ID56
PvIsoFault
The insulation
resistance is too low.
Check the insulation resistance
between the photovoltaic string and
the ground, in the event of a short
circuit, rectify the fault.
ID57
OverTempFault_Inv
The temperature of
the inverter is too
high.
Check that the installation position
and the installation method meet the
requirements of relative section of
this user manual.
Check if the ambient temperature in
the installation location exceeds the
allowed limit. If so, improve the
ventilation to reduce the temperature.
ID58
OverTempFault_Boost
The boost
temperature is too
high.
ID59
OverTempFault_Env
The ambient
temperature is too
high.
ID60
PEconnectFault
Incorrect grounding
Check that the grounding is correct.
ID61
InvTempDiffFault
The temperature
difference between the
three R/S/T phases is
greater than 10°C
Contact Technical Support
ID65
UnrecoverHwAcOCP
The grid current is
too high and has
caused an irreparable
hardware failure.
ID65-ID70 are internal faults of the
inverter; turn off the “DC switch”, wait
5 minutes and then turn it back on
again. Check that the fault is no longer
present. If this is not the case, contact
Technical Support.
ID66
UnrecoverBusOVP
The bus voltage is too
high and has caused
an irreparable fault.
ID67
UnrecoverIacRmsUnbalance
The grid current is
not balanced and has
caused an irreparable
fault.
ID68
UnrecoverIpvUnbalance
The input current is
not balanced and has
caused an irreparable
fault.
ID69
UnrecoverVbusUnbalance
The bus voltage is not
balanced and has
caused an irreparable
fault.
