Microinverters, as core components of photovoltaic power generation, have garnered significant attention.

Due to the rising global demand for renewable energy, the installed capacity for new energy generation has been rapidly increasing. The microinverter market is expected to continually expand in the coming years, presenting vast market prospects.

Data indicates that in 2021, global microinverter shipments reached 3.61GW, growing by 58.3% year-on-year. In 2022, global microinverter shipments reached approximately 7.93GW. It's projected to reach 13.39GW by 2023.

Regionally, microinverters have a strong geographical presence globally. Shipments in North America account for around 70%, while Europe holds about 15%-20%. Other regions in the Asia-Pacific hold a relatively smaller share. In terms of market share, Enphase, an overseas company, leads, while Chinese companies such as HEMAI, YUNENG, and DEYE are rapidly rising.
