Built for Distance. Powered by Daylight. Gallagher launches the S120 Lithium Solar Energizer
Thursday, 15 January, 2026
Gallagher Animal Management, inventor of the livestock electric fence and world leader in agritech innovation, proudly announces the launch of its most powerful lithium-powered solar energizer to date — the S120 Lithium Solar Fence Energizer. Purpose-built for farmers, ranchers, and land stewards who demand performance without compromise, the S120 delivers 1.2 Joules of adaptive power through Gallagher’s market-leading integrated solar technology.
Power to fence anywhere
Engineered for remote pastures, tough terrain, and heavy stock pressure, the S120 Lithium provides reliable, self-sufficient power where the grid can’t reach, powering up to 12 km of fencing. Designed for rotational grazing, ecological stewardship, and off-grid small scale wildlife defence, the S120 builds on the success of Gallagher’s proven lithium range with faster charging, longer battery life, and intelligent adaptive energy control.
“The S120 Lithium is the heavy hitter of our leading lithium range,” said Byron Arnold, Product Manager. “It’s built for serious off-grid performance, rugged, portable, and smart, enabling farmers and ranchers to confidently manage livestock and wildlife wherever they operate. It just keeps on ticking.”
The Benchmark for Integrated Solar Innovation
Gallagher pioneered the integrated solar energizer category by bringing Lithium technology to the industry. The new S120 Lithium continues that legacy, upgrading from the popular S100 with enhanced lithium battery technology, lighter weight, and greater power output — demonstrating Gallagher’s position as the global leader in integrated solar performance.
With its fast-charging lithium battery and intelligent adaptive energy control, the S120 Lithium automatically adjusts to changing sunlight and battery levels, ensuring consistent performance in all conditions and keeping fences live when and where it matters most.
Smarter Power. Reliable Defence.
Versatile by design, the S120 Lithium offers two operating modes to suit every environment: a Livestock Mode that conserves energy by pulsing faster during the day and slower at night when livestock are less active, and a Wildlife Mode that maintains a fast 24/7 pulse to deter pests and protect boundaries and livestock.
Rugged yet lightweight, it features IPX4 weather protection, lightning defence, and a dual-insulated enclosure that shields internal circuitry from extreme temperatures. Its high-efficiency 12-Watt solar panel provides long-lasting, self-sufficient power day and night. Backed by Gallagher’s trusted three-year warranty (battery included), the S120 Lithium delivers total peace of mind, season after season.
Empowering the Future of Grazing and Land Stewardship
From rotational grazing systems and ecological regeneration to wildlife protection, the S120 Lithium empowers users to manage their land efficiently, sustainably, and securely. Designed for farmers, ranchers, and environmentalists, the S120 Lithium enables flexible fencing solutions for livestock control, pasture management, and conservation.
