In the inverter market, domestic brands still lag behind their international counterparts in terms of technology, manufacturing capabilities, industrial design, and financial strength. Despite the significant presence of local brands—accounting for over 70% of the market—domestic companies hold only about 24% of the overall market share. While the growth of Chinese inverter brands is accelerating, the majority of the market remains dominated by a handful of European, American, and Japanese companies. Industry experts believe that the Chinese inverter market has just begun to take shape, with strong development potential. It is expected that the market will not reach saturation for the next decade, and the annual growth rate will stay above 15%. However, the global financial crisis in 2009 caused a slowdown in market expansion.
The supporting industry for inverters in China is still relatively weak. Compared to leading global players like Siemens and ABB, domestic brands face challenges across multiple dimensions, including technological innovation, production quality, and brand reputation. In the low- and medium-voltage inverter market, foreign brands continue to dominate, holding around 76% of the market share—similar to levels seen in 2007. Increased investment in infrastructure projects, which are traditionally strongholds for Western brands, further strengthened the position of top foreign companies in 2008. Most local manufacturers focus on basic V/F control products, while advanced technologies such as vector control remain largely unexplored by domestic firms. Although some well-established Chinese brands, like Shenzhen Inventronics and Chengdu Hope Senlan, have made progress in developing vector inverters and achieved success in specific applications, their product ranges are still limited compared to international competitors.
Despite this, the market share of local brands has been growing rapidly, and the influence of key domestic players is increasing. However, the top ten foreign brands still control the majority of the market, with companies like Siemens, ABB, Mitsubishi, and Yaskawa maintaining a strong presence. The Chinese inverter market was initially driven by foreign brands, which held over 90% of the market share until around 2000. As domestic brands gained traction, their market share gradually increased. By 2005, domestic brands had reached about 15% in the low- and medium-voltage inverter segment. This grew to 20% in 2006 and 24% in 2007. In 2008, due to the financial crisis, many large infrastructure projects were delayed, and domestic brands struggled to make further gains, keeping the market share at around 24%.
