? UltraSmart MPPT Technology ?This 12v solar panel battery charger is crafted with SUNER POWER’s unique UltraSmart MPPT technology, so all of its core parts, including its mppt charge controller and solar panel are built using premium and durable materials. The innovative MPPT-Charge-Controller-Technology allows to deliver high tracking efficiency of up to 99% and peak conversion efficiency of 98%, improve 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. The charging will be cut off when battery is fully charged, and automatically resumed when battery is not full, totally free maintenace.
? 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.
? 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.
? Visual Charging Level?The charge level indicators allow to visually monitor the stage of charge among 25%-50%-75%-100%. It’s not just a solar battery trickle charger, it’s an advanced solar battery charger maintainer. A fully-automatic, worry-free smart solar battery charger with zero overcharge.
