What is grid-connected photovoltaic electricity generation?

Grid-connected photovoltaic power generation means that the DC energy generated by solar modules is converted into AC energy that meets the requirements of the municipal power grid via a grid-connected inverter and then directly connected to the utility grid. It can be divided into grid-connected power generation systems with and without batteries. Grid-connected power generation systems with batteries are dispatchable and can be on-grid or off-grid as needed. They also have the power backup function. They can provide backup power when the grid is down for any reason. Grid-connected photovoltaic power generation systems with batteries are often installed in residential buildings. Grid-connected power generation systems without batteries do not have distributed functionsand backup power and are typically installed on larger systems.
