8.3 Under Voltage Lockout (LVD)
8.4 Low Voltage Reclosing (LVR)
If the undervoltage lockout is triggered, the controller will not reestablish the charge
connection until the battery voltage is above the LVR voltage.

The LVR should be higher than the LVD.
SoC 1
2. Gel, wet and AGM batteries:
The LVD should be at least 0.6V.
11.4-11.9V
1. Lithium batteries: LVD=9.0-15.0V (default: 9.0V)
11.6 - 12.0V
1. Lithium batteries: LVR= 9.6 to 16.0 V 2.
Gel, wet and AGM batteries: LVR= 11.4 to 12.8 V

SoC 3
If you want to change the LVD, you must first change the LVR.
The low voltage protection of the controller can be divided into two types: a. Battery voltage control:
Low voltage cut-off adjustment range: 10.8-11.8V (default: 11.2V) b. Battery capacity control:
Setting range of undervoltage shutdown: SoC 1 – SoC 5
SoC 2
11.0 - 11.6V
SoC 5

SoC 4
11.2 - 11.8V
To prevent deep discharge of the load, the controller turns off the load as soon as the battery voltage
falls below the LVD voltage. Should this happen, the battery must be fully charged before using it
again.
