Distributed photovoltaic power system, also known as decentralized power generation or distributed energy supply, refers to the configuration of smaller photovoltaic power supply systems at site or near the site to meet the needs of specific users, to support the economic operation of existing distribution networks, or to meet the requirements of these two aspects at the same time.
The basic equipment of the distributed photovoltaic power generation system includes the photovoltaic cell module, the photovoltaic square array bracket, the DC converge box, the DC distribution cabinet, the grid connected inverters and the AC distribution cabinet, as well as the monitoring device of the power supply system and the environmental monitoring device. Its operation mode is that under the condition of solar radiation, the solar cell component array of the photovoltaic power generation system converts the output of the solar energy into the DC distribution cabinet through the DC converge box, and supplies the building itself by the inverting inverters of the grid connected inverter, and the surplus or insufficient electricity is transferred through the grid.
