CMG2420

LCD solar charge controller

PDF File: CMG2420 controller
Product overview
1. With LCD to display all parameters, the LCD has rich contents, the users can intuitively know the working condition of the controller.
2. With built-in energy-saving backlight LCD, display better and more power-efficient.
3. With SMPS DC12V and USB 5V stabilized voltage output, available for DC lamp and phone charging.
4. With output switch, intelligent control, easy to operate;
5. The system power adopts switching mode power supply which can reduce the quiescent current.
5. With separated temperature detected circuit, with high precision temperature compensation function.
7. With exposed terminals, the wiring more convenient, what’s more, the CMF series with metal shell.
8. Use single-chip microcomputer control which makes the controller has the advantages of intelligent, strong adaptability, reliable function.
9. Use PWM upgrade control scheme to WPC mode, which can improve system efficiency and prolong the life span of the battery.
Installation Instructions
Open the top cover of controller and connect the wire with terminals as the diagram on the top cover of it.

1.Connect the “+”, “-” Poles of the battery to the corresponding ports of controller (the third and the fourth one from left).

2.Connect the “+”, “-” poles of the solar panel to the corresponding ports of controller (the first and the second one from left).

3. Connect the “+”, “-” poles of the load to the corresponding ports of controller (the fifth and the sixth one from left).
Note: If there is connection error, it may damage your controller.
