setting parameters
4 Battery protect
During the discharge of the battery, when the
battery voltage is lower than the set value of the
‘battery protection’ parameter or the discharge
time exceeds the set value of the ‘ LVD2
protection time’ parameter, the battery protection
contactor will be automatically disconnected.

System
current
unbalanced
In the system with shunt, there exists great
difference between the collected load current plus
the battery current and the module output
current.
No alarm N/A

Output voltage
abnormal
The control output voltage is different from the
collected bus voltage, and different from the
reported data of the module. The error is larger
than 1V

15 AC power-cut
In the system with AC collection board:
All the AC voltages are lower than 80V.
Neither AC circuit 1 nor circuit 2 is in working
state.
In the system without AC collection board:
The AC input of all the rectifiers is cut off.
The AC input voltage of all the rectifiers is lower
than the ‘phase loss alarm’ threshold
