Gallagher S120 Lithium Solar Fence Energizer
The Gallagher S120 Lithium Solar Fence Energizer is a powerful, fully integrated solar energizer designed for larger portable and off-grid electric fencing systems. It is particularly well suited to rotational grazing, remote paddocks and situations where reliable mains power is unavailable.
Powered by a heavy-duty lithium iron phosphate battery and 12-watt solar panel, the S120 uses intelligent adaptive electronics to monitor available solar energy and battery charge, adjusting its operation to maintain reliable fence performance through changing weather conditions.
The S120 delivers 1.2 joules stored energy and 0.94 joules output, with Gallagher recommending it for approximately 4 km of multiwire fencing, and up to 12 km under ideal conditions. Livestock and wildlife operating modes allow the energizer to adjust its pulse behaviour to suit different applications.
Its compact post-mounted design keeps the energizer clear of stock, grass and rising water, while LED indicators provide quick information about battery condition and fence performance.
Key features include:
- 1.2 J stored energy / 0.94 J output
- Recommended for approximately 4 km of multiwire fence
- Up to 12 km under ideal conditions
- Integrated 12 W solar panel
- Lithium iron phosphate battery
- Intelligent adaptive energy management
- Livestock and wildlife operating modes
- Integrated carry handle for portability
- LED status indicators
- Built-in lightning protection
- IPX4 weather-resistant construction
- 3-year warranty including battery
A strong solar option for producers wanting more capacity than a small portable energizer without requiring mains power.
Common Questions
How much fence will the S120 power?
In ideal conditions — a clean, single-wire fence — up to about 12 km. Treat that figure as a comparison guide rather than a promise on every fence: a multi-wire fence or one running through grass and scrub is a much bigger electrical load and will cover less distance (Gallagher's recommended multi-wire guide for this unit is around 4 km). The S120 is the highest-output solar energiser in Gallagher's S-series, delivering 1.2 stored joules (about 0.94 joules output). Size to your actual fence load and live wires, then confirm performance with a fence tester once it's installed.
Is it good in poor weather?
Yes. Adaptive energy control and a lithium iron phosphate battery give strong cold-weather and low-light performance, with built-in lightning protection.
Is the battery covered by warranty?
Yes — the 3-year warranty includes the battery.
