The direct current generated by the solar module is converted into alternating current by the inverter, which is then supplied to the load and connected to the grid. In this way, while meeting the household load, excess electricity can also be sold into the grid.

Independent systems that do not depend on the grid power. As long as the sun is satisfied, the off-grid system can work and provide electricity independently.

Microgrid system is an autonomous system capable of self-control, protection and management, which can not only be connected to the external power grid, but also operate in isolation, which solves the problem of the distributed power grid to a great extent, promotes the large-scale access of distributed power and renewable energy, and is a smart grid system that provides efficient supply of various energy forms for load and realizes the active distribution network.
