Solar cells and inverters
A solar inverter is really a converter, though the rules of physics say otherwise. A solar power inverter converts or inverts the direct current (DC) energy produced by a solar panel into Alternate Current (AC.) Most homes use AC rather than DC energy. DC energy is not safe to use in. . The solar process begins with sunshine, which causes a reaction within the solar panel. That reaction produces a DC. However, the newly created DC is not safe to use in the home. . Oversizing means that the inverter can handle more energy transference and conversion than the solar array can produce. The inverter. . Choosing a solar power inverter is a big decision. Much of the information about selecting an inverter has to do with the challenges that a solar array on your roof would have.
