Everything below comes from what Prevalon Energy (Nextpower) publishes about the HD5 AC: 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 |
|---|---|---|---|
| 5 MWh 2h — inverter DC 2.5 MW / AC 2.63 MVA | 5 MWh | 2.5 MW | 2 h |
| 5 MWh 4h — inverter DC 1.25 MW / AC 1.435 MVA | 5 MWh | 1.25 MW | 4 h |
| 5 MWh 8h — inverter DC 0.625 MW | 5 MWh | 625 kW | 8 h |

Key facts
- 20-ft AC block: liquid-cooled LFP (315 Ah) + integrated string PCS (500 kW fault-isolation blocks), 690 Vac 3-phase to a Prevalon MV transformer (12–34.5 kV)
- Self-powered auxiliaries (60 kVA max) — no external 480 V supply; hot-commissioning before grid energisation
- ≥ 426 MWh per acre installed density (incl. inverter-MVT, auxiliaries and augmentation for an assumed 7,300-cycle life)
- Noise 75 dBA (2h) / 68 dBA (4h) at 1 m; seismic IEEE 693 Moderate (High optional)
- Spec sheet states figures are 'design estimates only and are not guaranteed'; DC voltage range and 8h AC rating not given
What Prevalon Energy (Nextpower) 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.
