Description

CMP*2 solar charge controllers are able to adjust the charge current and decide if to supply the loads electricity according to the voltage of battery. CMP*2 solar charge controllers are used for solar home system or portable solar home system. Functionï&frac*4;�According to the voltage of battery, Solar charge 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. Connectionï&frac*4;� As indicated in diagram: 1. Connect â�� â�� and â��-â�� poles of solar panels with the correct ports on the controller (the first and second from the left). 2. Connectâ�� â�� and â��-â�� poles of battery with the correct ports on the controller (the third and fourth from the left). 3. Connect â�� â�� and â��-â�� poles of load with the correct ports on the controller (the fifth and sixth from the left). Indicator lightï&frac*4;� 1. There are 3 red LEDs indicating the voltage level of battery. The battery is full when all 3 LEDs are lighting. When 1 or 2 LEDs are lighting, it means the battery is on the low level, where the loads may not working properly. As the voltage of battery reaches *2.6, the loads will automatically resume working. 2. The battery is being strongly charged when the â��Charge LEDâ�� is lighting. The battery is floatingly charged when this LED is flickering, and the battery has stopped charging when the LED is off. 3. The â��Load LEDâ�� indicates the working condition of loads. When it lights, it means the load may work; when itâ��s off, it means the load may not work. Noticeï&frac*4;� 1. Please check the rated voltage of solar panels, battery, and load before connecting. Their rated voltage should be same (*2v). 2. Pay more attention to â�� â�� and â��-â�� poles of solar panels, battery, controller and loads during the process of connection. 3. The rated current of solar panels and loads must be less than the one of controller.
