What Size Power Station to Run Starlink?

Starlink is the load that breaks people's sizing intuition, and it does so in the opposite direction to a space heater. A heater is a huge draw for a short time; Starlink is a modest draw that never stops. Both empty a battery; only one of them does it quietly over 24 hours while you are asleep.

The arithmetic

That result is worth sitting with. If you run a standard dish 24 hours a day off-grid, you need to generate well over 2,000Wh daily, which is a serious solar array. If you run it for the evening, you need about 540Wh, which a 1kWh unit and a 200W panel handle comfortably. Nothing else in the sizing changes as much as that one habit.

The sizing bands

Add 15-20% for inverter losses if you power the dish through an AC outlet, which most people do. If your setup can take DC input directly you skip that conversion — but check the voltage and connector requirements for your hardware before assuming it will work, because the DC path is not supported on every generation.

Why this is really a solar question

A continuous load means the battery is a buffer, not a supply. Whatever Starlink uses in 24 hours has to come back into the unit in the same 24 hours, and that puts the solar input ceiling at the centre of the decision — exactly as it does for a refrigerator.

This is where the unit's input ceiling decides the purchase. EcoFlow publishes 1,000W of solar input on the DELTA 3 Plus and the DELTA 2 Max; Anker publishes 600W on the C1000 Gen 2 and 2,400W on the F3800; Jackery publishes 400W on the Explorer 1000 v2. A 400W ceiling cannot be argued up, which rules it out for a continuously-running standard dish. How much solar input do you need has the full derate reasoning, and best portable solar panels for power stations covers the panels themselves.

What else is on the battery?

Starlink is rarely the only load, and it is almost never the biggest. In a van the fridge usually is; at a remote cabin the fridge and the water pump are. Size the whole build rather than the dish: what size power station for van life and best solar generator for off grid living both work through the full load list, and once a 12V fridge at 400-550Wh a day is in the total, a Mini's 720Wh stops looking like the deciding number.

If you want the commercial shortlist rather than the arithmetic, best power station for Starlink ranks the registry for this use case specifically, including the units with the port types and the switchover figures that suit a router you do not want rebooting.

Three practical savings

1. Turn it off. The single biggest lever, by a wide margin. Six hours instead of 24 is a 75% cut.
2. Avoid double conversion. If your hardware supports a DC input your unit can supply, you skip the 15-20% inverter loss. Verify the voltage and connector requirements first.
3. Keep the unit warm in winter. A cold battery delivers fewer usable watt-hours than its rating, and a continuous load finds that out quickly. Power stations in cold weather covers the derate and why charging below freezing is blocked.

What we have not done

We have not metered a Starlink dish, and we do not publish a single wattage figure for one — the bands above exist so the formula is usable, and the number you should put into it is the average power draw published for your own hardware generation. Every power-station figure is the manufacturer's published specification, linked below. How we choose.
