[Compact and Portable] Improved charge controller, MPPT (Maximum Power Point Tracking) charge controller provides maximum utilization of solar energy to charge the system, it is 25% smaller in size, but can capture up to 15%-30% performance, can charge the battery without additional self-consumption. High tracking efficiency up to 95%, compared to 65%-80% for charge controllers. Automatic detection of 12V DC system voltage.[Comprehensive Protection for Safety] Built-in internal protection system and intelligent 3-stage charging to protect your battery from overcharge, over-discharge, over-voltage, overload, short circuit, reverse polarity and over-temperature, and the battery is highly efficient, safely charged to 100%.[Compatible with Multiple Batteries] Compatible with 12 volt batteries, Gel, Deep Cycle, Sealed, Lead-acid, Flooded and LiFePO4 lithium batteries. 3-stage smart charging: Boost, Float and Equalize to get the most out of your solar energy. Perfect for deep cycle, marine, vehicle and more.[Visual Monitoring & No Power Consumption] Equipped with a digital LCD display, visually monitor the working conditions of solar panels and batteries. Powered directly by sunlight, cannot drain the battery! Please expose the solar panel to sunlight, make sure there is no shade or cloudy to get enough sunlight to activate the charge controller.[Temperature Compensation] Integrated thermal temperature sensor eliminates overcharging in hot climates and undercharging in cold climates.[Easy to Use] SAE connector can be quickly connected or disconnected, plug and play. Very functional and functional. IMPORTANT: This MPPT charge controller has standard polarity as shown in the user manual image, if the solar panel does not match the charge controller, a polarity adapter is required. Check out our MPPT, with polarized adapter.Color: BlackMaterial: plasticPackage contents:1 x Solar Panel MPPT ControllerOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
