Does photovoltaic power generation require an inverter
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.
