    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.

    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.

  • Page 15: Step 1: Mounting The Power Optimizers

    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 ...

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...

WARNING! Input and output connectors are not watertight until mated. Open connectors should be mated to each other or plugged with appropriate watertight caps.

  • Page 18: Step 4: Verifying Proper Power Optimizer Connection

    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.

    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) <...
