2. Check if the grid voltage is running at
a high voltage for a long time. If it
occurs frequently, please check if the
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.

1. If the problem occurs occasionally, the
utility grid may be abnormal

automatically after detecting that the
utility grid is normal.
2. If the problem occurs frequently,
check whether the grid frequency is
within the permissible range.
 Contact the local power company
if the grid frequency exceeds the
permissible range.
 Modify the overfrequency

overfrequency protection function
after obtaining the consent of the
