Key facts
- 20 ft AC block: 6,904 kWh LFP plus 4 x 450 kVA liquid-cooled SiC string PCS in one container (datasheet ST6900UX-4H, marked 'Preliminary')
- Press release (June 2025) cites 684 Ah stacked cells, 448 Wh/L, PCS max efficiency 99.3%, system RTE 93.5%; MEA release (Aug 2025) mentions 684 Ah and 661 Ah cell options and '92% overall system conversion efficiency'
- Platform announced in 10ft Flex (3.45 MWh), 20ft Class (6.9 MWh) and 30ft Plus (12.5 MWh) versions; only the 20ft Class has published datasheets
- US SKU ST7140UX-4H-US: 7,144 kWh, 60 Hz, NEMA Type 3S, 2,000 m (3,000 m optional), UL 9540 / UL 1973 / NFPA 855
- AU listing ST6680UX-2H exists (690 V, IP55, C4) but no datasheet or capacity/power figures are published
- Cell supplier, cell configuration, warranty and calendar life are not disclosed
