The energy storage RESU6.4EX from LG Chem scores as an innovation with high quality, design and ecology. Caused by the technology inside the device, the energy storage is very compact and light and needs only little space. That way, it is also suitable for installation in smaller rooms, areas which are difficult to access or for retrofitting of existing photo voltaic systems. The high quality is guaranteed by the manufacturing with robust metal and nickel-manganese-cobalt chemistry (NMC), which is used in the automotive sector. The RESU6.4EX covers ecological aspects not only by its maximum capability of utilization: The production process makes use of materials which fulfill high ecological and recycling standards. Last but not least, there is the design of the device: the minimalistic metal optics follows latest trends.
