Description
PV generator leakage to ground or input
surge voltage protections have activated
The leakage current
conductor is too high
The measured grid data is outside of the
required specification (voltage & frequency)

(See " " in appendix)
1. The grid impedance is higher than the
permissible value
2. The grid impedance change (ΔZ) is
higher than the maximum limit
The utility is not available
The input voltage is higher than "Max open
DCV"
The readings of output AC voltage,
frequency, leakage, DC current injection are
not consistent
