Off-Grid Power for Remote Pastures
The S400 solar fence charger is built for fencing systems in areas with no access to mains power. In ideal conditions, the S400 powers up to 60 miles of single-wire or 20 miles of multi-wire fencing, ideal for rotational grazing and remote livestock management. Portable, High-Output Solar Energizer
Built with an integrated solar panel and 12V battery, this all-in-one electric fence energizer is easy to transport, set up, and operate. Perfect for livestock containment, wildlife exclusion, and pasture control. Consistent Voltage Through Light Vegetation
Engineered to deliver steady, reliable voltage—even through grass or seasonal weed growth. The S400 keeps your fence hot and effective, reducing power drop along long or overgrown fence lines. Smart Energy Management with Dual Power Modes
Gallagher’s intelligent power system offers pulse timing to conserve energy and extend battery life. Set fast pulse day and night, or use night mode to reduce output when animals are less active. Durable, Weather-Resistant Build
Designed for tough outdoor use with a water-resistant housing, built-in lightning protection, carry handle, and 360° mounting options. Backed by a full 3-year manufacturer’s warranty for peace of mind. Maintains Power Through Light Vegetation
The S400 Solar Fence Energizer delivers consistent, reliable voltage across your entire fence line—even in areas with light grass, weeds, or seasonal growth. Its high-output design ensures your livestock fencing remains effective and uninterrupted, reducing voltage drop caused by minor vegetation contact. The Gallagher S400 Solar Electric Fence Energizer is a high-output, portable energizer designed for medium-sized fencing systems in remote or off-grid areas. With 4.0 joules of stored energy, the S400 powers up to 60 miles of single-wire or 20 miles of multi-wire fencing — ideal for rotational grazing, strip grazing, wildlife exclusion, and general livestock containment across 120–280 acres. This all-in-one unit includes a built-in solar panel, rechargeable 12V battery, carry handle, and weather-resistant casing. Gallagher’s intelligent battery management system delivers consistent voltage through light vegetation and allows the energizer to operate for up to one week without sunlight. Choose between Wildlife Mode (fast pulses day and night) or Full Power Mode (slower pulses at night) to conserve energy when animals are less active. The unit mounts in any direction with 360° post compatibility and includes built-in lightning protection, a battery status indicator, and a fence leadset. Fully integrated and easy to use, the S400 is the ideal solar-powered fence charger for farms and ranches of any size.
