Fault
Major
Abnormal external conditions
have triggered DC circuit
protection inside the
SUN2000. The possible causes
are as follows:

Reason ID = 3
The SUN2000 input is
suddenly disconnected, or
the shielded PV strings
result in a sharp change in
output power.

Reason ID = 9 or 11
The input energy of the
SUN2000 cannot be vented
quickly due to the sharp
change of grid voltage. As
a result, the internal
voltage increases.

Reason ID = 10
The internal control circuit
of the SUN2000 is unable
to keep up with changes
due to grid phase
imbalances.
a. The SUN2000 monitors its
external working conditions in
real time and automatically
reverts to normal operating status
after the fault is rectified.
b. If the alarm occurs repeatedly,
contact Huawei technical
support.
