Gallagher S20 Solar Electric Fence Charger 0.2 Joule Solar Powered Energizer Powers Up to 12 Miles, 40 ac of Fence

Power rotational grazing, poultry, garden, and small livestock fencing without carrying a separate battery or relying on a nearby outlet. The Gallagher S20 lithium solar electric fence energizer stores 0.2 joules and delivers 0.15 joules of output. It is rated for approximately 2 miles of typical multi-wire fence and up to 12 miles of clean fence under suitable conditions. An internal lithium iron phosphate battery and 3-watt high-efficiency solar panel provide self-contained power through daily light changes with a maximum output voltage of 9.3 kV. Intelligent adaptive energy control compares incoming solar energy with battery voltage and adjusts pulse output to extend operation during limited sunlight. LED indicators identify low fence voltage and a low battery, helping the user respond before containment is affected. An integrated carry handle and compact body make the energizer easy to relocate between temporary fence sections. Fence and ground leads, the rechargeable battery, and the solar panel are included. A water-resistant enclosure, protected internal circuitry, and built-in lightning protection support outdoor operation through changing weather. Actual capacity depends on sunlight, battery condition, grounding, wire count, conductor resistance, vegetation, soil moisture, and fence maintenance. Position the panel for direct sun, keep plants clear of the live wires, and test voltage at the far end of the fence after setup. The S20 is backed by a three-year manufacturer warranty.
