Patriot SolarGuard 1000 Solar Fence Energizer, 12 V

Power up to 40 miles (64 km) of fence with the Patriot SG1000, a 1.0-joule energizer for mid-size pastures and cattle. This fence energizer runs on solar, with a 12 V 7 Ah internal battery. Datamars rates it at 1.0 joules of output energy and 1.3 joules of stored energy, for up to 40 miles (64 km) of single-wire fence or about 140 acres (57 ha). Like all Patriot energizers it is low impedance, which helps push power through grass and weeds touching the wire.

Range figures are a guide for a single, weed-free wire; more wires, long runs and heavy vegetation reduce the distance. A good ground system matters as much as the energizer, so plan on at least three ground rods for most farm fences and test the fence with a voltmeter.
