ID001
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.

Charge Leakage Fault
Internal faults of inverter, switch OFF
inverter, wait for 5 minutes, then switch ON
inverter. Check whether the problem is
solved.
If no, please contact technical support.
