SOLAR ENERGISER S120 12KM GALLAGHER G35210
The S120 Lithium is Gallagher's most powerful lithium-powered solar energizer, delivering 1.2 joules of adaptive energy through market-leading solar technology.
Gallagher's Solar Energizers are fully self-sufficient and use solar power to charge your electric fence. These units can be used in permanent electric fencing where there is no access to mains power, and also for portable, short-term animal control. Powering up to 12 km of fence, the S120 is built for reliable, off-grid performance — whether you're managing livestock, nurturing pastures, or protecting remote boundaries.
Overview:
Solar lithium technology:
A lithium iron phosphate battery paired with a high-efficiency 12-watt solar panel provides superior, continuous operation, with a maximum output voltage of 10 kV — self-sufficient power on your fence line, day and night.
Intelligent adaptive energy control:
Smart electronics constantly monitor the solar energy being stored against the battery voltage, adjusting output to keep your fence powered for as long as possible — even in the absence of sunlight.
Multiple power options:
Two operating modes to suit your fencing application — Livestock control mode (fast pulse by day, slower by night) and Wildlife control mode (fast pulse day and night at reduced power to conserve the battery).
Battery status indicator:
LED lights indicate at a glance if the built-in lithium battery is running low or if there's a fault.

Common Questions
How much fence will the S120 power?
Up to about 12 km, on roughly 3 ha — it's the highest-output solar energiser in Gallagher's S-series at 0.6 stored joules.
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.
