Function
According to the voltage of battery, controller will adjust the charging current and decide if to supply power to the loads.
1. Generally keep the battery on full voltage condition.
2. Prevent the battery from over-charging.
3. Prevent the battery from over-discharging.
4. Prevent the battery from supplying power to solar panels during nights.
Connection
according to indication in the picture
1. Connect+ and - poles of battery with the correct ports on the Controller (the third and fourth wires from the left).
2. Connect + and -poles of solar panels with the correct ports on the controller (the first and second wires from the left).
3. Connect + and - poles of load with the correct ports on the controller (the fifth and sixth wires from the left).
Indicator light
1. Three red LEDs. They indicate the voltage of battery. It indicates the voltage enough that three red LEDs are all illumining.
2. One green LED. The battery is strongly charged when this light is illumining, the battery is floatingly charged when this LED is flickering, and the battery has stopped charging when the LED unlighted.
3. The voltage of battery is little low when one red LEDs or two red LEDs are illumining, maybe the load cant naturally work. But when the voltage of battery reaches 12.6v, the load will be allowed automatically to start work.
Attention
1. Please check the rated voltage of solar panels, battery, and load before conjunction.
Their rated voltage should be 12v.
2. Pay more attention to + and - poles of solar panels, battery, controller and loads during the process of connection.
3. The rated current of solar panels and loads are kept lower than the one of controller.
