The grid voltage exceeds
the higher threshold or the
high voltage duration has
lasted for more than the
value
specied by HVRT.
1. If the alarm occurs
accidentally, the power grid
may be abnormal
temporarily. The inverter
automatically recovers after
detecting that the power grid
becomes normal.
2. If the alarm occurs
frequently, check whether the
power grid voltage is within
the acceptable range. If no,
contact the local power
operator. If yes, log in to the
mobile app, SmartLogger, or
network management system
(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
rectied for a
long time, contact the power
grid operator.

Major Cause ID = 1
The dierence between
grid phase voltages
exceeds the upper
threshold.
1. If the alarm occurs
accidentally, the power grid
may be abnormal
temporarily. The inverter
automatically recovers after
detecting that the power grid
becomes normal.
2. If the alarm occurs
frequently, check whether the
power grid voltage is within
the acceptable range. If no,
contact the local power
operator.
3. If the fault persists for a long
time, check the connection of
the AC output power cables.
4. If the AC output power cables
are correctly connected, but
the alarm persists and
aects
the energy yield of the PV
plant, contact the local power
operator.
