Troubleshooting Suggestion
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 voltage
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 overvoltage
protection threshold with the
consent of the local power
operator.
3. Check whether the peak
voltage of the power grid is
too high. If the fault persists
and cannot be rectified for a
long time, contact the power
operator.
