SUNER POWER Waterproof 12W 12V Solar Battery Charger & Maintainer Pro for Car, Automotive, Boat, Marine, RV, Trailer

As we all know, batteries naturally drain power, and if allowed to go flat, may never regain their full capacity. This product is a solar-powered battery maintainer and charger for 12V batteries, helping to manage battery drain in all seasons.

The solar charger converts light energy from the sun into 12-volt DC electricity, which is then transported to the rechargeable batteries through a lead wire and connector of choice. This helps replace the self-discharge of a battery in storage, so the battery doesn't "go dead." It can be used for cars, 4WDs, trucks, motorcycles, marine applications, boats, farm equipment, or any application where a 12V battery is used.

The high-efficiency solar panel allows for the absorption of 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 with the most advanced MPPT (Maximum Power Point Tracking) chip, which intelligently charges and fully protects the battery. The MPPT technology helps generate at least 20%-30% more power than traditional PWM. The LED indicator helps better understand the charging status on any given day.

The LED indicator allows for clear monitoring of the working status: Blinking green indicates that sunshine is effective (not yet activated), blinking red indicates the charger is working to charge the battery (activated), solid green indicates the battery is fully charged, and solid red indicates an error, such as reversed polarity.

The solar cells are made of high-efficiency materials, 30% more efficient than competitors, and perform great in sunlight. The surface is covered by tempered solar glass, protecting the solar cells from snow, hail, dust, and other environmental factors. The IP65 waterproof design allows the charger to withstand rain and snow, enabling it to be mounted outdoors without worry, and requiring minimal maintenance.

SUNER POWER was founded by a team of technicians who had worked together for at least 10 years in the solar industry prior to starting the company. The company is committed to serving customers by bringing transparency, simplicity, and affordable, clean, and reliable solar power solutions to home and business owners.

This 12V solar panel battery charger is crafted with SUNER POWER's unique UltraSmart MPPT technology, ensuring all core parts, including the MPPT charge controller and solar panel, are built using premium and durable materials. The innovative MPPT-Charge-Controller-Technology allows for 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.

The improved 3-stage charging algorithm (Bulk, Absorption, Float) allows for more effective charging of 12-volt batteries, ensuring they are safely recharged and increasing battery life and performance. The charging will be cut off when the battery is fully charged and automatically resumed when the battery is not full, requiring no maintenance.

The charger is built with multiple safety protections, including over-charge, over-discharge, over-voltage, over-current, over-load, short circuit, reverse polarity, and over-temperature, making it waterproof and spark-proof, fully protecting the battery.

This solar battery charger is compatible with a wide range of 12-volt sealed lead-acid car, automotive, marine, RV, powersport, boat, dump trailer, motorcycle, trolling motor, tractor, ATV, and deep-cycle batteries, including flooded, gel, AGM, SLA, and maintenance-free, plus LiFePO4 lithium batteries.

The charger is made of premium-grade A+ solar cells with efficiency up to 21%-30%, tempered solar glass, and a durable, corrosion-resistant frame, allowing it to withstand extreme weather conditions such as UV, anti-rusting, erosion, hail, and sandstorms, up to 2400Pa wind pressure and 5400Pa snow load.

Using the most advanced MPPT charge controller chip, this solar trickle battery charger maintainer starts charging immediately when the battery is connected. Pre-designed holes on the solar panel frame allow for quick mounting with the included suction cups, and all cables are plug-and-play, offering an easy and quick user experience.
