Gallagher M5800i Electric Fence Charger 58 J AC Energizer with External Control & Display Panel

The Gallagher M5800i is a professional-grade AC-powered fence energizer built for large farms and ranches that need high-output, intelligent fence management across extensive multi-wire fence systems. Delivering 58 stored joules, the M5800i is capable of powering up to 87 miles of fence covering approximately 2,200 acres of multi-wire fence under good conditions with proper grounding and minimal vegetation contact. Gallagher's iSeries adaptive technology actively monitors changing fence conditions and adjusts voltage output in real time pushing more usable power through fence faults and vegetation load to maintain effective voltage across the full length of your fence line. An included external control and display panel mounts separately from the energizer and can be positioned up to 164 feet (50 meters) away, giving you convenient access to fence performance data from a practical outdoor location without returning to the unit itself. For operations requiring around-the-clock oversight, the M5800i is compatible with Gallagher iSeries accessories and the Gallagher Ag Devices mobile app, which delivers real-time fence performance data, fault alerts, and remote on/off control directly to your phone. Built to perform in extreme temperatures with built-in lightning protection, the M5800i is engineered to hold up in the demanding conditions that large agricultural operations face year-round. Backed by Gallagher's 3-year manufacturer's warranty and U.S.-based customer support, the M5800i is a dependable, high-performance solution for serious large-scale fence management.
