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 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 overfrequency
protection threshold with the
consent of the local power
operator.
