Solution
1. Check whether the
configured power meter
model is the same as the
actual model.
2. Check whether the
communications parameters
of the power meter are the
same as the RS485
configurations of the inverter.
3. Check whether the power
meter is powered on and
whether the RS485
communications cable is
connected.
Turn off the AC output switch
and DC input switch, and then
turn them on after 5 minutes. If
the alarm persists, replace the
monitoring board or contact
your dealer or Huawei technical
support.
1. If the voltage at the grid
connection point is too high,
contact the local power
operator.
2. If you have confirmed that
the voltage at the grid
connection point exceeds the
upper threshold and obtained
consent from the local power
operator, modify the
overvoltage protection
thresholds.
3. Check whether the peak grid
voltage exceeds the upper
threshold.
