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.
