On December 30, 2022, the R&D department of the company announced a major success, with six energy storage product patent applications approved at once (1. a solar off grid inverter with intelligent switches; 2. a bidirectional energy storage converter (100KW) control system; 3. A double-sided heat absorbing solar energy device applied to photovoltaic power generation; 4. A distributed substation energy storage converter (PCS); 5. A distributed substation energy storage fire protection system; 6. A distributed substation energy storage temperature control system, The six energy storage product patents obtained this time will play an important role in promoting the development of the company's energy storage projects. Vigorously developing the energy storage industry is one of the major decisions made during the 14th Five Year Plan period of the country. Our company actively responds to the national call and positions the development of energy storage products as the company's key research and development direction. In the past few years, the company has invested a large amount of manpower, material resources, and financial resources, closely following the development trend of the energy storage industry, and has successively developed a series of energy storage products with industry-leading standards, which have been put into the market. It has cooperated with the State Grid of China and multiple power generation groups, and has established pilot projects for distributed energy storage power stations with photovoltaic+storage+grid connection in multiple provinces and cities. It has also developed multiple innovative achievements such as "orderly grid connection, remote monitoring, and energy dispatch of photovoltaic", It has brought good economic, social, and management benefits to customers and has received unanimous praise from them. The company will continue to leverage its technological advantages, accelerate the exploration and research of new energy storage technologies and models, and continuously contribute to the development of the country's energy storage industry.
