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. 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 grid overvoltage rapid
protection threshold after obtaining the
consent of the local power company if
the grid voltage is within the permissible
range.
4
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 breaker and the output
cables are connected securely and correctly if
the problem persists.
5
Grid 10min
Overvoltage
The moving average
of grid voltage in
10min exceeds the
range of safety
requirements.
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 grid overvoltage rapid
protection threshold after obtaining the
consent of the local power company if
the grid voltage is within the permissible
range.
