NOTE A SolarEdge inverter may be installed in a site with a generator, however must not operate at the same time as the generator. Operating an inverter and a generator simultaneously will void the warranty. SolarEdge requires installing a physical or electronic interlock, which will prevent the generator and inverter from operating simultaneously.
Chapter 1: Introducing the SolarEdge Power Harvesting System Chapter 1: Introducing the SolarEdge Power Harvesting System The SolarEdge power harvesting solution is designed to maximize the power output from any type of solar Photovoltaic (PV) installation while reducing the average cost per watt. The following sections describe each of the system’s components. Figure 1: The SolarEdge power harvesting system components SolarEdge Power Optimizer The SolarEdge power optimizers are DC-DC converters connected to PV modules in order to maximize power harvesting by performing independent Maximum Power Point Tracking (MPPT) at the module level. The power optimizers regulate the string voltage at a constant level, regardless of string length and environmental conditions. The power optimizers include a safety voltage function that automatically reduces the output of each power optimizer to 1 Vdc in the following cases: ...
Extended Power Commercial Inverter Extended Power Commercial Inverter The extended power commercial inverter ( referred to as 'inverter' in this manual ) efficiently converts DC power from the modules into AC power that can be fed into the main AC service of the site and from there to the grid. The inverter also receives the monitoring data from each power optimizer and transmits it to the SolarEdge monitoring platform (requires Internet or Cellular connection). The inverter i s comprised of one Primary Unit with an integrated Connection Unit w ith a DC Safety Switch (referred to as 'Connection Unit ' in this manual) for disconnecting the DC power of a SolarEdge system, and of o ne or two Secondary Units, depending on the inverter's capacity. The Secondary Unit(s) are connected to the primary unit with AC, DC and communication cables. Each unit operates independently and continues to work in case the others are not operating. You can set up a master- slave configuration, connecting up to 31 additional inverters to one master inverter.

Chapter 1: Introducing the SolarEdge Power Harvesting System SolarEdge Monitoring Platform The SolarEdge monitoring platform enables monitoring the technical and financial performance of one or more SolarEdge sites. It provides past and present information on the system performance both at the system and module levels. Installation Procedure The following is the procedure for installing and setting up a new SolarEdge site. Many of these also apply to modification of an existing site. 1. Installing the Power Optimizers, page 13 2. Mounting and Connecting the Primary and Secondary Unit(s), page 23 NOTE It is recommended to connect communication connections (step 6 of this installation) before connecting the AC, for easier access to the communication board.

PV modules. IMPORTANT SAFETY FEATURE Modules with SolarEdge power optimizers are safe. They carry only a low safety voltage before the inverter is turned ON. As long as the power optimizers are not connected to the inverter or the inverter is turned OFF, each power optimizer will output a safe voltage of 1V.
Step 1: Mounting the Power Optimizers The steps in this chapter refer to module add-on power optimizers. For smart modules, start from Step 3: Connecting Power Optimizers in Strings on page 15 . Also refer to the documentation supplied with the smart modules. The power optimizer can be placed in any orientation. If connecting more modules than optimizer inputs in parallel, use a branch cable (available from SolarEdge). Some commercial power optimizer models h ave a dual input . Position the power optimizer close enough to its module so that their cables can be connected. Make sure to use power optimizers that have the required output conductor length: Minimize the use of extensions between power optimizers, and use only if connection between optimizers in different rows or arrays is required. Do not use extension cables between the modules and the power optimizers. The minimum and maximum string length guidelines are stated in the power optimizer datasheets. Refer to the SolarEdge Site Designer for string length verification. The SolarEdge Site Designer is available on the SolarEdge website at http://www.solaredge.com/products/installer-tools/site- designer#/. Completely shaded modules may cause their power optimizers to temporarily shut down. This will not affect the performance of the other power optimizers in the string, as long as the minimum number of unshaded power optimizers connected in a string of modules is met. If under typical conditions fewer than the minimum optimizers are connected to unshaded modules, add more optimizers to the string. T o allow for heat dissipation, maintain a 2.5 cm / 1" clearance distance between the power optimizer ...
Figure 4: Power optimizer connectors Step 3: Connecting Power Optimizers in Strings You can construct parallel strings of unequal length, that is, the number of power optimizers in each string does not have to be the same. The minimum and maximum string lengths are specified in the power optimizer datasheets. Refer to the SolarEdge Site Designer for string length verification. NOTE Use at least 11 AWG/ 4 mm² DC cables. The total conductor length of the string (excluding power optimizers’ conductors; including home runs and necessary extensions between optimizers) should not exceed: 2300 ft./ 700 m from DC+ to DC- of the inverter...
Page 17
1. Connect the Minus (-) output connector of the string’s first power optimizer to the Plus (+) output connector of the string’s second power optimizer. 2. Connect the rest of the power optimizers in the string in the same manner. Figure 5: Power optimizers connected in series 3. If you intend to monitor the installation, using the SolarEdge monitoring platform, record the physical location of each power optimizer, as described in Providing Installation Information on page 45. WARNING! Input and output connectors are not watertight until mated. Open connectors should be mated to each other or plugged with appropriate watertight caps.
Connection When a module is connected to a power optimizer, the power optimizer outputs a safe voltage of 1V. Therefore, the total string voltage should equal 1V times the number of power optimizers connected in series in the string. For example, if 10 power optimizers are connected in a string, then 10V should be produced. Make sure the PV modules are exposed to sunlight during this process. The power optimizer will only t urn ON if t he PV module provides at least 2W. In SolarEdge systems, due to the introduction of power optimizers between the PV modules and the inverter, the short circuit current I and the open circuit voltage V hold different meanings from those in traditional systems. For more information about the SolarEdge s ystem’s string voltage and current, refer to the V and I in SolarEdge Systems Technical Note, available on the SolarEdge website at: http://www.solaredge.com/files/pdfs/isc_and_voc_in_solaredge_systems_technical_ note.pdf . To verify proper power optimizers connection: Measure the voltage of each string individually before connecting it to the other strings or to the inverter. Verify correct polarity by measuring the string polarity with a voltmeter. Use a voltmeter with at least 0.1V measurement accuracy. NOTE Since the inverter is not yet operating, you may measure the string voltage and verify correct polarity on the DC wires inside the Connection Unit.

Chapter 4: Connecting the AC and Strings to the Connection Unit Selecting a Residual Current Device (RCD) IMPORTANT SAFETY FEATURE All SolarEdge inverters incorporate a certified internal Residual Current Device (RCD) in order to protect against possible electrocution and fire hazard in case of a malfunction in the PV array, cables or inverter. There are 2 trip thresholds for the RCD as required for certification (DIN VDE 0126-1-1). The default value for electrocution protection is 30 mA per unit , and for slow rising current is 300 mA per unit. If an external RCD is required by local regulations, check which type of RCD is required for the relevant electric code. Install the residual-current device (RCD) in accordance with the applicable local standards and directives. SolarEdge recommends using a type A RCD. When required by local regulations, the use of an RCD type B is permitted. Use at least 600mA RCD for a 2 unit inverter and at least 900mA RCD for a 3 unit inverter. NOTE For multiple inverters, an RCD per inverter is required. You have completed installing the system, proceed to the next chapter to activate and commission it, ...

Appendix C: SafeDC™ Appendix C: SafeDC™ When AC supply to the inverter is shut off (by shutting off the AC breaker at the site), or when the inverter ON/OFF/P switch is turned to OFF, the DC voltage drops to a safe voltage of 1V per optimizer. The SolarEdge inverters are certified for compliance with the following standards as disconnection devices for PV generators, meaning that they can replace a DC disconnect: IEC 60947-3:1999 + Corrigendum: 1999 + A1:2001 + Corrigendum 1:2001 + A2:2005; DIN EN 60947-3 VDE 0660-107:2006-03 IEC 60364-7-712:2002-05 DIN VDE 0100-712:2006-06. In compliance with these standards, the disconnection mechanism operates as follows: 1. Turn the inverter ON/OFF/P switch, located at the bottom of the inverter, to OFF, or disconnect the AC by shutting off the AC breaker at the site. The DC voltage displayed on the inverter LCD begins to decrease. If the AC breaker was shut off, the LCD does not display. In this case, wait five minutes. 2. When the DC voltage reaches a safe voltage, the PV connectors at the input to the inverter can be disconnected. A galvanic separation then exists between the PV array and the inverter. WARNING! SafeDC complies with IEC60947-3 when installing the system with a worst case SafeDC voltage (under fault conditions) <...
