Key facts
- Previous-generation 20ft DC container on 280 Ah cells (LFP280-1P48S modules), 10P384S, nominal 3,440.6 kWh at 0.5P, RTE ≥94%
- 1,228.8 V nominal, 960–1,401.6 V operating; container weight <34,000 kg; IP55; -30…50 °C; altitude ≤3,000 m; ≥101 Wh/kg / ≥80 Wh/L
- Datasheet V4.5_US (May 2024) still hosted on hithium.com but the model is no longer listed on the product page — treated as legacy
- A 3.686 MWh sibling (US/EU datasheets Oct 2023) is no longer hosted
