Solar Charge Controller Reverse Connection Protection Low Power Consumption 5A MPPT Solar Panel Charge Controller Item Type: Solar Charge Controller Material: PCB Module Nature: with Real MPPT Solar Maximum Power Point Tracking Function, Automatic and Intelligent Charging Management, Low Power Consumption Input Voltage: Dc 8-28v Input Dc Voltage (prohibit Input of Ac Power) Output Voltage: Dc 5-26v Steplessly Adjustable Output Current: 2A 5A (There Are Two Types of Maximum Charging Current: a Version 5A, B Version 2A a Version with 5a is Shipped by Default) Charging Indicator: Fast Charging Red Light is On, Red and Blue Light Alternately Flashing when Fully Charged. Automatically Stop when Full. Mppt Function: Mppt Maximum Power Point Automatic Tracking Function, Can Make Full Use of Solar Energy Charging Minimum Voltage Difference: 1v (because It is a Stepping Down Voltage Regulator Module, the Input Voltage is at Least 1v Higher Than the Output) Ultra Low Power Consumption: Adopt Ultra Low Dropout Design to Achieve Low Power Consumption and Higher Conversion Efficiency, Professionally Adapted to Solar Panels Operating Temperature: Industrial Grade (-40℃ to +85℃) Load Regulation: ±1% Voltage Regulation Rate: ±0.5% Conversion Efficiency: Maximum: 93% Peaking: 95% Different Lighting Conditions Vary. Charging Method: Fully Automatic and Intelligent Three Stage Charging Mode. Self Tracking Solar Power Automatically Adjusts the Charging Current No Load Current: 3ma Can Easily Start Automatically Even in Weak Sunlight in the Morning, Eliminating the Need for Manual Switches. Input Reverse Connection Protection: Mos Tube Ultra Low Dropout Anti Reverse Connection Protection, Input Reverse Connection Does Not Work. Output Backflow Protection: Effectively Prevent the Battery's Electricity from Flowing Back to the Charging Board at Night Wiring Method: with Terminals Mppt Voltage: Arbitrarily Adjustable, Mppt Voltage of Different Solar Modules is Different, Low Power Consumption Design, Reduce Power Loss. the Mppt Function Can Effectively Prevent the Voltage of the Solar Panel from Being Dragged to Death by the Battery and Thus Charging Slowly Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Minnanxin
