20A PWM 12/24V Solar Charge Controller with LCD Display

20A 12/24V PWM Solar Charge Controller with LCD Display 1. 12V/ 24 V system voltages are automatically recognized. 2. An upgraded 3-stage PWM charging algorithm is adopted. Application of an equalizing charging to the battery periodically or when over discharged, can effectively prevent the battery from non-equalization and sulfuration, thus extending the battery’s service life. 3. With temperature compensation employed, charging parameters can be automatically adjusted. 4. A wide range of load working modes facilitate the product’s application to different types of load. 5. The product provides overcharge, over-discharge, overload protection, as well as shortcircuit protection. 6. By virtue of an advanced load starting method, large-capacitance loads can be started smoothly. 7. The product provides a dot matrix graphic LCD screen and a human-machine interface with a key.
