PWM Solar Charge Controller HP series 20A

Description

1. Automatic identification of 12V/24V system voltages.

2. An upgraded 3-stage PWM charging algorithm is adopted. Overdischarge or application of an equalizing charging to the battery regularly can effectively prevent the battery from non-equalization and sulfuration and extend the lifespan of battery.

3. Featuring a temperature compensation function, the controller can automatically adjust charging parameters.

4. A variety of load working modes which facilitate the product's application to different types of loads.

5. The product provides overcharge, overdischarge, overload protection, as well as short-circuit protection.

6. Advanced startup method of load: Large capacitance loads can be started smoothly.

7. The product adopts a dot-matrix graphic LCD screen and a human-machine interface with two switches.

8. The humanization design of interface ensures users can use the product conveniently.

9. With an industrial grade design, the product can function well in various tough situations.

10. TVS lightening protection is adopted.
