Product description

As we all know, batteries naturally drain power and if allowed to go flat, may never regain their full power. This product is a solar powered battery maintainer and charger for 12V batteries and helps manage battery drain in all season. The solar charger converts light energy from the sun into 12 volt DC electricity which is then transported to the rechargeable batteries through lead wire and connector of choice, replace the self-discharge of a battery in storage, so that the battery wouldn’t “go dead”. It can be used for gate opener, electrical fencer, cars, 4WD’s, trucks, motorcycle, marine, boats, farm equipment or any application where a 12v battery is used.

The high efficient solar panel allows to absorb a wider spectrum of sunlight, as long as there is sufficient sunlight available, the charger will generate an electrical current to trickle charge the battery. The charger is built in the most super-intelligent MPPT(Maximum Power Power Tracking) chip to intelligently charge and fully protect the battery. The MPPT technology helps to generate at least 20%-30% more power than traditional PWM. And the LED indicator helps better understand the charging status on all days.

Adjustable Anagle

The adjustable joint ball make it possible to adjust the angle of solar panel to get as much as sunshine, increase 2%-3%more power.

High Efficiency Solar Cell

Made of high effciciency, 30% more than competitor, works great in sunlight.

IP 65 Waterproof

IP 65 waterproof design, withstand rain and snow, no worry to mount it outside, totally free maintenance.

【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. The solar trickle charger stops charging when battery has full charge, and automatically resumes when battery has discharge, totally free maintenance.
【 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.
【 Superior Quality and Material】Made of premium Grade A+ solar cells with efficiency up to 21%-30%, tempered solar glass and durable corrosion-resistant aluminum frame, withstand extreme weather conditions like UV, anti-rusting, and erosion, hail, and sandstorm, up to 2400Pa wind pressure and 5400Pa snow load.
【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 mounting brackets, and all cables are plug and play, offering easy and quick using experience.
