1. About Testing Center

New Energy Testing Center was established in 2009 which aimed at testing and certification for

new energy products. This Testing Center covers an area about 3000 square meters and contains four

laboratories, High Power Product‘s Lab, Environment Test Lab, EMC Test Lab and Electrical Safety

Lab. It has 1MW global power grid environment, advanced testing equipments and test analysis

team rich in experience. Besides it is in accordance with the requirements of ISO/IEC 17025.

Quality policy

Scientific & just, accurate & reliable, normative, customer satisfaction

Testing must be done according to the following principle, test method should be scientific,

behavior must be just to ensure results are accurate and reliable, good specification and satisfied

testing service to clients.

Quality object
