GridOVP
The grid voltage is too
high
If the alarm occurs occasionally, the
possible cause is that the electric grid
is abnormal occasionally. Inverter will
automatically
return
to
normal
operating status when the electric
grid’s back to normal.
If the alarm occurs frequently, check
whether the grid voltage/frequency is
within the acceptable range. If yes,
please check the AC circuit breaker
and AC wiring of the inverter.
If the grid voltage/frequency is NOT
within the acceptable range and AC
wiring is correct, but the alarm occurs
repeatedly, contact technical support
to change the grid over-voltage,
under-voltage,
over-frequency,
under-frequency protection points
after obtaining approval from the local
electrical grid operator.
