The frequency converter is a high-tech product with high technological content, high added value, and high efficiency and return. Technology is not a barrier for China's and foreign inverter industries, and stability and product performance have gradually become the main technical problems faced by various manufacturers. Foreign brands are relatively satisfied with the failure rate, component quality, and ultra-high-power products due to relatively mature product technology and relatively rich industrial application experience. However, with the continuous development of local brands, this gap has gradually narrowed. Where is the gap between China's domestic inverter companies and foreign countries?
First of all, it is difficult to develop technology. At present, many inverter manufacturers in China are investing large amounts of manpower and material resources in the research and development of high-voltage inverters, and strive to occupy the commanding height in frequency inverter technology. In spite of this, the core components of the inverter have always depended on imports, which has become a bottleneck restricting domestic production of the inverter.
Secondly, the inspection period is long, domestic enterprises have a short history of development, and inverter products generally have a maturation period of about 3 years. The quality is reliable and the performance is stable. It requires the customer to use the time test. Since most local companies have not established a long history, the product line is still improving. Many new products have a shorter time to market, and it is difficult to compete with long-established international brands in terms of product maturity and brand awareness. In addition, due to the special nature of China's low- and medium-voltage inverter market, foreign brands are pre-emptive, which has a negative impact on domestic brands participating in market competition.
In addition, the product performance index is low, in the initial stage of the domestic brand start, there are indeed some product quality, but the reliability and stability is poor, affecting the reputation of domestic brands. In recent years, with the growth of local companies and the improvement of their overall strength, the reputation of domestic brands has been significantly improved. However, to completely change the overall impression of users, it still needs the efforts of production companies and the test of time. In product price, brand, performance, after-sales service, delivery date and other factors affecting the purchase of domestic inverter products, product performance indicators become the preferred element. Therefore, improving product performance, especially improving the energy efficiency of products, has become an important task for all production companies.
With the advancement of domestic manufacturers' technological progress and quality stability, coupled with the advantages of services and prices, it is expected that the market situation of high-end products monopolized by foreign manufacturers in the next few years will change.
