The grid voltage is
abnormal or ultra-
high.

utility grid may be abnormal temporarily.
The inverter will recover automatically
after detecting that the utility grid is

2. Check whether the high grid voltage
continues for a long time. If the problem
occurs frequently, check whether the grid
voltage is within the allowed range.
Contact the local power company if the
grid voltage exceeds the permissible
range.
Modify the grid overvoltage rapid
protection threshold after obtaining
the consent of the local power
company if the grid voltage is within
the permissible range.
