Protect your livestock with confidence using the Australian-made Thunderbird S-21B 2km Solar Lithium Electric Fence Energiser, available from The Grit. Designed to power electric fencing up to 2 kilometres, this reliable unit delivers consistent performance in demanding rural environments.

The S-21B harnesses solar energy to efficiently charge its internal LiFePO₄ lithium battery, renowned for its long service life and enhanced safety. Producing up to 9,000 volts with 0.2 joules of stored energy, it provides dependable fence power day after day.

Built with the Australian landscape in mind, this energiser is fully self-contained and highly portable, featuring an integrated carry handle for easy relocation around your property. Installation is simple, with a design that slides neatly over a standard star picket.

Durability is a standout feature. The tough polycarbonate moulded casing is engineered to withstand harsh agricultural conditions, while internally coated electronics protect against moisture and environmental damage. An O-ring sealed enclosure and magnetic switch eliminate casing penetrations, significantly improving weather resistance. The unit is also angled to maximise solar panel exposure for optimal energy collection throughout the day.
