t Overhigh
Major
Cause ID = 1
The DC component of the
SUN2000L output current
exceeds the specified upper
threshold.
1. The SUN2000L monitors its
external working conditions in
real time. The SUN2000L
automatically recovers after the
fault is rectified.
2. If the alarm occurs frequently,
contact your dealer.

Abnormal
Residual
Current
Major
Cause ID = 1
The insulation impedance of
the input side to PE decreases
when the SUN2000L is
operating.
1. If the alarm occurs accidentally,
the external power cable may be
abnormal temporarily. The
SUN2000L automatically
recovers after the fault is
rectified.
2. If the alarm occurs frequently or
persists, check that the impedance
between the PV string and ground
is not below the lower threshold.
2061
Abnormal
Grounding
Major
Cause ID = 1

The protective earthing
(PE) cable for the
SUN2000L is not
connected.

The voltage between the
SUN2000L neutral wire
and ground exceeds the
upper threshold.
1. Check that the PE cable for the
SUN2000L is connected
properly.
2. Check that the voltage between
the SUN2000L neutral wire and
ground is within the normal
range. If an isolation transformer
is connected, set OFF due to
abnormal grounding to Disable
by referring to 7.4.5.3 Feature
parameters.
2062
Low
Insulation
Resistance
Major
Cause ID = 1

The PV string is
short-circuited to PE.

The PV string is installed in
a moist environment for a
long time.
1. Check the impedance between
the PV array output and PE, and
eliminate short circuits and poor
insulation points.
2. Check that the SUN2000L PE
cable 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.
2063
Overtempe
rature
Major
Cause ID = 1

The SUN2000L is installed
in a place with poor
ventilation.

The ambient temperature
exceeds the upper
threshold.

The SUN2000L is not
working properly.
1. Check the ventilation and
ambient temperature at the
SUN2000L installation position.
2. If the ventilation is poor or the
ambient temperature exceeds the
upper threshold, improve the
ventilation and heat dissipation.
3. If the ventilation and ambient
temperature both meet
requirements, contact your dealer.
