Power grid exception: The
actual power grid
frequency is higher than
the requirements for the
local power grid code.
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 persists, 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 app,
SmartLogger, or NMS with
the consent of the local
power operator.
