Solar Powered Fence Chargers
Our four solar-powered electric fence chargers (the Fi-Shock SS-740, Power Wizard PW50S, Parmak Solar Pak 6, and Parmak Solar Pak 12) are all low-impedance units that come in weather-proof cases with installation instructions, a battery, a solar panel, and a limited two-year or 3-year manufacturer's warranty (the PW50S comes with a 3-year warranty). The SS-740 and PW50S, with an actual output of about 0.05-0.06 joules, are suitable for use with small dogs. However, if these chargers are used with low wires, care must be taken to keep those wires out of contact with weeds or other vegetation, because these can draw the charge off the fence and stop it from shocking anything. The Solar Pak 6, with a rating of about 0.25 joules, is a bit stronger; and the Solar Pak 12, rated at 0.5 joules, is stronger still and can cope with a significant weed burden.
If it starts fully charged, the SS-740 will keep operating for 7 to 10 days in total darkness, while the Solar pak 6 and Solar Pak 12 will both do so for an impressive 21 days. As indicated in the table below, replacement batteries and battery rechargers are available for all of these products. We have little demand for Solar Pak 6 or Solar Pak 12 replacement batteries, indicating that these batteries hold up very well. The average life of the SS-740 battery is estimated at 2 to 5 years.
