to Ground
Major Cause ID = 1
The voltage between the
input PV modules and the
ground is abnormal, and
there is a risk of power
degradation.
1. If the system does not
have PID compensation
devices, disable the PID
protection. Note that
enabling the reactive
power compensation at
night even when the PID
protection is disabled
brings risks of PV
module degradation.
2. If the system has a PID
compensation device,
check whether the
device is abnormal. If
yes, rectify the fault.
3. Check whether the
settings of
compensation direction
for the SUN2000 and
the PID device are
consistent. If not, set
them to be consistent
based on the PV module
model. (Note: If the PV–
is set to positive
oset,
the voltage between the
SUN2000 PV– and the
ground should be
greater than 0 V to clear
the alarms; if the PV+ is
set to negative
oset,
the voltage between the
SUN2000 PV+ and the
ground should be less
than 0 V to clear the
alarms.)
4. If the fault occurs
repeatedly, contact your
dealer or Huawei
technical support.
