New PWM Solar charge controller with four USB port 20A 12V 24V auto controller
This controller is suitable for solar power generation system. It is mainly used to protect battery, iron lithium battery, power battery, polymer lithium battery, to prevent overcharge of battery and overdischarge of the load.
The intelligent charging and discharging controller can effectively extend the service life of the battery and lithium battery and improve the system performance.
Main function:
1. controller can automatically identify system voltage and is fully compatible with 12V and 24V systems.
2. humanized LCD display and dual keypad man-machine interface.
3. complete controller parameter setting and modification;
4. high efficiency and intelligent PWM three stage charging mode;
5. the load control mode is optional, which can set the lighting time at night.
6. the controller has overpressure, short circuit, overload, over discharge and over charging automatic protection function.
7. accurate temperature compensation, automatically adjust the charging voltage according to the ambient temperature, and prolong the life of the battery.
8. complete anti - connection automatic protection function;
9. the product is designed in a positive way, and the power MOS tube is used to control the anode in series.
