Major
Cause ID = 1
The inverter detects that the
phase voltage exceeds the
transient AC overvoltage
protection threshold.
1. Check whether the grid
connection voltage exceeds the
upper threshold. If yes, contact
the local power operator.
2. If you have confirmed that the
grid-tied voltage exceeds the
upper threshold and have
obtained the consent of the local
power operator, modify the
overvoltage protection threshold
through the mobile phone app,
SmartLogger, or NMS.
3. Check whether the peak power
grid voltage exceeds the upper
threshold.
Contact your dealer or Huawei technical support if the measures listed in the Troubleshooting
Suggestion column have been taken but the fault persists.
