Issue 04 (2019-06-30)
Alarm Cause
Severity
1. The PV string has been
Warning
shaded for a long time.
2. The PV string deteriorates
abnormally.
Cause IDs 1 to 12 respectively
correspond to PV strings 1 to
12.
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.

Measures
1. Check whether the
current of the abnormal
PV string is lower than
the current of other PV
strings. If yes, check that
the abnormal PV string is
not shaded and the actual
number of PV strings is
the same as the
configured number.
2. If the abnormal PV string
is clean and not shaded,
check whether the PV
string is damaged.
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.
