SolarEdge SE Series User Manual

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 DC Safety Unit.
For troubleshooting power optimizer operation problems, refer to Power Optimizer
Troubleshooting on page 62.
Proper power optimizer connection can also be verified in the Designer application.
For more information, refer to

Step 5: Connecting the Strings to a
Combiner Box
For connecting the strings to the DC safety Unit with glands using a single input
connection use a combiner box. The combiner box should reside between the modules
and the inverter.
For the procedure see Connecting PV Strings to the DC Safety Unit with Glands on page
37.
