Solutions
1. If the problem occurs occasionally,
the utility grid may be abnormal
temporarily. The inverter will recover
automatically after detecting that the
utility grid is normal.
2. Check if the power grid voltage has
been operating at a high voltage for
a long time. If it occurs frequently,
please check if the power grid voltage
is within the allowable 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.
