Product Details

pwm solar charge controller 20A 12V 24V

1. Intuitionistic LED indicators show the current system battery capacity, charging and discharging state of the battery.

2. Having the protection functions as overcharging, over discharging, overload, short-circuit and reversed connection.

3. Tandem type PWM charging makes the charging efficiency increase by 3% to 6%, compared with non-PWM charging.

4. The parameters of charging and discharging have been set during the production (special parameters need to be told in advance), so no need to adjust the parameters.

5. It can set the working mode of the load.
