Metropolitan Industries and its Ion Products brand announces its latest version of Sumpro availability, an intelligent battery backup system with a premier fully automatic auxiliary power source. Performance-tested for optimal functionality, Sumpro systems can be used in conjunction with pumps with a variety of horsepower ratings. Sumpro systems install in minutes as users simply plug units into a standard dedicated wall outlet. When a power failure is detected, Sumpro will automatically supply standard household electricity to any connected appliance until utility power is restored. It can also work in conjunction with green technologies, such as solar and wind inputs.
