UltraSmart MPPT Technology

Crafted with SUNER POWER's unique UltraSmart MPPT technology, this 12V solar panel battery charger is built using premium and durable materials. The innovative MPPT-Charge-Controller-Technology offers up to 99% high tracking efficiency and a peak conversion efficiency of 98%, with approximately 20%-30% improved utilization rate compared to other competitors.

Improved 3-Stage Charging

The enhanced 3-stage charging algorithm (Bulk, Absorption, Float) optimizes battery charging, ensuring safe recharging and extended battery life and performance. Charging automatically stops when the battery is fully charged, resuming only when necessary, completely maintenance-free.

Full Safety Protections

Equipped with multiple built-in protections, including over-charge, over-discharge, over-voltage, over-current, over-load, short circuit, reverse polarity, and over-temperature, this charger ensures top-tier safety. Additionally, it is waterproof and spark-proof, fully protecting the battery.

Adjustable Pole Mount Bracket

Easily adjustable pole mount brackets allow you to set the solar panel angle between -15°, 0°, 30°, and 45°, suitable for pole diameters of 1.5-3.0 inch/40-80MM.

Three Battery Charging Modes

Select between 12V, 12V AGM, and 12V Lithium modes to independently charge and control all types of lead-acid, car, RV, marine, powersport, and deep cycle batteries, including flooded, gel, AGM, SLA, VRLA, maintenance-free, and LiFePo4 lithium batteries.

Visual Charging Level

Monitor the charging stage with visual indicators for 25%, 50%, 75%, and 100%. This advanced solar battery charger is not just a trickle charger; it is a smart maintainer, ensuring zero overcharge.

Superior Quality and Material

This solar panel battery charger is made of Grade A+ solar cells with up to 21%-30% efficiency, tempered solar glass, and a durable corrosion-resistant aluminum frame. It withstands extreme weather conditions, including UV resistance, anti-rusting, erosion, hail, and sandstorms, with wind pressure resistance up to 2400Pa and snow load up to 5400Pa.

Easy to Use

Powered by the most advanced MPPT charge controller chip, this charger starts charging immediately when the battery is registered. Pre-dilled holes on the frame enable quick mounting with adjustable pole mount brackets, and all cables are plug-and-play, offering easy and quick usage.

With these features, this solar panel battery charger is the perfect solution for reliable and efficient battery management, ensuring your batteries are always in top condition.
