12/24V 30A Solar Panel Lithium Ion Battery PWM Regulator Charge Controller with USB Outputs

This PWM Solar Battery Charge Controller automatically manages and regulates the voltage and current to lead-acid, lithium-ion, and lithium iron phosphate (LiFePO4) batteries from the solar panel(s). It incorporates short-circuit, open-circuit, reverse polarity, and overload protection in order to ensure that the batteries are not overcharged and that power isn't discharged from the batteries to the solar panels during shaded or dark conditions and drain the batteries. It comes with USB ports to charge for your phone and other electronic devices directly from the controller. This solar charge controller is perfect for smaller homes, cabins, RVs, and other remote and portable solar systems. Features This controller is designed for use with 3-string (11.1V) Lithium-Ion, 4-string (12.8V) Lithium Iron Phosphate (LiFePO4), or 12V and 24V lead-acid batteries.  Regulates the voltage from the solar panels going to the batteries. Built-in industrial master chip to control the charge and discha
