12V/24V 20A PWM Solar Charger Controller with USB

1.Three battery charging settings have been preset(B01Leadacid battery, B02Lithiumiron battery, B03Lithiumiron phosphate battery), according to the types of batteries, with power-off memor function, which can remember the settings when users power on next time.

2.Large-screen LCD display, charging and discharging parameters can be fully customized.

3.Adopt complete three phase PWM charge management(Constant current mode, constant voltage mode, floating charge mode.)

4.Built-in overcurrent/short circuit/open circuit and battery reverse protection.

5.Double MOS tube anti-reverse circuit protection, which prevents battery current from being caused power losstransferring to the solar cell at night.
