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 Qatar that is Kahramaa. Confirm the grid code, import requirements and any local certification with them, or with us, before you order.
Key Features & Technical Highlights
- A brick that repeats: 5.12 kWh per 44 kg module, sized at 440 x 133 x 540 mm for racks, floor stacks or walls.
- Gentle 0.5C cycling: 50 A continuous charge and discharge, with 100 A available for ten-second peaks.
- 4.1 kWh per cycle: Usable energy at the recommended 80% depth of discharge from the 1P16S LiFePO4 pack.
- Up to 327 kWh together: A stated limit of 64 modules in parallel - 32 without a CAN-Box.
- Breaker-backed BMS: A built-in circuit breaker adds a physical layer over the battery management system.
- Eight-LED reporting: Five SOC LEDs and three status LEDs, alongside CAN2.0 and RS485 communication.
