SUNER POWER 12V Solar Battery Charger and Maintainer

Revised Content:

【Smart MPPT Technology】This 12V solar panel battery charger is crafted with SUNER POWER's unique Smart MPPT technology. Its core components, including the MPPT charge controller and solar panel, are made using premium and durable materials. The innovative MPPT-Charge-Controller-Technology delivers a high tracking efficiency of up to 99% and a peak conversion efficiency of 98%, improving the utilization rate by approximately 20%-30% compared to other competitors.

【Improved 3-Stage Charging】The improved 3-Stage charging algorithm (Bulk, Absorption, Float) allows for more effective charging of 12-volt batteries. This ensures the battery is safely recharged and increases its life and performance. The charging will automatically cut off when the battery is fully charged and resume when it is not full, requiring no maintenance.

【Full Safety Protections】The charger is equipped with multiple built-in safety protections, including over-charge, over-discharge, over-voltage, over-current, over-load, short circuit, reverse polarity, and over-temperature. It is also waterproof and spark-proof, providing complete protection for the battery.

【Wide Compatibility】This is not just a solar battery trickle charger; it is an advanced solar battery charger maintainer. It is a fully-automatic, worry-free smart solar battery charger compatible with 12-volt sealed lead-acid car, automotive, marine, RV, powersport, boat, dump trailer, gate opener, fence, and deep-cycle batteries, including flooded, gel, AGM, SLA, maintenance-free, and LiFePO4 lithium batteries.

【Superior Quality and Material】The charger is made with premium Grade A+ solar cells with an efficiency of up to 21%-30%, tempered solar glass, and a durable, corrosion-resistant aluminum frame. It can withstand extreme weather conditions, such as UV, anti-rusting, erosion, hail, and sandstorms, and can handle up to 2400Pa wind pressure and 5400Pa snow load.

【Easy to Use】Utilizing the most advanced MPPT charge controller chip, this solar trickle battery charger maintainer starts charging immediately when the battery is connected. The pre-drilled holes on the solar panel frame allow for quick mounting with the included adjustable mount brackets, and all cables are plug-and-play, offering an easy and convenient user experience.
