When you need dependable electric fencing in places where power isn’t always close by, the Gallagher S120 Lithium is built to keep things moving. Gallagher’s most powerful lithium-powered solar energizer, the S120 delivers 1.2 Joules of stored energy and up to 10kV output, providing reliable off-grid performance for livestock management, rotational grazing and remote fencing.
Lightweight, rugged and easy to move, the S120 is made for life on the farm or station. It can power up to 16 km of multiwire fencing under Gallagher’s recommended conditions, or up to 56 km (35 miles) in ideal conditions, giving you plenty of flexibility when managing larger areas.
Its clever adaptive energy control constantly monitors available solar energy and battery levels, automatically adjusting the energizer’s output to make the stored power last as long as possible. So even when the sun isn’t shining, your fence can keep working.
The S120 combines a lithium iron phosphate battery with a highly efficient 12-watt solar panel, providing self-sufficient power day and night. The internal lithium battery is designed for long-lasting performance, while the solar panel keeps it topped up during daylight hours.
Two operating modes allow you to tailor the energizer to your fencing needs:
Livestock Control Mode — Faster pulses during the day and slower pulses at night to suit domestic livestock activity.
Wildlife Control Mode — Fast pulses day and night, with reduced power output to help conserve battery life.
The S120 features a dual-insulated enclosure to protect the battery and internal circuitry from temperature extremes. Its IPX4 water-resistant case and built-in lightning protection help keep your energizer working when the weather turns rough.
LED indicators make it easy to check battery levels and identify faults at a glance, while the unique post-mounting system keeps the energizer safely off the ground and away from livestock and rising water. It also helps keep grass from shading the solar panel.
With its compact design and integrated carry handle, the S120 is easy to install, shift and reposition around the farm. It’s particularly handy for rotational grazing and managed pasture systems, where your fencing setup can change from one paddock to the next.
Simply mount it to a suitable post, connect the fence and earth leads, and you’re ready to go.
