● The output resistance of
PV arrays to ground is
low.
● The system insulation
resistance is low.
● Cause ID = 1
1. Turn o the AC output
switch and DC input
switch, wait for a period of
time (for details about the
wait time, see the
description on the device
safety warning label), and
then turn on the DC input
switch and AC output
switch.
2. If the alarm persists,
contact your dealer or
Huawei technical support.

1. Check the impedance
between the PV array
output and the ground. If
a short circuit occurs or
the insulation is
insucient, rectify the
fault.
2. If the alarm persists,
contact your dealer or
Huawei technical support.
