Runtime evidence · sourced load
Yes. 1 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 | 0.3 hr | Sump pump (1/3 HP) load · 2026-07-06 |
| 500 Whstep 2 | 0.5 hr | Sump pump (1/3 HP) load · 2026-07-06 |
| 1,000 Whstep 3 | 1 hr | Sump pump (1/3 HP) load · 2026-07-06 |
| 2,000 Whstep 4 | 1.9 hr | Sump pump (1/3 HP) load · 2026-07-06 |
These are comparison projections, not a promise. Temperature, inverter behavior, cycling, and the individual station's measured delivered capacity can change real runtime.
