With a massive 58 joules of stored energy and 40 joules of output, this i Series unit can energize up to 430 miles (2,700 acres) of fencing—making it ideal for large pastures, multi-wire systems, and demanding livestock operations.
Equipped with adaptive i Series technology, the M5800i dynamically regulates voltage output to push maximum power down the fence line and overcome vegetation or minor shorts.
