GT-CMP12 solar controller

3. The rated current of solar panels and loads are kept lower than the one of controller.

2. Pay more attention to + and - poles of solar panels, battery, controller and loads during the process of connection.

Their rated voltage should be 12v.

1. Please check the rated voltage of solar panels, battery, and load before conjunction.

Attention

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.

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.

1. Three red LEDs. They indicate the voltage of battery. It indicates the voltage enough that three red LEDs are all illumining.

Indicator light

3. Connect + and - poles of load with the correct ports on the controller (the fifth and sixth 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).

1. Connect+ and - poles of battery with the correct ports on the Controller (the third and fourth wires from the left).

 according to indication in the picture          

Connection

4. Prevent the battery from supplying power to solar panels during nights.

3. Prevent the battery from over-discharging.

2. Prevent the battery from over-charging.

1. Generally keep the battery on full voltage condition.

According to the voltage of battery, controller will adjust the charging current and decide if to supply power to the loads.

Function

According to the voltage of battery, controller will adjust the charging current and decide if to supply power to the loads.
