Grid
Overvoltage
Major
Cause ID=1
The grid voltage is beyond
the upper threshold or the
overvoltage duration has
exceeded the time that
triggers HVRT.
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.

Grid Voltage
Imbalance
Major
Cause ID=1
The difference between
grid phase voltages
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.
