Battery SOC display
OK (Yellow LED off)
When the battery voltage is indicated as low, it is recommended to use the remaining
energy economically. The charge controller will subsequently switch off the load.
Load status display
In case of deep discharge or overload/short-circuit of load, the load output is switched
off. This is indicated by:
Normal operation
(Red LED off)
Low Voltage Disconnect Function
The charge controller is equipped with a low voltage disconnection function to protect
the battery against a deep discharge: This function is controlled by the voltage, and
automatically switches off the load output at a battery voltage lower than 11.0 V. As
soon as the battery reaches a voltage of 12.8 V, the load output is switched on again.
