The Checks, One by One
| Check | Result | Detail |
|---|---|---|
| Pure sine wave | ✅ pass | Inverter is confirmed pure sine wave, which this appliance requires. |
| Running watts | ✅ pass | 2400W continuous output covers the appliance's 400W running draw, leaving 2000W of headroom. |
| Runtime | ℹ️ info | 2048Wh of battery at a 75% AC-inverter efficiency factor gives roughly 3.8 hours of continuous running at 400W. |

Methodology
Verdict computed from this project's verified entity data using the same gates as its use-case scoring: waveform requirement first (an unconfirmed inverter type fails rather than passing), then continuous watts, then startup surge, then runtime at a 75% AC-inverter efficiency factor. Entity specs verified 2026-09-13; appliance figure from data/use-cases/oxygen-concentrator.json (draw_scenarios_w.home_concentrator_continuous_flow).
