100 kW–10 MW power block; about 200 kWh–6 MWh per 10/20/40 ft enclosure depending chemistry/density

1 MW to 1 GW+ project scale; 0.5–8 hour common duration, longer-duration chemistries beyond

30 kW–2 MW; 50 kWh–5 MWh; indoor cabinet or outdoor container

100 kW–20 MW; 200 kWh–100 MWh; peak shaving, resilience and microgrid duty

250 kW–100 MW; seconds-to-hours duration; UPS replacement, ride-through or behind-the-meter applications

10 kW–20 MW; 20 kWh–100 MWh; grid-forming/islanding options

Module about 2–30 kWh; rack about 100–500 kWh; systems from tens of kWh to multi-GWh projects; 400–1,500 Vdc common
