Everything below comes from what Sigenergy publishes about the SigenStack: the datasheet, the product page and press releases. Where a figure is not published, the field says so — we do not estimate.
Variants
Energy figures are nominal (beginning of life) as published by the manufacturer. One model, several duration options — the same enclosure with different power ratings.
| Variants | Energy | Power | Duration |
|---|---|---|---|
| 1 stack, 4 modules (48.24 kWh; power = 0.5C nominal rate) | 48.24 kWh | 24.12 kW | 2 h |
| 1 stack, 7 modules (84.42 kWh; power = 0.5C nominal rate) | 84.42 kWh | 42.21 kW | 2 h |
| Max. system: 21 modules / 3 stacks (253 kWh; power = 0.5C nominal rate) | 253 kWh | 126.5 kW | 2 h |

Key facts
- Stackable DC-coupled C&I battery: 12.06 kWh BAT 12.0 modules (105 kg, 314 Ah LFP cells), 4–7 per stack, up to 21 modules / 253 kWh per system
- SigenStack BC battery controller (M2-0.5C, M2-0.5C-BST, M2-1C-BST) with 180 A to/from Sigen C&I Hybrid Inverter; 0.5C nominal, 1C max
- Pack-level fire suppression (aerosol + smoke sensor + exhaust) and active balancing; smart air cooling, IP66, <65 dB
- Cycle life 10,000 quoted from cell manufacturer at 25 °C, 0.5C, to 60% SOH
- Dimensions/weight above are for a 7-module stack incl. base and BC (770×363×2543 mm, 815 kg); RTE, warranty and PCS power depend on paired inverter and are not stated
What Sigenergy does not publish for this model
These fields are empty because no public datasheet or release states them. That is information too: ask for these numbers before you shortlist.
