series string, the fuse must have a minimum nominal current greater than the short circuit times 1.25 (edge of cloud effect) x 1.25 (continuous duty): 5.99 A x 1.25 x 1.25 = 9.36 A The fuse that should be selected according to the Fuses table is a 10.0 A fuse (KLKD D 10) or another size up to the maximum series fuse rating of the module (15 A or 20 A depending upon the module). Fuses Nominal current value Fuse Nominal current value Fuse 1.0 A KLK D 1 6.0 A KLK D 6 1.5 A KLK D 1 1/2 7.0 A KLK D 7 2.0 A KLK D 2 8.0 A KLK D 8 2.5 A KLK D 2 1/2 9.0 A KLK D 9 3.0 A KLK D 3 10.0 A KLK D 10 3.5 A KLK D 3 1/2 12.0 A KLK D 12 4.0 A KLK D 4 15.0 A KLK D 15 5.0 A KLK D 5 20.0 A KLK D 20 ‘Fuses’ table: Excerpt of suitable fuses, e.g. Littelfuse fuses 39 SunPower Solar Module Grounding General The SunPower SPRf inverter is designed for a solar module ground at the positive pole. The solar module ground is carried out via a fuse in the inverter. Solar module DC+ Inverter = ~ DC main switch String fuse GFDI fuse N L1 L2 L3 GND DCSolar module ground at positive pole with fuse SunPower Corporation recommends a fuse with 1 A and a dimension of 10 x 38 mm for solar module grounding. A corresponding fuse comes inserted in the fuse holder for the solar module ground. Safety WARNING! An electric shock can be fatal. Normally grounded conductors may be ungrounded and energized when a ground fault is indicated. The ground fault has to be repaired before operation is resumed. NOTE Do not connect the ground to the DC positive at any point! This is already done within the SunPower SPRf inverter. If the DC positive is connected to ground at the DC terminal block or prior, this will circumvent the GFDI protection system, preventing your SunPower SPRf inverter from properly detecting a fault current. Additionally, turning the DC disconnect to the off/opencircuit condition will not disconnect the array from ground, as it only disconnects the DC negative. The inverter factory setting triggers the following when there is a defective fuse: - the status message ‘STATE 551’ is shown on the display - the Operating Status LED flashes green - power input to the grid is not interrupted NOTE To avoid damaging solar modules, the error should be corrected as soon as possible. 40 SunPower Safety (continued) If the error goes uncorrected for a long period of time: - the status message ‘STATE 471’ is shown on the display - the Operating Status LED lights up red - the inverter interrupts power input to the grid until the fuse has been replaced 41 SunPower Attaching Power Stage Sets and Closing the SunPower SPRf Inverter Preparation 2 1 1 2 5 3 8 6 1 4 7 2 Attaching Power Stage Sets And Closing the SunPower SPRf Inverter 2 1 1 2 2 1 3 1 The SunPower SPRf inverter is now operational.

For determining the energy supplied to the grid, only the readings of the calibrated meter supplied by the electric utility company are relevant. Yield money earned during monitored period (set currency and price per kWh in setup menu) As was the case for the energy supplied, readings may differ from those of other instruments. CO2 reduction CO2 emissions avoided during monitored period (lb / T); T = tons The area for unit display switches between ‘lb’ and ‘CO2’. The CO2 meter gives an indication of CO2 emissions (in lb/t) that would be released during the generation of the same amount of electricity in a combustion power plant. This is set for 1.3 lb/kWh in the factory.

This enables you to know immediately if there are any malfunctions in the SunPower SPRf inverter, the photovoltaic system or any installation or operating errors. Whenever the self diagnostic system has identified a particular issue, the respective status code is shown on the screen. Important Display of a status code for a short time may be the result of the control procedures of your SunPower SPRf inverter. If it subsequently continues to operate normally, there has not been a system error. Normal operation status codes The open-circuit voltage of the solar modules is too low. As soon as the open-circuit voltage exceeds 290 V, the SunPower SPRf inverter starts synchronizing with the grid (display shows ‘SYNCAC’). The total power output of the solar modules is insufficient. After a short time the SunPower SPRf inverter resumes grid synchronization (display shows ‘SYNCAC’). Total failure If the display remains dark after sunrise: - Check the open-circuit voltage of the solar modules at the connections of the SunPower SPRf inverter: Open-circuit voltage < 290 V ... error in the photovoltaic system Open-circuit voltage > 290 V ... may indicate a basic fault in the SunPower SPRf inverter.
