M5800i Fence Energizer System

“Incredible power combined with 24/7 monitoring for complete peace of mind”


The M5800i is the world’s 3rd most powerful energizer! With a massive 58 joules (40 joules max output energy) stored energy and all the smarts of the i Series system, the M5800i Energizer is a serious contender in the high power energizer market and best in class for electric fence energizers in the 30-40 output joule range!

  • Delivers maximum power with advanced monitoring capabilities for the maximum control of medium to large security fence network applications.
  • Working together the i Series system (Energizer, Energizer Controller, Fence Monitor & Remote/Fault Finder) provides fence information at a glance and if it detects any faults, leads you directly to them, saving you hours of searching.
  • M5800i – Powers up to 5,000 to 7,000 meters of free standing electric fencing (9-12 live wire strands).
  • The M5800i energizer will maintain up to 8.5kV at 100 ohm load (heavy fence load) and up to 6.1kV at 50 ohm load (extreme fence load) !!!
  • Mains powered (220-240v) with quality modified inverter (600watt / 12v) battery backup.
  • Compatible with SMS
  • Energizer Controller which enables alarms to be sent to your phone, fence performance status checked and energizer turned on/off via text message.
  • Energizer can also be connected to an Alarm System which monitors a section of fence and drives external strobe lights, sirens or alarms panels if the circuit is broken eg. gate opened or a wire cut.
  • M5800i security energizer design brings together advanced security features and game animal control combined and is the ideal choice for longer series-parallel fencing systems which require monitoring.
  • Advanced lightning protection.
  • Fully modular for quick servicing.
