Runtime evidence · sourced load
Yes. 49 sourced stations in our current catalog clear the capacity and inverter checks for this load.
01 · Runtime ladder
Nominal capacity × depth of discharge × inverter efficiency ÷ sourced average draw.
| Capacity class | Estimated runtime | Evidence |
|---|---|---|
| 300 Whstep 1 | 229.5 hr | Emergency weather radio load · 2026-07-20 |
| 500 Whstep 2 | 382.5 hr | Emergency weather radio load · 2026-07-20 |
| 1,000 Whstep 3 | 765 hr | Emergency weather radio load · 2026-07-20 |
| 2,000 Whstep 4 | 1,530 hr | Emergency weather radio load · 2026-07-20 |
These are comparison projections, not a promise. Temperature, inverter behavior, cycling, and the individual station's measured delivered capacity can change real runtime.
