20A PWM Solar Charge Controller with 12V/24V Adaptive Input Below 55V for Solar Panels, Suitable for Gel Batteries, with LCD Display, Temperature Compensation, and Multiple Protections

<ul><li>Automatic identification for system voltage: 12V/ 24V.</li><li>5 working modes (light control/ light control + time control/ manual mode/ debugging mode/ normal on) facilitate the product's application to different types of load, such as streets lights and monitoring devices.</li><li>An upgraded 3-stage PWM charging algorithm is adopted. Application of an equalizing charge to the battery periodically or when over discharged, can effectively prevent the battery from non-equalization and sulfration, thus extending its service life.</li></ul>
