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.

From the perspective of corporate competition, it presents a unique trend. The United States ENPHASE is the leader of the micro -inverter market, with a market share of 76%. Domestic Yuneng Technology and Hemai shares have followed closely. The market share has continued to increase in recent years.

Specifically, as the first founder of the global miniature inverter, the leading manufacturer ENPHASE has been in a leading state in product technology for a long time. Since its first launch of the micro inverter in 2008 To 500W+.

In contrast, domestic micro -inverter manufacturers started later, and there was a certain gap between technology accumulation in the early stage of development and overseas leading manufacturers. After years of hard work, in recent years, domestic micro -inverter manufacturers have begun to catch up or even surpass international advanced levels in terms of product iteration and performance indicators, and have successively launched innovative products such as multi -body, three -phase, large current, and high power. On the whole, domestic micro -inverter manufacturers have achieved technological transformations from chasing to led, but the main sales markets are mainly overseas, such as Homai and Yuneng and other domestic heads of overseas markets. 70%.
In addition, unlike foreign companies, domestic micro -inverter manufacturers mainly adopt differentiated competition routes, and the cost -effective advantage of products is outstanding. For example, overseas micro -inverter manufacturers such as EnPhase have always maintained high -end routes. The product is mainly single -phase single solution. A miniature inverter usually only connects a component, and the single -wal cost is high. Domestic manufacturers have no advantages in overseas channels and brands. Therefore, they pay more attention to the cost -effectiveness of the product itself. The product system is gradually upgraded by the initial monopoly plan. More than 3KW has a significant advantage in the single -wal cost.

The development prospects of miniature inverters
In terms of global markets, photovoltaic buildings have gradually become mainstream application scenarios. The acceptance of component -level electronic equipment represented by miniature inverters has continued to increase, and related compulsory measures are expected to further promote the market for miniature inverters. The industry is transforming from a group -type inverter to a component -level inverter. Micro inverters and power optimizers are expected to become one of the mainstream directions of the next generation of inverters.
In terms of domestic market, in terms of policies, relevant documents such as "Notice on Strengthening the Safety Work of distributed photovoltaic power generation (Draft for Opinions)" and other related documents have clearly explicitly encouraged the development trend of miniature inverters. The device will benefit further; at the level of demand, with the development of the entire county's promotion work, central state -owned enterprises replaced private enterprises to become the main developers of distributed power stations. The expansion of terminal demand is expected to drive the penetration rate of domestic miniature inverters.
At the end
In summary, relying on the strong domestic power electronics and photovoltaic industry foundations, domestic miniature inverter manufacturers have certain advantages in the control chain control. European and American manufacturers represented by ENPHASE are mainly reflected in the level of technology research and development, product design, software algorithms, etc. The production and supply chain links mainly rely on China, Mexico, India and other countries.
In the long run, with the continuous expansion of the production and sales scale of micro -inverters, the efficiency of the production end and the control capacity of the supply chain will become more important. In these areas Micro -inverter manufacturers are expected to re -engraved the traditional inverter's domestic replacement.
