At the ESS Exhibition 15-17 May 2019 many of the industries energy storage producers attended, but it was clear that many of them are only component integrators. xelectrix Power, on the other hand, showed many interested customers the advantages of dealing with a producer that has over the past 4 years developed an in-house system from the bottom up. The Inverter Technology is game changing and the interfacing between all components mean that our system has been designed to work. From our inverter to our own battery modules, including a highly effective aBMS (active battery management system), our complete package impressed attendees at the exhibition.
