board is fault
ID55
RelayTestFail
The relays fault
ID56
PvIsoFault
The insulation
resistance is too low
Check the insulation resistance between the
PV array and earth(ground), if a short circuit
occurs, rectify the fault.
ID57
OverTempFault_
Inv
The inverter temp is
too high
Ensure the installation position and
installation method meet the requirements of
Section 3.4 of this user manual.
Check whether the ambient temperature of
the installation position exceeds the upper limit.
If yes, improve ventilation to decrease the
temperature.
