Troubleshooting Suggestions
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 acceptable
range. If not, contact the
local power operator. If yes,
modify the grid
overfrequency protection
threshold through the
mobile app, SmartLogger,
or NMS with the consent of
the local power operator.
