Possible solution
ID01
GridOVP
The grid voltage is too
high.
If the alarm occurs occasionally, the
probable cause is that the electric grid
is in an abnormal state.
The inverter will automatically return
to its normal operating state when the
electrical grid is restored to its
normal state.
If the alarm occurs frequently, check
whether the grid voltage/frequency is
within the correct range. If not,
contact technical support. If so, check
ID02
GridUVP
The grid voltage is too
low.
ID03
GridOFP
The grid frequency is
too high.
