2. Diagnosing from the network:
a. No-Data-Display: The website and APP don't display any data.Check the network
configuration.
b. Only display microinverter is online but no data.This maybe because server is
updating.
To troubleshoot a non-operating Microinverter, Follow the steps
below in order:
1. Verify the utility voltage and frequency are within ranges shown in the Technical Data
section of this manual.
2. Check the connection to the utility grid.Disconnect AC firstly,then disconnect DC and
make sure the utility grid voltage can be measured at AC connector. Never disconnect
the DC wires while the microinverter is producing power. Re-connect the DC module
connectors and watch for three 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 breaker 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 shown in the Technical
Data of this manual.
7. If the problem still persists, please contact technical support.
WARNING
:
Do not attempt to repair the microinverter.If troubleshooting methods fail,
please call for Technical Support
