Troubleshooting Suggestion
1. If the alarm occurs
accidentally, the power grid
may be abnormal
temporarily. The inverter
automatically recovers after
detecting that the power grid
becomes normal.
2. If the alarm occurs
frequently, check whether the
grid frequency is within the
acceptable range. If no,
contact the local power
operator. If yes, log in to the
mobile phone app,
SmartLogger, or NMS to
modify the grid
underfrequency protection
threshold with the consent of
the local power operator.
