DescriptionThis Solar Battery Charge Controller automatically manages and regulates the voltage and current going into the battery from the solar panel, and it's designed with over-current, open-circuit, short circuit, anti-reverse protection in order to ensure that the batteries are not overcharged.Features- Color: Black- Size: 13.2x6.9x3cm/5.1x2.7x1.1inch- Material: ABS- LCD display, can adjust charging or discharging settings.- Over-current, open-circuit, short circuit, anti-reverse protection and other fully automatic controllers: the above protection does not damage any components, and does not burn insurance.- Adopting PWM charging main circuit so that the voltage loss of the charging circuit is lower than that of the charging circuit using diodes.- Double mos anti-reverse circuit, low heat productivity- Note: can only charge lead-acid cell. Specification- Rated voltage: 12V or 24V current 30A- Pv voltage: <50V- Floating voltage: 13.7V / 27.4V- Cut-off voltage: 10.7V/21.4V- Discharge recovery voltage: 12.6V/25.2V- USB Output: 5V 3A- Working temperature: -35 ℃-+ 60 ℃Package Including1 x 30A Solar Charge Controller with LCD Display Solar Panel Charge Controller 12V 24V Dual USB Charge Regulator (30A)
