Chinese PV manufacturer Sungrow has inagurated a new 10m Anechoic chamber with high power distribution capacity and will be used for testing photovoltaics (PV) and energy storage system (ESS) products.
The anechoic chamber, also known as electromagnetic compatibility (EMC) chamber, will facilitate EMC tests for new products and help develop EMC solution technologies and products accordingly.
The chamber, which cost around 5 million USD and took about two years to plan and construct, covers an area of over 700 m2 and has an internal height of 7.8m. As the first of its kind in the industry, it can test large electrical equipment like a PV inverter turnkey station as large as 5MW and as heavy as 20 tons at a distance of 10m which is required by relevant standards. By employing the ROHDE & SCHWARZ EMC testing system, the chamber can reach test accuracy equal to that of major third-party testing organizations.
"This anechoic chamber, as a key testing facility, symbolizes the technology leadership of Sungrow. It can conduct EMC tests for PV inverters, storage inverters, and other electrical equipment," said Thomas Wang, director of Sungrow testing center. "We will build on our current advanced testing capability and enhance our testing system by introducing more state-of-the-art equipment and adopting higher testing standards."
Sungrow has always emphasized the importance of product process control and technology upgrading. Its independent testing center, equipped with the most advanced testing platforms, is now accredited by UL, CSA, TUV SUD and TUV Reheinland as their witness laboratory. "The EMC chamber strengthens our capability for product tests and will help us develop more efficient and reliable products for our customers worldwide," said Professor Renxian Cao, President of Sungrow.
