Gallagher S20 Solar Fence Energizer | 12 Mile | 6V | Off-Grid Livestock Control

The Gallagher S20 Solar Fence Energizer delivers 12-mile / 40-acre clean fence coverage from a self-contained 6V solar unit — with built-in lightning protection, 360° T-post mounting, and up to 3 weeks of operation without sun — at $370.

• 3 Weeks of Operation Without Sun — Onboard rechargeable battery stores enough charge to keep the fence energized for up to 3 weeks without solar input; critical for extended cloudy periods or remote deployments where manual recharging is impractical.
• 12 Mile / 40 Acre Clean Fence Coverage — Covers up to 12 miles on a clean fence or 2 miles on a typical fence with vegetation contact; 40-acre clean coverage handles most small to mid-size homestead and farm perimeters.
• 360° T-Post Mounting — Full 360-degree rotation on T-posts allows precise solar panel orientation toward the sun regardless of fence line direction; maximizes daily charge harvest without repositioning the unit.
• Night Pulse Rate Reduction — Pulse rate automatically slows at night when livestock are less active; conserves battery power during low-activity periods and extends runtime between recharges.
• Built-In Lightning Protection — Integrated lightning protection safeguards the energizer electronics from surge damage; essential for exposed outdoor installations in open pasture environments.
• Super Tough, Waterproof, Drop-Resistant Casing — Designed to be left outside in all weather conditions year-round; no shelter or seasonal removal required — built for the demands of working farm and homestead environments.
• Complete Kit Included — Ships with rechargeable battery, solar panel, and lead set; ready to install out of the box with no additional components required.
