20A Solar Charge Controller 12V/24V Auto, Solar Panel Charge Controller 20Amp Solar Regulator Lithium Battery/Lead-Acid with Dual USB LCD, Adjustable Parameter Backlight LCD Display and Timer Setting

Key features

• ☀☀☀Solar charge Controller with dual USB ports, USB Output: 5V/2A max. Battery voltage: 12V/24V auto; Rated Charge & Discharge Current: 20A; Settable operating modes of loads, Adjustable power rate with dual USB ports; 4-Stage(Boost, ABS, Equalization, Float).
• ☀☀☀This solar charger controller equipped with industrial-grade STM 8 microprocessor to control the charger and discharge process.the power MOSFET is used as and electronic switch without any mechanical switches.
• ☀☀☀The solar regulator is only suitable for lead acid batteries:lithium, OPEN, AGM, GEL. not for nickel hydride, Liions, or other batteries. For protecting the lifespan of your battery, once the voltage of the battery drop below 8V, the solar controller will turn off automatically
• ☀☀☀Easy to Use: Solar controller comes with a backlight display that can clearly indicate the status and data, it can be conveniently switched modes and parameter configuration.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.
• ☀☀☀Mutiple Electric Protection: short-circuit protection,open-circuit protection,reverse protection,over-load protection, more safty for using, suitable for home, industrial, commercial, etc small solar system,【Good Heat Dissipation】Dual mosfet Reverse current protection ,low heat production(avoid direct sunlight exposure or damp place)
