The grid voltage exceeds the
upper threshold or the
overvoltage duration exceeds the
time that triggers high voltage
ride-through (HVRT).
1. Check whether the grid
connection voltage exceeds
the upper threshold. If yes,
contact the local power
operator.
2. If you have
conrmed that
the grid connection voltage
exceeds the upper
threshold and have
obtained the consent of
the local power operator,
modify the overvoltage
protection threshold.
3. Check whether the peak
grid voltage exceeds the
upper threshold.

Major Cause ID = 1
The dierence 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
aects the
