The Sun can generate systemIt is divided into off-grid power generation system,Grid-connected power generationSystem and distributed generation system:

 

 1, the off-grid power generation system is mainly composed ofsolar cell module, controller,batterycomposition, such as the output power supply is AC220Vor110V, also need to configure the inverter.

 

 2,Grid-connected power generationThe system is that the direct current generated by the solar modules is converted into alternating current that meets the requirements of the mains grid through the grid-connected inverter and then directly connected to the public grid.

 

      _cc781905-5cde-3194-bb3b-136bad5The system has centralized large-scale grid-connected power stations, which are generally national-level power stations. The main feature is that the generated energy is directly transmitted to the power grid, and the power grid uniformly allocates power to users. However, this kind of power station has not developed much due to its large investment, long construction period and large area. The decentralized small grid-connected power generation system, especiallyPV building integrationThe power generation system is the mainstream of grid-connected power generation due to the advantages of small investment, fast construction, small footprint, and strong policy support.  3, Distributed power generation system, also known as distributed power generation or distributed energy supply, refers to the configuration of a smaller photovoltaic power supply system at the user site or near the power site to meet the needs of specific users. demand to support the existing distribution networkEconomic Operation, or satisfy both requirements.

　　 Distributed photovoltaic power generationThe basic equipment of the system includes photovoltaic cell components, photovoltaic array supports, DC combiner boxes, DC power distribution cabinets, grid-connected inverters, AC power distribution cabinets and other equipment, as well as power supply system monitoring devices and environmental monitoring devices. Its operation mode is that under the condition of solar radiation, the solar cell module array of the photovoltaic power generation system converts the solar energy into the output power, and sends it to the DC power distribution cabinet through the DC combiner box, and the grid-connected inverter converts it into AC power to supply the building itself. Loads, excess or insufficient power are regulated by connecting to the grid.
