Grid Rapid
Overvoltage
The grid voltage is
abnormal or ultra-
high.
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 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.

Grid
Undervoltage
The grid voltage
is lower than the
permissible range,
or the duration of
low voltage exceeds
the requirement of
LVRT.
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. If the problem occurs frequently, check
whether the grid voltage is within the
permissible range.
• Contact the local power company if the
grid voltage exceeds the permissible
range.
• Modify the undervoltage protection
threshold, LVRT or disable the
undervoltage protection function after
obtaining the consent of the local
power company if the grid frequency is
within the permissible range.
3. Check whether the AC circuit breaker and
the output cables are connected securely
and correctly if the problem persists.
