Description
Each configuration is sized for 1–6+ h of discharge, response time starts at 150 ms and availability is above 97%. Reactive power is controlled in four quadrants, with cos φ from 0.9 lagging to 0.9 leading. A Cube module of 2,549 × 2,566 × 2,160–2,257 mm weighs 8,200–8,550 kg, is rated IP55 / NEMA 3R and can be lifted by forklift from all 4 sides or by crane. The cells are sealed lithium-ion, cooling is air or liquid, and the operating range is −30 to +45 °C. Above 1,000 m the ratings are derated. Protection includes fast stop, CO detection, deflagration panels and a lockable disconnect, with aerosol suppression as an option. Components come from pre-qualified Tier 1 suppliers.
How to choose
Start with power in MW at 50 °C and discharge duration in hours, and the number of Cube modules follows from those two figures. For a site above 1,000 m, build the derating into the calculation from the start. If you need a ready container with known energy, Gridstack Pro with 1.4–5.6 MWh and up to 1,500 V DC is simpler, and for heat up to +55 °C with 7.5 / 10 MWh blocks, look at Smartstack.
