DC Solar Power System Solar Controller
Solar power generation system consists of solar cells, solar controllers, batteries (group) composition. If you want to make the output power of 220V or 110V AC, you also need to configure the inverter.
Solar power generation system is divided into off-grid power generation system, grid-connected power generation system and distributed power generation system:
1, off-grid power generation system mainly by the solar cell components, controllers, batteries, such as the output power for the AC 220V or 110V, also need to configure the inverter.
2, grid-connected power generation system is generated by solar modules DC power through the grid inverter into the AC power grid in accordance with the requirements of the direct access to public power grid. Grid-connected power generation systems are centralized large-scale grid-connected power plants are generally state-level power plants, the main feature is the power generation can be directly transported to the grid, the unified allocation of power to the user power supply. But this power plant investment, construction period is long, covers an area of large, not much development. The decentralized small-scale grid-connected power generation system, especially the integrated photovoltaic power generation system, is the mainstream of grid-connected power generation due to its small investment, fast construction, small footprint and strong policy support.
3, distributed generation system, also known as decentralized power generation or distributed energy supply, refers to the user site or near the electricity site configuration of the smaller photovoltaic power supply system to meet the needs of specific users to support the existing distribution network Economic operation, or at the same time to meet these two requirements.
The basic equipment of the distributed photovoltaic power generation system includes the components of the photovoltaic cell, the PV matrix bracket, the DC converter box, the DC power distribution cabinet, the grid inverter, the AC power distribution cabinet and so on. In addition, the power supply system monitoring device and the environmental monitoring Device. Its operating mode is in the solar radiation conditions, the photovoltaic power generation system, the array of solar cells will be converted to solar energy output, through the DC converter box into the DC distribution cabinet, by the grid inverter inverter AC power supply The building itself loads, excess or insufficient electricity is regulated by connecting the grid.
