Li ion PWM Solar Charge Controller


20A PWM Solar Charge Controller


SSN PWM Charge Controller

SSN Digital Solar Charge Controller 20a 12/24v off grid for Li-ion




1. 12V/24V Automatic identification by system

2. LED digital display and one-key operation, easy to use

3. The improved 3-section computing method can weekly give the battery a

Balanced charging. It can stop the battery from being unbalancing and vulcanizing

and let the battery been used for more time.

4. the controller is equipped with the serial PWM charging main circuit with

additional 3%~6% efficiency than the non-PWM circuit which can work for more

time and increase the using period of the system.

5. Controller has three load work ways and can be easily used in varies streetlights

and monitors.

     6.Visualized LED display which can let the users get to know the conditions of

        solar power and storage battery.

 7. Overcharge, over discharge and overload protection; Electronic short circuit

protection; Reverse connect preventing protection.

  8. Lightning prevention.
