7.5 On-site Inspection (For qualified installers only)
To troubleshoot an inoperable microinverter, follow the steps in the order shown.
1.
Verify the utility voltage/frequency are within ranges as shown in the technical data.
2.
Check the connection to the utility grid. Verify utility power is present at the inverter in question by removing AC, then
DC power. Never disconnect the DC wires while the microinverter is producing power. Re-connect the DC module
connectors and watch for five short LED flashes.
3.
Check the AC branch circuit interconnection between all the microinverters. Verify each inverter is energized by the
utility grid as described in the previous step.
4.
Make sure that any AC breakers are functioning properly and are closed.
5.
Check the DC connections between the microinverter and the PV module.
6.
Verify the PV module DC voltage is within the allowable range as shown in the technical data.
7.
If the problem persists, please call Power Center customer support.
