?Ultra-Smart MPPT Technology?This 12v solar panel battery charger is crafted with SUNER POWER’s unique Ultra-Smart MPPT technology, the innovative MPPT ( Max Power Point Tracking) allows to deliver high tracking efficiency of up to 99% and peak conversion efficiency of 98%, improving approximately 20%-30% utilization rate than other competitors.
?Improved 3-stages Charging?The improved 3-Stages charging algorithm (Bulk, Absorption, Float) allows to charge 12-volt battery more effectively, ensures battery is safely recharged and increases battery life and performance.
?Free Maintenance?The solar trickle charger stops charging when battery has full charge, and automatically resumes when battery has discharge, totally free maintenance. A fully-automatic, worry-free and smart 12volt solar charger .
? Visual Charging Level?The charge level indicators allow to visually monitor the stage of charge among 25%-50%-75%-100%.
? Three Battery Charging Modes ?Independently charge and control each 12 volt battery with selectable charging modes – including 12V, 12V AGM and 12V Lithium – for all types of lead-acid boat, car, dump trailer, automotive, marine, RV, powersport, camper and deep cycle batteries, including flooded, gel, AGM, SLA, VRLA and maintenance-free, plus lifepo4 lithium batteries.
?Full Safety Protections?Built-in multiple protections including over-charge, over-discharge, over-voltage, over-current, over-load, short circuit, reverse polarity, and over-temperature, waterproof and spark-proof, the battery is fully protected.
?Superior Quality and Material?Made of premium Grade A+ solar cells with efficiency up to 21%-30%, tempered solar glass and durable corrosion-resistant frame, withstand extreme weather conditions like UV, anti-rusting, erosion, hail, and sandstorm.
?Easy to Use?Using the most advanced MPPT technology, this 12 volt solar battery charger starts charging immediately when it detects a battery. Pre-drilled holes allow for quick mounting with included suction cups, and all cables are plug and play, offering easy and quick using experience.
