Hover, focus, or tap a layer in the hierarchy. The cutaway and photo overlay light up where that BMS layer is installed.
One container = 1 BAU + 12 BCUs + 48 BMUs keeping watch over 4,992 cells.
Counts: 12 BESS racks x 4 modules x 104 cells. One physical rack = two BESS racks: four modules above the BCUs and four below.
