Description
Each 20 ft container holds 5,644 kWh nominal in a 2.896 × 6.058 × 2.438 m body, with liquid cooling, IP55 protection and a weight of about 45 t. The 4,600 kVA inverter at 690 V takes 1,003–1,500 V DC, reaches up to 99.2% efficiency and supports grid-forming operation. Maximum AC current is 3.85 kA, and the power factor is adjustable from 0 inductive through 1 to 0 capacitive. Self-discharge stays at or below 3.5% per month with the DC side disconnected. The battery part complies with IEC 62619, IEC 62933-5-2, UL 1973, UL 9540 and UL 9540A, as well as NFPA 855, IEC 63056 and NFPA 69. Operating temperatures run from −25 to +45 °C, with C5 corrosion resistance.
How to choose
At the same 4,600 kVA, an i4 block stores 10.378 MWh against 7,250 kWh for scalecube i3, so it discharges longer at rated power. If the grid voltage is above 33 kV, scalecube i3 with its range up to 36 kV is the one to take. The system grows in steps from 11.28 MWh / 4.6 MVA, and one BESU with its service zone occupies 18.6 × 16.2 m (300.3 m²).
