Installation Guide

In SolarEdge systems, due to the introduction of poweroptimizers 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 system’s string voltage and

current, refer to the

and I

in SolarEdge Systems Technical Note

available on the SolarEdge website at:

technical_note.pdf .

To verify proper power optimizer 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.
