Solar electric generator

Solar Electric GeneratorLiberty Solar Box is a patented innovation in the domestic solar water heating industry. The product is a solar electrical generator, which uses PV panels instead of regular solar thermal collectors independent from the grid voltage. A typical residential application uses only 1.2 kW to 1.45 kW of light PV panels for an 80-gallon electric tank. The Liberty Solar Box is not only a power supply, but also a digital impedance transformer that transfers the water heater element impedance according to the sun energy density. The more sun energy, the lower the impedance, and the higher the heat transfer to the water tank. As little as three or four light PV panels on a roof can supply a family of four with an ample amount of hot water. In this new PV-SWH system, there are no moving parts—no pump, no copper, no leaks, no plumbing, it doesn’t freeze, and the system doesn’t require fluid or glycol.
