ARCTIUM ENERGY COMPANY The Arctium Block Series
Modular DC block platforms, 3.13–12.8 MWh. Each system builds up from a single container to a multi-block array — engineered for grid ancillary services and full-microgrid projects.
ArctiumBlock M
Rated 3.13 MWh (2h) or 3.2 MWh (4h) per block — the basis unit that builds up as 1, 2, 4 or 8 blocks combine side-by-side or back-to-back, reaching 12.5–12.8 MWh at the 4-block standard and scaling further from there. RTE ≥ 96%@4h and >10,000 cycles @ 70% SoH.
| Rated Energy | 3.13 MWh (2h) / 3.2 MWh (4h) — builds to 12.523 / 12.8 MWh at 4-block standard |

| Voltage | 1331.2 Vdc (1123.2–1497.6 V) |
| AC Interface | — (DC, modular blocks) |
| Cooling | Smart liquid cooling, AI thermal-runaway warning (7-day) |
| Ingress Protection | Container IP55 / Pack IP65 / PDU IP55 |
| Dimensions (W×D×H) | 12664 × 2438 × 2896 mm (4-block standard); 1, 2, 4 or 8 blocks configurable |
| Weight | ≤ 24 t per block |
| Operating Range | −30 … +55 °C |
Frequency regulation, renewable smoothing and energy arbitrage for IPPs and utility-connected assets.
Sites needing every layer of resilience — utility, storage, generation and renewables together.
