The Gallagher S12 Lithium Solar Fence Energizer is a compact, portable solar-powered charger designed for small pastures, rotational grazing, garden protection, pet fencing, and nuisance animal deterrence around suburban, rural, and hobby farm properties. Delivering 0.12 stored joules, the S12 powers up to 4 miles of clean fence and covers approximately 18 acres under good conditions with proper installation and minimal vegetation contact. Its built-in high-efficiency solar panel, smart digital charge controller, and long-lasting lithium battery help provide dependable day and night fence power without needing access to plug-in power. Gallagher's unique post-mount earth system allows the unit to mount directly onto an unpainted steel rod or ringtop post up to 0.5 inches thick, with the post acting as both the stand and earth connection when installed as directed. Built with a water-resistant housing, built-in lightning protection, and backed by Gallagher's 3-year manufacturer's warranty and U.S.-based customer support, the S12 is a practical electric fencing solution for livestock, pets, gardens, and property protection.Includes Fence Lead
