Runtime evidence · sourced load
Yes. 42 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 | 18.9 hr | Medical refrigerator (76L biomedical) load · 2026-07-20 |
| 500 Whstep 2 | 31.5 hr | Medical refrigerator (76L biomedical) load · 2026-07-20 |
| 1,000 Whstep 3 | 62.9 hr | Medical refrigerator (76L biomedical) load · 2026-07-20 |
| 2,000 Whstep 4 | 125.8 hr | Medical refrigerator (76L biomedical) 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.

Main compromise
10,200 W below the highest output reserve across 42 eligible models
Balanced reserve
Why it fits
$359 current tracked price
Main compromise
$160 above the lowest current tracked price (36 of 42 eligible models have this sourced value)
Amazon offer checked 2026-07-25
Extended reserve
Why it fits
107.4 projected runtime hours
Main compromise
751.6 hours less projected runtime than the longest-running eligible model across 42 eligible models
