Invert

Fault
Major
Abnormal external
conditions cause the
protection for the
inversion circuit inside
the SUN2000. The
possible causes are as
follows:

Reason ID = 4
The grid voltage
sharp reduced or
short-circuit,
resulting in the
inverter output
current is too large.

Reason ID = 13
The grid voltage
sharp reduced or
short-circuit,
resulting in the
inverter internal
voltage detection
circuit failure.

Reason ID = 14
The grid voltage
sharp reduced or
short-circuit,
resulting in
instantaneous output
current of the
inverter is too large.

Reason ID = 16
The DC current of
grid current exceeds
the allowable range.

Reason ID = 17
Grid voltage or
frequency is
abnormal.

Reason ID = 20
The inverter output
short-circuit led to a
sharp increase in
output current.
Reason ID = 4, 13, 14, 16, or
17
1. The SUN2000 detects its
external working
conditions in real time,
and therefore the
SUN2000 automatically
recovers to the normal
operating status after the
fault is rectified.
2. If the alarm occurs
repeatedly, contact
Huawei technical support.
Reason ID = 20
1. Check whether the
inverter output cable is
short-circuit.
2. If the alarm occurs
repeatedly, contact
Huawei technical support.
