Free Maintenance

Automatically stops when the battery is full and resumes when discharge occurs, delivering a fully automatic, low-maintenance charging solution.

Safety Protections

Designed with multiple safeguards to protect both the panel and the battery in real-world conditions.

  • Over-charge protection

Three Battery Charging Modes

Independently manage charging for each 12V battery with modes optimized for different chemistries, including 12V lead-acid variants, AGM, and lifepo4 lithium batteries.

Adjustable Pole Mount Brackets

The included brackets let you fine-tune the panel angle from flat to several tilt positions, helping you optimize sun exposure on poles with diameters from 1.5 to 3.0 inches.

Durability and Weather Resistance

Crafted with Grade A+ solar cells, tempered glass, and a corrosion-resistant frame, the unit is built to handle outdoor conditions like UV exposure, rust, and wind-blown debris.

Real-Life Scenarios
