Ultra-Smart MPPT Technology

Designed with SUNER POWER’s proprietary Ultra-Smart MPPT technology, this 12V solar panel battery charger boasts innovative MPPT (Maximum Power Point Tracking) capabilities. This technology ensures a tracking efficiency of up to 99% and peak conversion efficiency of 98%, marking an approximate 20%-30% improvement over competitors.

Improved 3-Stage Charging

Equipped with an enhanced 3-stage charging algorithm (Bulk, Absorption, Float), this charger optimizes battery charging efficiency. It ensures safe and effective recharging, extending battery lifespan. Once the battery is fully charged, the solar trickle charger stops automatically, and resumes charging when needed, eliminating the need for manual maintenance.

Full Safety Protections

This solar panel battery charger is built with multiple safety features, including over-charge, over-discharge, over-voltage, over-current, over-load, short circuit, reverse polarity, and over-temperature protection. It is also waterproof and designed to be spark-proof, providing complete protection for your battery.

Three Battery Charging Modes

Supporting independent charging and control for various 12V batteries, this product offers three charging modes: 12V, 12V AGM, and 12V Lithium. It is compatible with all types of lead-acid batteries, including flooded, gel, AGM, SLA, VRLA, and maintenance-free batteries, as well as lithium-based lifepo4 batteries.

Visual Charging Level

With charge level indicators showing stages from 25% to 100%, you can easily monitor the charging status. This advanced charger not only acts as a solar battery trickle charger but also serves as a comprehensive solar battery charger maintainer. It is fully automatic and ensures no overcharging, providing a worry-free experience.

Superior Quality and Material

Crafted with premium Grade A+ solar cells offering up to 21%-30% efficiency, this charger is built with tempered solar glass and a durable, corrosion-resistant aluminum frame. It is designed to withstand extreme weather conditions such as UV exposure, anti-rust, erosion, hail, and sandstorms. It can handle up to 2400Pa wind pressure and 5400Pa snow load.

Easy to Use

Using the most advanced MPPT charge controller chip, this solar battery charger starts charging immediately upon battery registration. Pre-dilled holes on the frame facilitate quick mounting, and all cables are plug-and-play, making setup incredibly easy and convenient.
