20A PWM Solar Charge Controller 12V 24V, 5V Dual USB Solar Panel Battery Intelligent Regulator, for Lead-acid Batteries

The solar charging controller is only suitable for lead-acid batteries: such as OPEN, AGM, GEL

Charging current: 20A

USB output: maximum 5V/2A

Battery voltage: 12V/24V

If your battery is 12V, the maximum solar panel input is 25V 240W. If your battery is 24V, the maximum solar panel input is 50V 480W

UPGRADED SOLAR CONTROLLER: With the built-in industrial microcontroller, this PWM solar charge controller automatically helps you manage the working of solar panels and batteries in solar systems. When the battery runs out, it will memorize various parameters you set, so you don't need to reset it, which is easy and safe

WIDELY COMPATIBILITY IN BATTERY: The solar charge controller is compatible with 12V or 24V systems automatically, only suitable for lead-acid batteries, such as OPEN, AGM, and GEL. Dual USB 5V/3A output ports support mobiles, tablet PCs, or other devices that require 5V voltage. Please refer to the manual for more details. （NOTE: This PWM solar charge controller is NOT suitable for Lithium Battery.)

EASY TO READ AND ADJUSTABLE: Easily to read the status and data with an LCD display, which is also able to switch modes and parameter configuration, such as adjustment of battery float, reconnect, and stop discharge voltage, which can perfectly protect the battery from over-discharge, suitable for home, industrial, commercial, etc

SAFE TO USE: Built-in overcurrent protection, short circuit protection, reverse connection protection, open circuit protection, all automatic recovery, no damage to the solar controller, but a reliable protector for your devices and prolong the lifespan

EASY TO INSTALL AND OPERATE: The charge controller should connect the battery first, then the solar panel, and finally the load. The disassembly sequence is contrary to the wiring order. Please refer to the manual for details.
