Starlink: how much battery you need
Starlink (standard dish) draws about 60 W (40–100 W range), runs 100% of the time and uses 720 Wh per day. Start-up surge: 100 W.
Draws 50–75 W continuously, more in snow-melt mode; the Mini dish uses 25–40 W and is the better outage companion.
Battery needed
| Hours | Wh | Battery (Wh) | Inverter (W) |
|---|---|---|---|
| For 8 hours | 240 | 364 | 66 / 100 |
| For 24 hours | 720 | 1091 | 66 / 100 |
| For 72 hours | 2160 | 3273 | 66 / 100 |

FAQ
How many watts does a Starlink (standard dish) use?
Typically 60 W while running, with a range of 40–100 W depending on model and age. Start-up surge can reach 100 W.
How long will a 1000 Wh power station run a Starlink (standard dish)?
About 11 hours on the clock, allowing for the 100% duty cycle, inverter losses and a 20% reserve.
What size power station do I need for a Starlink (standard dish) overnight (8 h)?
About 364 Wh of battery and an inverter rated at least 66 W continuous with 100 W surge.
Can I run a Starlink (standard dish) on solar during an outage?
You need roughly 480 W of panels in winter to replace a day's use (720 Wh), charging through a station with a big enough MPPT input.
