Troubleshooting Suggestions
1. Check whether the grid
connection voltage exceeds
the upper threshold. If yes,
contact the local power
operator.
2. If you have confirmed that
the grid-tied voltage
exceeds the upper
threshold and have
obtained the consent of the
local power operator,
modify the overvoltage
protection threshold
through the mobile app,
SmartLogger, or NMS.
3. Check whether the peak
grid voltage exceeds the
upper threshold.
1. Check that the grid voltage
is within the normal range.
2. Check that the AC output
power cable is correctly
connected. If the AC output
power cable is correctly
connected, yet the alarm
persists and affects the
energy yield of the power
plant, contact the local
power operator.
