Troubleshooting
1. If the alarm occurs occasionally,
the power grid may be abnormal
temporarily. The SUN2000
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,
SmartLogger, or NMS with the
consent of the local power
operator.
