ID001
GridOVP
The voltage of the
power grid is too
high
If the alarm occurs
occasionally, it may be
due to the power grid. The
inverter will automatically
return to normal operation
when the mains power
returns to normal.
If the alarm occurs
frequently, check whether
the mains
voltage/frequency is
within the permissible
range. If so, check the AC
circuit breaker and AC
wiring of the inverter.
If the alarm occurs
repeatedly, contact
technical support to
adjust the voltage and
frequency limits after
obtaining approval from
the local power grid
operator.
