Solar Grid-connected System

The photovoltaic grid-connected power generation system is mainly composed of a solar array, a DC / AC inverter, a computing device, and a power distribution system. When there is sunlight, the inverter inverts the DC power generated by the photovoltaic system into sinusoidal AC power. The generated AC power can be directly supplied to the AC load, and then the remaining power is input to the power grid, or the entire power generated is directly fed into the power grid. In the absence of the sun, all power for the load is supplied by the grid.

Grid-connected power generation systems are generally divided into "ground centralized grid-connected systems", "ground string-type grid-connected power generation systems", "distributed commercial grid-connected power generation systems", and "distributed household grid-connected systems".
