As the proportion of new energy sources becomes higher and higher, the grid's requirements for the friendliness of photovoltaic power plants are also increasing. During this period, the bridge between the photovoltaic power station and the power grid, the position of the photovoltaic inverter, became more and more important. New inverters can adapt to the new requirements of the power grid, and early inverters must undergo technological transformation. That is, the original manufacturer upgrades the functions of the old machine.

However, when the inverter needs technical transformation, the problem comes: the original manufacturer can no longer find it! According to statistics, more than 95% of inverter brands that have appeared on the market since 2009 have disappeared!

1. Those disappearing inverter companies

In July 2019, after ABB announced its withdrawal from the photovoltaic business, many industry insiders felt that the photovoltaic inverter market was surging. Five major international giants, including Emerson, Siemens, GE, Schneider and ABB, had closed their related businesses. In October 2019, Maoshuo Power provided a detailed response to the inquiry letter sent by the China Securities Regulatory Commission, which pointed out that the photovoltaic inverter business dropped by 88.95%, which made people worry about the prospect of Maoshuo Power;

There are many domestic enterprises that have closed inverter business, as can be seen from the number of SNEC exhibitors over the years:

At the 2012 Shanghai SNEC exhibition, as many as 439 inverter-related manufacturers;

In 2013, only 286 exhibitors remained;

In 2018, about 80 inverter companies exhibited.

China's photovoltaic inverter reshuffle is very tragic, experienced two rapid development periods in 2009 and 2016, but also accompanied by two major reshuffles in 2013 and 2018, during which 95% of the inverter brand has also died . In 2019, there were not many inverter companies that survived the post-531 Winter Deal. There are currently only 20 or so active companies in the market.

Table: Inverter companies that were once famous and now quit

The picture above is a relatively large second-tier or quasi-first-tier brand that has been withdrawn from the inverter business or merged and acquired in recent years. The average life span is about 7 years; there are many third-tier and fourth-tier companies that enter and exit quickly. , The average life expectancy may be about 3 years.

2. Enterprise life is more important than inverter life

A number of inverter companies have said: At present, the shipment of technological transformation has accounted for one-third of the total.

The so-called technological transformation shipment is that the inverter of the early photovoltaic power plant has a small fault, cooperates with the grid upgrade and other problems, and even the equipment may still be within the five-year warranty period, but the original inverter manufacturer has closed down or exit Inverter business, unable to provide services to customers. Therefore, customers have to purchase new inverters.

They are also important parts of photovoltaic power plants, but the procurement points of components and inverters are very different. For power station investors, a power station and component manufacturers usually only meet once, even if the component manufacturers are no longer available, they can purchase other components to replace;

The inverter is the interface and output terminal of all data of the photovoltaic power plant. No matter which part of the photovoltaic power plant has problems, the owner first thinks of the inverter company. According to big data statistics, during the entire 25-year lifespan, the owner may have to deal with inverter manufacturers more than five times.

It can be seen that under the current situation that the quality and performance of inverter products are very mature, the life of inverter companies is even more important than the life of inverters.

For power plant owners, the importance of choosing a partner with long-term value even exceeds the product itself. When purchasing inverters, the inverter companies you choose to cooperate with can at least survive to cover the inverter's life cycle.

3. The evergreen tree in the inverter company

The life of inverter companies is so important. Which inverter companies have been serving everyone?

Table: Inverter companies with the longest life

As can be seen from the above table, the enterprise that has completed the entire life cycle of the inverter has only been a Sungrow power source for the inverter in 1997. Close to this figure are companies such as Kstar, Xiamen Kehua, TBEA, Chint New Energy, Jinlang, Gurivat, Goodway and others.

The survival history of an enterprise is only one aspect. When choosing a partner, it is also necessary to consider whether the enterprise can continue to operate in the future, from the multi-dimensional evaluation of R & D strength, product quality, financial status, growth, entrepreneur background and personal charm; It is also necessary to consider whether the style of the enterprise is in line with the future development trend of the market.
