The energy crisis is superimposed with the energy revolution, and the micro -inverter ushered in a rapid development stage in the photovoltaic market. In the context of the expansion of the micro -inverter market and the ENPHASE family, which domestic micro -inverter manufacturers will be expected to re -engravon the traditional inverter's domestic alternative?
Development status of miniature inverters
As we all know, the inverter is an important part of the photovoltaic system, which mainly plays the role of the transition and the maximum power point tracking.

The micro -inverter is also called a component -class inverter, which belongs to one of the photovoltaic inverters. It is mainly used in a distributed scenario with smaller power generation scale, which is a typical application of component -level power electronic technology in photovoltaic power generation systems. Compared with the traditional centralized and group -type inverters, it has higher operating efficiency and better safety. It is mainly used in the current rapid development of household power generation.

Over the years, with the continuous growth of global photovoltaic installation machines, distributed power stations represented by photovoltaic photovoltaic photovoltaics have gradually become the main force of photovoltaic installation machines. The proportion of photovoltaic installations in global households has been increased for 5 consecutive years, and it has reached 26%in 2021. Among them, the proportion of photovoltaic installations in the Chinese market has increased from 1.7%in 2016 to 39.4%in 2021.

From the perspective of domestic and foreign markets, due to security policy requirements, miniature inverters have become the mainstream choice for households to use distributed photovoltaic power stations.

From a economic and practical perspective, the initial investment cost of micro -inverters is higher, but the efficiency of high systems is higher than the long -term economy in the application scenario of household installation.

In general, the global mini -inverters, especially the North American market, grow rapidly. The global shipping volume reached a record high in 2021, reaching 3.61GW, a year -on -year increase of 58.3%. However, due to the slightly higher cost of single -wwws and restrictions on application scenarios, the penetration rate of global micro-inverters in the distributed market in the past remained between 2%-5%, and the market size was about 8.88 billion yuan.
In the North American market, distributed photovoltaic starts earlier, policies emphasize factors such as DC electricity safety, mature subsidy plans, unstable energy supply, and soaring electricity prices of residents. Essence Relatively speaking, the Chinese miniature inverter market is still in the early stage of development, and the market penetration rate is about 0.1%, and there is huge room for development.

Micro -inverter market competition pattern
From the perspective of the area distribution of global micro -inverters, the main terminal demand market is concentrated in Europe and the United States. Among them, due to the unstable energy supply, North America and Europe are the two major micro -inverters markets at present, with mature policies and strong user payment capabilities. The ability is relatively weak, so manufacturers with cost advantages will occupy a competitive advantage.
