Compact 10W Solar Charger & Maintainer for Car, Boat, RV

This product is a solar-powered battery maintainer and charger for 12V batteries, helping 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 the lead wire and connector of choice. This replaces the self-discharge of a battery in storage, ensuring the battery does not "go dead." It can be used for cars, 4WD's, trucks, motorcycles, marine applications, boats, farm equipment, or any application where a 12V battery is used.

Made with high-efficiency solar cells, this charger can 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 with the most intelligent MPPT (Maximum Power Point Tracking) chip to intelligently charge and fully protect the battery. The MPPT technology helps generate at least 20%-30% more power than traditional PWM. The LED indicator allows the user to better understand the charging status at all times.

The visual LED indicator provides clear monitoring of the working status: blinking green indicates sunshine is effective (not yet active), 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 high-efficiency solar cells are made with 30% more efficiency than competitors, performing great in sunlight. The surface is covered by tempered solar glass, protecting the solar cells from snow, hail, dust, and other elements. The IP65 waterproof design allows the charger to withstand rain and snow, making it worry-free to mount it outside with no maintenance required.

SUNER POWER was founded by a team of technicians with at least 10 years of experience in the solar industry. The company is committed to providing home and business owners with an easy way to be powered by affordable, clean, and reliable solar power.

The 12V solar panel battery charger is crafted with SUNER POWER's unique UltraSmart MPPT technology, ensuring its core parts, including the MPPT charge controller and solar panel, are built using premium and durable materials. The innovative MPPT-Charge-Controller-Technology delivers 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 the charger to effectively charge 12-volt batteries, ensuring the battery is safely recharged and increasing its 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 maintainer 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, maintenance-free, and LiFePO4 lithium batteries.

The charger is made with 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 like UV, anti-rusting, erosion, hail, and sandstorms, with a wind pressure rating of up to 2400Pa and a snow load rating of 5400Pa.

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.
