Make sure the PV modules are exposed to sunlight during this process. The Power

Optimizer will only turn ON if the 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

hold different meanings from those in traditional systems.

For more information about the SolarEdge system's string voltage and

current, refer to the V

available on the SolarEdge website at:

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 Synergy Manager .

For troubleshooting Power Optimizer operation problems, refer to Power Optimizer

Troubleshooting on page 76.

Proper Power Optimizer connection can also be verified in the Designer application.
