LG Chem is part of the Korean electronics group LG Electronics and specialises in the production and marketing of battery storage systems. The manufacturer based in Seoul has a clear focus on compact storage units for stationary and mobile use. Already in the current 3rd generation, the devices of the RESU series in energy density and size are hard to beat. It is therefore no surprise that they are used worldwide with numerous well-known manufacturers such as SMA, Solax, SolarEdge, etc. Thanks to the RESU Plus Box, the power packs can also be put together to form a mixed double of any 48 V units. LG Chem is now also represented in the high-voltage segment with the RESU 7H and 10H.
