Solar Charge Controller, 12V 8A PWM Solar Panel Battery Controller, Automatic Efficient Charging Solar Panel Battery Regulator with LCD Display.

LCD DISPLAY: This 12v solar charge controller has real-time display of charging current, battery power, battery voltage, solar indication, output indication, fault alarm, etc. You can visually see the working status and charging effect of the controller with this LCD display. DESIGN: This solar charge controller separates the three ports to help you to connect the cables easily and check your line clearly. The controller also has an output switch for you to manually control the output, which is easy and convenient to operate. PROTECTION: This solar charger controller features multiple protection functions, such as overload protection, short circuit protection, lightning protection, under voltage protection, over charge protection, reverse polarity protection. Please be especially careful when accessing solar panels, as the solar panels will burn out, if the wires are connected in reverse! INTELLIGENT & EFFICIENT CHARGING: This solar panel battery controller charge the battery efficiently and quickly by applying 3-stage PWM charging which combines bulk charge, absorption charge and float charge. It is equipped with industrial-grade STM 8 microprocessor that intelligently controls charging and discharging to extend the battery life. USB output interface provides a maximum current of DC5V 2.1A for your electronic devices. APPLICATION: Fit for 12V solar panel (20w-130w) with maximum current output of 8A (The current of solar panels below 20W is too low to use a controller.) Suitable for 12v rechargeable lead acid battery, with battery capacity from 12Ah to 100Ah：OPEN，AGM，GEL. Not suitable for lithium battery, Ni MH battery.
