A photovoltaic inverter changes direct current (DC) from a solar cell array to alternating current (AC), synchronizes with a grid and feeds the energy into the grid, mostly a public utility grid. The opposite to these grid connected systems are island systems, which build their own grid and keep it running (keeping phase and frequency stable).

Special procedures to deal with the array are needed, and should be discussed here in future:
