SOLAR POWERED — The attached solar panel will recharge the 12V battery on sunny days. DC electric fence chargers require no outlet and are a popular choice when 110V power is not easily accessible. When fully charged, the 15Ah battery provides reserve energy for 4 sunless days—so you can be sure your fence remains effective day and night. STOP PREDATORS — When connected to an electric fence (e.g. netting, polywire, tape), its “shock effect” is effective against predators such as coyotes, stray dogs, bears and foxes. Or use with garden and wildlife fences to keep out deer, raccoons, woodchucks, rabbits, opossums and skunks. Electric fence is a pain barrier, not a physical barrier. Animals conclude the fence itself is painful—and then avoid it. PORTABLE — All-in-one unit is quick to set up and operable in minutes. No buried lead-out wires or underground cables required! RUGGED DESIGN — Glass solar panels are more durable than thin-film, and the sealed enclosure keeps out moisture and insects. DUAL-MODE OUTPUT – Energy Saver mode reduces the joule output to conserve energy. This is useful for short fences, or for “clean” fences with low resistance. Solar powered 0.8 output joule energizer for electric fences. The portable all-in-one SolarStop 80 can be used to contain sheep, goats, poultry, swine, cattle, horses and other livestock. Keeps out ground-based predators such as coyotes, stray dogs, bears and foxes.
