This setup blends unobtrusively with your gear while helping keep batteries ready when needed.

Smart, safe, and versatile maintenance

  • Six layers of protection help guard the battery during charging: reverse charging, overcharge, overvoltage, overcurrent, short circuit, and over temperature safeguards.
  • Wide 12V compatibility supports maintenance for LiFePO4, AGM, SLA, GEL, FLA, EFB, MF and certain Li-ion cells where supported, making it suitable for a range of vehicles and setups.
  • Durable, outdoor-ready construction uses IP68 waterproof materials with a corrosion-resistant aluminum frame to withstand wind, rain, and snow.

Efficient, real-time solar management

  • The smart controller tracks panel power in real time to maximize charging effectiveness, offering potential efficiency gains over traditional controllers.
  • A 360° adjustable mount enables flexible installation on walls, roofs, or boats, and corner protectors help prevent damage from minor impacts.
