Keep Your 12 V Batteries Charged With the Sun
A car that sits in the garage all winter, a boat on its trailer, an RV, a tractor or a ride-on mower: batteries that stand still go flat. This 20 W solar charging kit turns sunlight into steady charging power that keeps compatible 12 V batteries topped up, with no mains socket needed.
Charge with solar
Reliable power, zero outlets
The high-efficiency monocrystalline solar panel delivers steady charging, while the waterproof smart charge controller regulates the current and protects your battery.
Together with the adjustable mounting bracket and the complete connection kit, it is one dependable battery maintenance system that runs on clean, renewable solar energy wherever you are.
Smart charge controller
Protects your battery while it charges
The waterproof controller automatically regulates charging and has indicator lights that show the charging status at a glance.
- Overcharge protection
- Reverse polarity protection
- Reverse current protection
- Short circuit protection
Built for outdoor conditions
Leave it outside all year
The aluminium alloy frame and waterproof controller are designed for long-term outdoor use in normal weather. The panel is rated for temperatures from about -40 °C to 85 °C (-40 °F to 185 °F).
Inside the panel
Six layers, built to last
Low-iron tempered glass on top, EVA film on both sides of the monocrystalline solar cells, a rust-proof aluminium frame and a TPT backsheet underneath.
Why a framed glass panel
Tougher than plastic or flexible panels
A sturdy aluminium frame and tempered glass hold up much better outdoors than a plastic-shell panel, which ages easily, or a flexible panel whose solar cells are fragile.
