Please make sure WKS I inverter is installed in a
place without direct sunlight.
Please make sure WKS I inverter is installed in a
cool / well-ventilated place.
Make sure the inverter is vertically installed & the
ambient temperature is less than the temperature
upper limit of WKS I inverter
ID58
OverTempFault_
HeatSink
The temperature of heat
sink is too high
ID59 OverTempFault_Env

too high
ID60
PE connectFault
Check the grounding of AC output PE wire.
ID65 unrecoverHwAcOCP
The grid current is too high
and has cause unrecoverable
hardware fault
ID65-ID67 are internal faults of WKS I inverter,
switch OFF WKS I inverter, wait for 5 minutes,
then switch ON WKS I inverter. Check whether
the problem is solved.
If no, please contact WATTUNEED technical support.
ID66 unrecoverBusOVP
The bus voltage is too high
and has cause unrecoverable
fault
ID67
