The Eos Indensity Core is a self-contained energy storage unit that packs Eos Z3 battery modules and the Eos DawnOS platform into a compact form factor. It combines zinc chemistry, a configurable design and AI-enabled software, and serves as the building block of the Eos Indensity gigawatt-scale energy storage architecture. The weather-ready unit can be moved with a standard forklift and stacked on a steel superstructure to make use of tight footprints and available vertical space. Plug-and-play electrical and communications connections simplify installation and integration, while onboard cooling fans, a built-in BMS and a single string of Eos Z3 modules round out the design.
