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
SC
and the open circuit voltage V
OC
hold different meanings from those in traditional systems.
For more information about the SolarEdge system’s string voltage and
current, refer to the V
OC
and I
SC

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.
