he Home-use solar grid-connected system adopts distributed power generation way. It refers to the grid-connected power generation system with smaller configuration at the user site or near the power site to meet the needs of specific users. This way has got support and policy support from many countries, encouraging self-sufficiency in electricity consumption through the installation of solar power generation systems, and it can also sell the excess electricity to the government.

How does a home on-grid solar system work?

The main equipment of a distributed solar power generation system includes PV modules, PV array brackets, DC combiner box, DC distribution cabinet, grid-tied inverter, AC distribution cabinet, as well as control device and environmental monitoring device. Its operating mode is that under the condition of solar radiation, the PV modules converts the solar energy to electric energy, and feeds to the DC distribution cabinet through the DC combiner box, which is inverted by the grid-tied inverter to AC power and supply to the building's loads. Its surplus or insufficient power shall
