SUNER POWER 12V 50W Solar Battery Trickle Charger & Maintainer | Waterproof MPPT Controller + Adjustable Pole Mount

Overview

Meet the SUNER POWER 12V 50W Solar Battery Trickle Charger & Maintainer. This compact outdoor solution keeps your 12‑volt batteries ready for action, blending weatherproof design with an integrated Ultra-Smart MPPT controller. It’s built to be low-maintenance while delivering reliable, on-site charging for a variety of battery types.

Ultra-Smart MPPT Power and Efficiency

The built‑in MPPT technology tracks the maximum power point with impressive efficiency. Expect up to 99% tracking and around 98% peak conversion, which can translate to better energy use in fluctuating light conditions and more consistent performance across seasons.

• High tracking efficiency helps harvest more energy from variable sun
• Peak conversion supports effective use of available solar power

Three-Stage Charging and Broad Battery Support

The charger employs a refined three-stage charging algorithm (Bulk, Absorption, Float) to recharge 12‑volt batteries safely and efficiently, potentially preserving battery health over time. It is compatible with a wide range of lead‑acid types and LiFePO4 formats.

• Bulk: rapid initial charge
• Absorption: controlled voltage taper
• Float: maintenance-ready once full

Maintenance-Free Operation and Robust Protections

Once the battery reaches full charge, charging stops automatically and resumes when needed. The unit includes multiple protections (over-charge, over-discharge, over-voltage, over-current, short circuit, reverse polarity, and temperature) and is designed to be waterproof and spark-proof for outdoor use.

• Automatic resume after discharge keeps batteries topped up
• Comprehensive safety protections reduce risk during use

Visual Charge Status and Durable Build

Charge level indicators provide a quick visual readout at 25%, 50%, 75%, and 100%, so you can monitor progress at a glance. Built with Grade A+ solar cells, tempered glass, and a corrosion‑resistant frame, it’s designed to withstand harsh outdoor conditions.

• Clear, at-a-glance charge levels
• Durable construction for UV, rust, hail, and sand exposure

Mounting Flexibility and Battery Versatility

Adjustable pole mount brackets let you angle the panel for optimal sun exposure. The brackets fit select pole sizes and allow angle settings from flat to up to approximately 60 degrees, making placement easier in varied outdoor spaces. Compatible with 12V lead-acid, AGM, flooded, VRLA, and LiFePO4 batteries, including lifepo4 variants.

• Flexible angle adjustments for better sun capture
• Supports multiple battery types and chemistries
