Alarm Causes
Severity
Major Abnormal external conditions
have triggered the protection
for the converter circuit inside
the SUN2000. The possible
causes are as follows:
 Reason ID = 4
The grid voltage sharply
drops or short-circuits,
resulting in high output
current of the SUN2000.
 Reason ID = 13
The grid voltage sharply
drops or short-circuits,
resulting in a fault in the
voltage check circuit of the
SUN2000.
 Reason ID = 14
The grid voltage sharply
drops or short-circuits,
resulting in instantaneous
high output current of the
SUN2000.
 Reason ID = 16
The DC current of grid
current exceeds the
allowable range.
 Reason ID = 17
The grid voltage or
frequency is abnormal.
 Reason ID = 20
The SUN2000 output
short-circuit leads to a
sharp increase in output
current.

Measures
Reason ID = 4, 13, 14, 16, or 17
1. The SUN2000 monitors its
external working conditions in
real time and 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 SUN2000
output cables are short-circuited.
Rectify any fault.
2. If the alarm occurs repeatedly,
contact Huawei technical
support.
