Solar power generation system
- May 10, 2018 -

The solar power system consists of a solar battery, a solar controller, and a battery (group). If the output power is AC 220V or 110V, you also need to configure the inverter.

Solar power generation systems are divided into off-grid power generation systems and grid-connected power generation systems:

1. Off-grid power generation system. It is mainly composed of solar battery components, controllers and batteries. To supply power for AC loads, AC inverters must also be configured.

2. The grid-connected power generation system is the direct current generated by the solar module and is directly converted into the public power grid after the grid-connected inverter is converted into the alternating current that meets the requirements of the mains grid. Grid-connected power generation systems There are centralized large-scale grid-connected power stations that are generally state-level power stations. The main feature is that the generated power can be directly transmitted to the power grid, and the power supply can be provided to the users through the unified deployment of the power grid. However, this kind of power station has a large investment, a long construction period, and a large area, but it has not yet achieved much development. The decentralized small-scale grid-connected power generation system, especially the photovoltaic building integrated power generation system, is currently the mainstream of grid-connected power generation due to its advantages of small investment, quick construction, small land occupation, and strong policy support.
