Built for distance. Powered by daylight.
The S120 Lithium is Gallagher’s most powerful Lithium powered solar energizer, delivering 1.2 Joules of adaptive energy through market-leading solar technology. Whether you're managing livestock, nurturing pastures, or protecting remote boundaries, the S120 Lithium empowers you with reliable, off-grid performance built for nature’s rhythm.
Lightweight, rugged, and ready to move, the S120 is designed for rotational managed grazing, ecological stewardship, and serious off-grid wildlife defense. It powers up to 35 miles of fencing, with intelligent energy control that adapts to sunlight and battery levels, ensuring your fence stays hot - even in tough conditions.

Features
-
Solar Lithium Technology
Lithium iron phosphate battery and high efficiency solar panel provide superior and continuous product operation, with a maximum output voltage of 10kV.
-
Faster charging, long-lasting battery performance
An internal heavy-duty lithium battery and a highly efficient 12-Watt solar panel provide superior, long-lasting, self-sufficient power on your fence line, day and night.
-
Intelligent adaptive energy control
Smart adaptive electronics are constantly monitoring the solar energy being stored, measuring it against the battery voltage and adjusting the output energy to ensure your fence is powered for as long as possible – even in the absence of sunlight.
Energizer pulse intervals and voltage output reduces as the battery state of charge drops below 30%
-
Multiple power options to suit your fencing application
Two operating modes ensure optimum battery management and animal control specific to your fencing requirements.
Livestock control mode: Operates with a fast pulse during the day, and slower pulse at night for when domestic animals are less active.
Wildlife control mode: Operates with a fast pulse day and night with reduced power output to conserve battery voltage.
-
Protected circuitry and battery longevity
Dual insulated plastic enclosure protects internal circuitry and lithium batteries from extreme temperatures.
-
Confidence in every fence pulse
Peace of mind, built in. Lithium Solar Fence Energizers are backed by a 3-year warranty, including the battery—reliability is not in question.
-
Heavy duty performance with lightweight portability - designed to be easily moved around the farm or ranch
Lightweight, compact and easy to install and move with an integrated carry handle. Making it the ideal solution for managed grazing and rotational pasture management.
-
Fence and Energizer performance indication at a glance
LED lights indicate if the built-in lithium battery is running low or if there is a fault.
-
Designed for the outdoors. Rain, hail or shine
Water resistant case with IPX4 rating, and built-in lightning protection keeps power maintained in all weather conditions.
-
Post mounted for security and reliability
Unique post mounting system keeps the energizer off the ground, protecting it from stock and rising water, while also preventing grass from shielding the solar panel. Mount to a Y/T Steel Post, a wood post*, or a metal rod/pipe* up to 22mm/1” in diameter.
*Wood Post/Earth(Ground) Mount included with energizer (G57112)
-
Fully integrated, ready to use
Simply mount on a suitable post and connect it to your fence and earth stake/ground rod. Includes fence and ground lead, rechargeable lithium battery and 12-Watt solar panel.
