Why customers choose Cera Garden

Effortless, reliable 12V charging for parked or active gear

Keep your 12V batteries ready when vehicles and equipment sit idle or when you’re out on the road. The Callsun 20W Solar Battery Charger & Maintainer combines high‑efficiency monocrystalline cells with an IP68 intelligent controller to deliver steady power without constant oversight. Designed for cars, boats, RVs, motorcycles, trailers, and more, this compact kit helps prevent battery drain and supports quick recharging under outdoor conditions.

Smart charging for 12V batteries

Smart, visible charging helps you stay in the know. An integrated chip auto-switches through the charging stages, and three status LEDs give a glance at the current phase. The system includes six protections to keep charging safe, even in challenging environments.

  • Three-stage charging (Bulk → Absorption → Maintenance) for efficient replenishment
  • Three status LEDs show the current charging stage at a glance
  • Six protections: anti-backflow, over-charge, over-voltage, over-current, short-circuit, and over-temperature

All-weather durability you can rely on

The panel is built to endure outdoor use with full potting and IP68 sealing to resist moisture. A low-iron tempered glass face and a corrosion‑ and rust‑resistant aluminum frame stand up to rain, dust, and temperature swings—from frigid mornings to hot afternoons.

  • IP68 weather sealing and full potting for moisture protection
  • Operates from 14°F to 158°F (-10°C to 70°C) with a rugged, weatherproof build
  • Long service life up to 25 years, reinforced by corner guards that absorb bumps

Complete kit, simple installation, and solid support

The package includes everything you need to get started quickly: solar panel, charge controller, 360° adjustable mount, alligator clip cable, O-rings, and mounting hardware. A 360° mount helps you optimize sun exposure, while 24/7 support and a 365‑day warranty provide peace of mind for everyday use.

  • All components included for a fast, tool-free setup
  • 360° adjustable mount maximizes daily solar intake
  • 24/7 support and a 365-day warranty
