TÜV SÜD to offer storage system certification


Citing the global expansion of renewable energies and the decentralization of electricity that is driving development of stationary battery storage systems, TÜV SÜD is offering a new Renewable Energy Storage Systems (RESS) certification program.

German testing and certification company said the process would allow examination of the safety and performance of such systems and ensure greater transparency in a rapidly growing market.

"The global market for stationary battery storage systems is developing extremely dynamically," says John Brey, managing director of TÜV SÜD Battery Testing GmbH. "At the moment, there are many different systems on the market whose effectiveness and economics cannot be reliably assessed due to a lack of experience.”

TÜV SÜD says it has already certified the first products, adding that its RESS certification enables dependable conclusions on the safety, performance and durability of stationary storage systems.

The certification is based on a comprehensive testing program that takes into account all relevant standards for stationary storage systems and their individual components, including IEC 62619, IEC 60068, IEC 62109-1, IEC 62109-2, VDE-AR N 4105 and IEC 62477-1.

The program includes checks of the mechanical, electrical and software engineering of the storage designs, safety and environmental testing for batteries as well as for security and network conformity testing for inverters. The process also offers analysis of product documentation as well as onsite inspection of serial production at the manufacturer site.

"Of course we check not only individual components but also the reliable interaction of the components in the entire memory system as part of the RESS certification,” says Andreas Faisst of TÜV SÜD Product Service GmbH. "With our certification, we create more transparency in a very exciting and fast-growing market."

The company stresses that the certificate allows manufacturers to demonstrate the safety and performance of their products while also providing a valuable point of reference and guidance for dealers, installers and end-customers.
