"Authentication technology standard management approach" resolves trade problems
In August 2009 by the Beijing-led Jianheng Certification Center, Hefei Sunlight Solar Energy Power Co., Ltd., Beijing Corona, China Electric Power Research Institute and other units are involved, according to the national commission "authentication technology standard management approach" and "authentication technology standardized management approach to the implementation details "requirements, co-drafted a certified technical specifications CGC/GF001: 2009" 400V following grid-connected photovoltaic inverter specific technical requirements and test methods ", and successfully at the national Certification and Accreditation Administration of the record, the record number To: CNCA/CTS0004-2009. In the grid-connected photovoltaic inverter national standard, industry-standard missing cases, the release of the certification specifications for China to implement grid-connected photovoltaic inverter to provide the healthy development of a scientific and rational technical basis.
The main technical specifications of the certification requirements include: performance and safety of two parts. Performance of some of China's power grid in accordance with the requirements of the development, including: power quality and protection. Among them, power quality testing project inverter efficiency, and net current harmonics, power factor, operating voltage, operating frequency, dc component, noise; the protection of functional testing project power fault protection, anti-anti-discharge protection, anti-polarity access protection, overload protection, anti-island test. Some refer to the relevant safety standards at home and abroad, including: electromagnetic compatibility and insulation withstand voltage, in which electromagnetic compatibility including: voltage fluctuation and flicker, launch requirements, immunity; insulation withstand voltage requirements in accordance with China's power sector development, including: insulation resistance and dielectric strength. Overall, the technical specification is in line with China's national conditions, with international advanced level of technical standards.
The product certification of grid-connected photovoltaic inverter is recognized by China's PV Industry
Currently, grid-connected photovoltaic inverter certification and implementation rules have been finalized and testing agencies have tested with the corresponding ability to work has become fully certified. Hefei sun 250KW, 100KW grid-connected inverter has passed the test, Beijing on good power supply, Beijing Corona and 5KW to 20KW, and grid-connected inverter is also about to complete the test. Germany, Austria, Spain and other enterprises are also ready to submit applications for accreditation.
