Shenzhen Research Institute, the State Key Laboratory of power system, was established in October 2000. It is the first State Key Laboratory in Shenzhen officially approved by the Ministry of science and technology of the people's Republic of China. Shenzhen Research Institute of State Key Laboratory of power system has solar power generation experimental platform (water pumping system, grid connection and energy storage), wind power water extraction test platform and power electronic product development test platform. According to the technical development and market demand, taking inverter technology as the core, actively cooperating with enterprises, we have developed a series of products such as special frequency converter for permanent magnet synchronous motor, special inverter for solar energy / wind energy lifting, solar grid connected power generation inverter, and carried out interdisciplinary research with the environmental engineering laboratory and green chemical power laboratory in the Institute.
