Runtime evidence · sourced load
Starlink draws 75 W while running. 58 stations clear the capacity, inverter, and startup checks at that load.

01 · Runtime ladder
Nominal capacity × depth of discharge × inverter efficiency ÷ sourced average draw.
| Capacity class | Estimated runtime | Evidence |
|---|---|---|
| 300 Whstep 1 | 3.1 hr | Starlink (Standard kit) load · 2026-07-06 |
| 500 Whstep 2 | 5.1 hr | Starlink (Standard kit) load · 2026-07-06 |
| 1,000 Whstep 3 | 10.2 hr | Starlink (Standard kit) load · 2026-07-06 |
| 2,000 Whstep 4 | 20.4 hr | Starlink (Standard kit) 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.
02 · Reading the numbers
Starlink is a rare thing in this catalog: a genuinely continuous load with no startup spike. The Standard kit averages 75–100 W and holds it, because the dish is tracking and the router is on whether or not anyone is using the connection. There is no duty cycle to exploit and no cycling to plan around.
Forgetting that continuous means continuous. At 75 W, a full day is about 1.8 kWh — more daily energy than a refrigerator, from a device most people mentally file next to a laptop. The second surprise is cold weather: the dish draws extra power to melt snow, and that demand arrives exactly when solar input is worst.
The 75 W figure is the low end of Starlink's own published 75–100 W range for the Standard kit, and heavy-use days trend toward the top of it. Other hardware generations differ, and none of these figures include the snow-melt draw.
