Alarm Cause
Severity
Major Cause ID = 1
The voltage between the
input PV string and the
ground is abnormal, and
there is a risk of power
attenuation.
Major Cause ID = 1
The impedance of the
output phase wire to PE is
low or the output phase
wire is short-circuited to
PE.
Major Cause ID = 1
1. The power grid
experiences an outage.
2. The AC circuit is
disconnected or AC
switch is off.

8 Maintenance
Measures
1. If no PID
compensation device
exists in the system,
disable the PID
protection function at
night, which will
cause PV module
attenuation if the
reactive power output
function at night is
enabled for the
inverter.
2. If there is a PID
compensation device
in the system, check
whether it is faulty. If
so, rectify the fault.
3. Check whether the
compensation
direction settings of
the inverter and the
PID compensation
device are the same.
If not, set the
parameters based on
the PV module type
and ensure that they
are the same.
4. If the alarm persists,
contact Huawei
technical support.
Check the impedance of
the output phase wire to
PE, locate the position
with lower impedance,
and rectify the fault.
1. The alarm disappears
automatically after
the power grid
recovers.
2. Check that the AC
power cable is
connected and that
the AC switch is ON.
