Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in the UAE that rests with the local authorities (DEWA, ADDC, SEWA). Confirm the grid code, import requirements and any local certification with them, or with us, before you order.
Key Features & Technical Highlights
- 4,340 kWh in one footprint: 314 Ah LiFePO4 cells in 1P48S strings at 768 V nominal, inside a 6,058 x 2,896 x 2,438 mm container.
- Liquid-cooled stability: Liquid cooling supports operation from -30 to 55 degrees Celsius and currents up to 3,150 A below 0.5P.
- 3+3 fire protection: Aerosol and water suppression combined in a 3+3 fire-protection system.
- Watchful electrics: AC leakage detection, DC insulation monitoring and a high-voltage interlock guard the plant.
- Coast-and-cold ready: An IP55 enclosure with anti-corrosion above C4, storage to -30 degrees Celsius and humidity to 95% non-condensing.
- Four control interfaces: CAN, RS485, TCP and DIDO tie the container into plant-level supervision, under a stated 10-year warranty.
