Step 4: Verifying Proper Power Optimizer Connection

In SolarEdge systems, due to the introduction of poweroptimizers between the PV modules and the

inverter, the short circuit current I

those in traditional systems.

For more information about the SolarEdge s ystem's string voltage and current, refer to

in SolarEdge Systems Technical Note, available on the SolarEdge website at:

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.

For troubleshooting power optimizer operation problems, refer to Power Optimizer Troubleshooting on
