Troubleshooting
1. If the alarm occurs
occasionally, 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 power grid
frequency is within the
allowed range. If no,
contact the local power
operator. If yes, modify
the grid overfrequency
protection threshold
through the mobile app,
or NMS with the
consent of the local
power operator.
