Alarm Cause
Severity
Major Cause ID = 1
1. The PV string is short-
circuited to PE.
2. The PV string has been
in a moist environment
for a long time and the
power cable is not well
insulated to ground.
Minor Cause ID = 1
1. The SUN2000 is
installed in a place with
poor ventilation.
2. The ambient
temperature exceeds
the upper threshold.
3. The SUN2000 is not
working properly.
Major Cause ID = 1–15

Measures
1. Check the impedance
between the PV string
and the PE cable. If a
short circuit occurs,
rectify the fault.
2. Check that the PE
cable for the
SUN2000 is correctly
connected.
3. If you are sure that
the impedance is less
than the default value
in a cloudy or rainy
environment, reset
Insulation resistance
protection.
1. Check the ventilation
and ambient
temperature at the
SUN2000 installation
position. If the
ventilation is poor or
the ambient
temperature exceeds
the upper threshold,
improve the
ventilation and heat
dissipation.
2. If the ventilation and
ambient temperature
both meet
requirements, contact
Huawei technical
support.
Turn off the AC output
switch and DC input
switch, and then turn
them on after 15
minutes. If the fault
persists, contact Huawei
technical support.
NOTE
Cause ID = 1: Perform the
preceding operations when
the PV string current is less
than 1 A.
