[Upgraded] 30A Solar Charge Controller, 12V/ 24V Solar Panel Regulator with Adjustable LCD Display Dual USB Port Timer Setting PWM Auto Parameter

【UPGRADED SOLAR CONTROLLER】This solar charge controller helps you manage the working of solar panels and batteries in solar systems automatically with the build-in industrial microcontroller. You don't need to reset it when the battery runs out cause it will memorize various parameters set by the user
【WIDE COMPATIBILITY BY AUTOMATIC ADAPTATION】Compatible with 12V and 24V systems (automatic adaptation, depends on your systems's voltage, no manual adjustments required). A little amplitude voltage deviation is normal. You can also charge your mobile phone, tablet, and PC through the Dual USB output 5V/2.5A (max)
【COMPATIBLE BATTERY TYPE】This solar controller is ONLY suitable for various Lead-acid batteries (including open, sealed, colloid, etc.) Please DO NOT charge to lithium or nickel-metal hydride batteries, etc. Auto-recognizing battery voltage function can protect the battery from misuse and better control the charging process. Note: When installing the controller for the first time, please ensure the battery is fully charged to recognize the battery type correctly
【SAFE TO USE】With Intelligent protection against overcurrent, short-circuit, open-circuit, inverse, low voltage, and overcharge, all of which are automatic recovery types, do not damage the controller. It also has a dual MOS anti-backflow circuit and low heat. This 30A solar charge controller will help you improve the system efficiency and prolong the battery life. But still note to install the controller on a flat, well-ventilated surface
【LCD DISPLAY】Let you know the working status and data with the LCD. The regulator equips load time control and a manual setting function, so you can switch modes and configure parameters conveniently. A good choice for use at home, industrial, commercial, etc. See the instruction manual for specific parameter settings and adjustment methods
