Features: 1. Upgraded version of solar panel controller: Compatible with 12V 24V system. This solar charge controller helps you automatically manage the work of the solar panels and batteries in your solar system using a built-in industrial microcontroller. No need to reset when the battery runs out, because it remembers various parameters set by the user. You can also charge your phone, tablet, PC with dual USB outputs up to 5V/2.5A.2. Safe to use: Equipped with overcurrent protection, short circuit protection, reverse connection protection, low voltage, overcharge protection, with full 3-stage PWM charging management. This solar charge controller will help you safely increase system efficiency and extend battery life.3. LCD Display: The LCD display keeps you informed of status and data. You can also switch modes and parameter configurations, and you can use the controller in different such as home, industry, and business.4. Multiple electrical protections: Built-in over current protection, short circuit protection, reverse polarity protection, open circuit protection, automatic recovery, and no damage to the controller, providing reliable protection for your equipment.5. Good heat dissipation: Double MOSFET reverse current protection, low heat generation, all electronic components will heat up during the working process, it is best to shade them for better heat dissipation, and avoid direct sunlight or humid .Rated charging current:100ABattery Voltage:12V 24V AutoCharge reconnect:13VUSB output:5V/3AStandby current Less than10mAWorking temperature -35C~+60CWarmly Tips: The reverse order applies when deinstalling!An improper sequence order can damage the controller!All red color voltage X2 , while using 24V system.This solar controller is not waterproof , please install it indoor or out of the rainsize: about 130 x 72 x 25mmMaterial: ABScolour: Black+BluePackage Contents: 1 x Solar Controller
