5.3.3 Overcharge protection voltage (lithium battery)/boost voltage (other battery types)

protection voltage on the current screen.Setting range:12/24V:10.1~32.0V(default 14.4V)

1.When the battery type is lithium battery,you can set the lithium battery overcharge

2. When the battery type is AGM/GEL/LIQ , you can set the boost voltage on the current

voltage is ≈(0.97*overcharge protection voltage).

screen.The equalization

voltage is boost voltage +0.3V(12V system)/+0.6V(24V system).

The float

voltage is boost voltage -0.8V/1.6V.

Note: The GEL battery is not have equalization.

5.3.4 Low voltage protection

1.When the battery type is lithium battery,you can set the lithium battery low voltage

protection voltage on the current screen. Setting range：9.0~30.0V(default 10.6V)

Note: The controller automatically calculates the low-voltage recovery voltage

according to the set low-voltage protection voltage. The low-voltage recovery

voltage is ≈1.11* low-voltage protection voltage.

2. When the battery type is GEL/LIQ/AGM,

Setting range：10.8~11.8.V/21.6~23.6V(default 11.2/22.4V)

Note: The default low-voltage recovery voltage of the controller is 0.8V/1.6V

higher than the low-voltage protection voltage. To reduce the low-voltage

recovery voltage, lower the low-voltage protection voltage first.
