Key facts
- 20ft DC container, 8 racks of 1P416S with 588Ah cells (PF288-588A) in CTP 3.0 module-free packs of 195.68 kWh; nominal 6,262 kWh, rated 1,565 kW
- Manual states compatibility with centralized or string PCS and 2h/4h scenarios, but only the 1,565 kW rating is published
- IP55 container, IP67 packs; ≤65 dB and C5-H corrosion class claimed for the European version (company news 2026-06)
- The 'M6' name was first used in May 2025 for a 472Ah / 6.28 MWh version; the current product page shows the 588Ah / 6.262 MWh version, for which the company said in June 2026 that scaling to mass production is planned later in 2026
- Certifications: product manual lists only 'GB/UL/IEC/UN/NFPA' without standard numbers; no system RTE, cycle life or warranty published
