Recommended solutions:
1. Restart inverter by turning both AC and DC switches OFF. Wait for 1
minute for all energy to discharge and turn both switches ON.
2. If inverter cannot clear fault, contact Technical Support.
Recommended solutions:
1. Restart inverter by turning both AC and DC switches OFF. Wait for 1
minute for all energy to discharge and turn both switches ON.
2. If inverter cannot clear fault, replace inverter.
Recommended solutions:
Check wires of PV and ground.
1. Turn OFF AC switch to disconnect inverter from grid.
2. Open fuse holders to isolate PV strings. Test strings with meter.
3. Add one PV string and start inverter to see if alarm occurs.
4. If no alarm, turn OFF AC switches to disconnect from grid and add
in the next string. Start inverter again.
5. Continue until the string that triggers the alarm is identified. Trace
back the faulted string to find any leakage to Earth Ground.
Recommended solutions:
1. Restart inverter by turning both AC and DC switches OFF. Wait for 1
minute for all energy to discharge and turn both switches ON.
2. If inverter cannot clear fault, replace inverter.
Recommended solutions:
1. Raise limit of IDCmax (for example, 400mA) to allow inverter
more room to adjust in transient condition to cope with
imbalance of impedance and voltage between grid phases.
2. If alarm still occurs after adjustment, replace inverter.
