The solar photovoltaic power system connected to the public grid is called an on-grid photovoltaic power generation system. The system structure includes solar battery arrays, DC/DC converters, DC/AC inverters, AC loads, transformers, and other components.
The grid-connected photovoltaic power generation system can convert the DC power output by the solar cell array into AC power with the same amplitude, frequency, and phase as the grid voltage, realizes the connection with the grid, and transmits electricity to the grid. When sunshine is strong, the system supplies the AC load with excess electric energy while feeding it into the grid; when sunshine is insufficient, it obtains electrical energy from the grid.
