About this item

• 【 Three Battery Modes 】Independently charge and control each 12 volt battery with selectable charging modes among 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 Material】Made of premium Grade A+ solar cells, tempered solar glass and corrosion-resistant aluminum frame, withstand extreme weather conditions like UV, anti-rusting, and erosion, hail, and sandstorm.
• 【 Visual Charging Status】The digital charge controller allows to visually monitor charging status of PV charge current, battery voltage and state-of-charge among 25%-50%-75%-100%. It's not just a solar battery trickle charger, it's an advanced solar battery charger maintainer.
• 【 User-Friendly 】This solar panel battery charger ceases operation once the battery is fully charged and automatically restarts when the battery depletes, requiring no maintenance at all. Pre-drilled holes in the frame facilitate swift installation, and all cables are designed for simple plug-and-play connectivity, providing a hassle-free and efficient user experience.
• 【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.
• 【Ultra-Smart MPPT Technology】This 12v solar panel kit is crafted with SUNER POWER's innovative Ultra-Smart MPPT technology, 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.
• 【 Zero Discharge】This charge controller is powered by sunlight, unlike other brands' controllers that have parasitic drain on battery. It operates when there is effective sunlight and automatically turns off at sunset. A fully-automatic, worry-free smart 12 volt solar charger with zero discharge.
