The Scientific Research Project of DHC Photovoltaic Inverter has Passed the Evaluation of Provincial Department of Science and Technology2011-05-31

Nowadays, the scientific research project of DHC 5kw single-phase grid-connected photovoltaic inverter has passed the evaluation of scientific and technological achievements organized by Sichuan Provincial Department of Science and Technology.

Grid-connected photovoltaic inverter is another leading product for DHC to march into new energy market. Since the successful development of wind turbine power inverter in 2009, the DHC has further speed up its pace in the research and development of independent innovation products. Depending on the successful application experience accumulated in the past many years and advanced technical process of high power and voltage inverter, the scientific research project of 5kw single-phase grid-connected photovoltaic inverter has created outstanding achievements of completing prototype trial-production,  putting into operation by users and acquiring CE and TUV test and certification in that same year.

Based on its self-owned independent intellectual property rights technologies, the project puts forward advanced anti-islanding detection algorithms and application technology solution, making sure that the products possess high technical and safety performance. After almost one year's examination and test of site operation, it is proved that the products of this project have met the requirements of safe and reliable operation and remarkable energy conservation and pollution reduction.

The evaluation meeting has been presided by the Scientific and Technological Achievements Office of Provincial Department of Science and Technology, the Evaluation Committee of Project Technology was made up of 7 specialists who separately from Provincial Power Electronics Society, Southwest Jiaotong University, University of Electronic Science and Technology of China, Sichuan University and users. Through on-the spot inquiries, the specialists has given affirmation in the innovation level, novelty and product application effect of the project technology, considered that the project technology has reached an international advanced and domestic leading level, approved that the project has passed achievement evaluation, and at the same time suggested a further promotion and application of this project achievement in new energy field.
