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

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, 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, replacing the self-discharge of a battery in storage, so that the battery wouldn't "go dead." It can be used for cars, 4WD's, trucks, motorcycles, marine, boats, farm equipment, or any application where a 12V battery is used.

The high-efficient 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 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. The LED indicator helps better understand the charging status at all times.

Visual LED Indicator: - Blinking Green: Sunshine is effective (Not Active yet) - Blinking Red: Working to charge battery (Activated) - Solid Green: Battery is fully charged - Solid Red: Error-Reversed polarity

High Efficiency Solar Cells: Made of high-efficiency solar cells, 30% more than competitors, and works great in sunlight. The surface is covered by tempered solar glass, protecting the solar cells from snow, hail, dust, etc.

IP65 Waterproof: The IP 65 waterproof design allows it to withstand rain and snow, with no need to worry about mounting it outside. It is totally maintenance-free.

About SUNER POWER: SUNER POWER was founded by a team of technicians who worked together for at least 10 years in the solar industry prior to starting the company. Our mission is to serve our customers by bringing transparency, simplicity, products, and services through the competitive marketplace. We are committed to providing home and business owners with an easy way to be powered by affordable, clean, and reliable solar power.

UltraSmart MPPT Technology: This 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 allows for the delivery of 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-Stages Charging: The improved 3-Stages charging algorithm (Bulk, Absorption, Float) allows for the more effective charging of 12-volt batteries, ensuring the battery is 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, totally maintenance-free.

Full Safety Protections: The charger is built with multiple protections, including over-charge, over-discharge, over-voltage, over-current, over-load, short circuit, reverse polarity, and over-temperature, as well as being waterproof and spark-proof, ensuring the battery is fully protected.

Wide Compatibility: This is not just a solar battery trickle charger, but an advanced solar battery charger maintainer. It is a fully-automatic, worry-free smart solar battery charger for 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.

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

Easy to Use: Using the most advanced MPPT charge controller chip, this solar trickle battery charger maintainer starts to charge immediately when the battery is registered. 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 using experience.
