PROTECTION
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.
