Fault
Issue 10 (2017-07-30)
Severity Causes
Major Abnormal external conditions
have triggered converter
circuit protection inside the
SUN2000. The possible causes
are as follows:
 Reason ID = 4
A sharp drop in grid
voltage or a short-circuit
has occurred, resulting in
high output current from
the SUN2000.
 Reason ID = 13
A sharp drop in grid
voltage or a short-circuit
has occurred, resulting in a
fault in the voltage check
circuit of the SUN2000.
 Reason ID = 14
A sharp drop in grid
voltage or a short-circuit
has occurred, resulting in
instantaneous high output
current from the SUN2000.

Reason ID = 16
The grid DC current
exceeds the allowed range.
 Reason ID = 17
The grid voltage or
frequency is abnormal.
 Reason ID = 20
The SUN2000 output
short-circuits, leading to a
sharp increase in output
current.
