Gallagher M5800i Energizer
Commercial-Grade Power with i Series Intelligence — Gallagher M5800i Energizer
The Gallagher M5800i is built for large commercial operations where fence performance can't be left to chance — 58 stored joules and 40 output joules powering up to 430 miles of multi-wire fence across up to 2,200 acres. Adaptive technology continuously monitors fence conditions and adjusts voltage output to push through faults, vegetation load, and long runs without dropping below effective levels.
The i Series external control and display panel mounts separately from the energizer, giving you fence performance data in a convenient location — and with a WiFi Gateway and the Gallagher Ag Devices app, you get real-time fence monitoring and control from your phone.
