The Gallagher S200 Solar Energizer is a self-contained solar-powered electric fence energizer designed for rotational grazing, livestock containment, and remote pasture fencing. With an integrated solar panel and rechargeable battery, the S200 provides reliable fence power where access to standard AC electricity is limited or unavailable.
Its portable, all-in-one design makes it an excellent option for producers who need dependable electric fencing without running power to remote areas of the farm.

Energizer Sizing Recommendation
We Recommend the 1 Joule Per Mile Rule
For real-world fence sizing, we recommend approximately 1 output joule for every mile of energized wire.
Be sure to calculate the total length of all energized strands, not simply the perimeter of the pasture.
For example, a ½-mile fence with three hot wires equals approximately 1½ miles of energized wire.
Vegetation, dry conditions, poor connections, and other fence loads may require additional energizer capacity.
Grounding Recommendation
We Recommend Approximately 3' of Grounding Per Output Joule
With approximately 1.5 output joules, we recommend roughly 4½–5 feet of total grounding as a starting point.
Soil conditions can significantly affect grounding performance. Dry, sandy, or rocky soils may require additional grounding.
Common Applications
Rotational grazing
Cattle fencing
Sheep and goat fencing
Remote pastures
Cross fencing
Pasture subdivision
Portable and semi-permanent fencing
Off-grid livestock fencing
Use Summary
The Gallagher S200 Solar Energizer provides a convenient middle ground between smaller portable solar units and larger high-output solar energizers. With its integrated solar panel, rechargeable battery, and approximately 1.5-joule output, it is a practical choice for rotational grazing and remote livestock fencing where dependable off-grid power is needed.
