20W 12V Solar Battery Charger with Controller, Pole Mount

Solar panel battery charger keeps 12V batteries topped up with reliable off-grid maintenance power for gates, fences, farms, and security setups. Using 20W monocrystalline cells and tempered glass, it delivers efficient trickle charging in outdoor conditions. A built-in smart controller helps protect your battery from common electrical faults, while the adjustable 0–60° pole-mount bracket makes it easy to angle toward the sun for better daily charging.

• Delivers 20W, 12V charging to help maintain batteries and reduce deep discharge during downtime


• Includes a built-in smart controller with protections for overvoltage, overcurrent, short circuit, overheating, and over/under-charge


• Fits 40–80 mm (1.5–3 in) poles with a 0–60° adjustable bracket for quick, secure mounting


• Supports multiple 12V battery types including LiFePO4, Li-ion, AGM, Gel, SLA, and EFB
