Starlink power solutions

Sizing power for a dish that never really sleeps

Starlink is not a phone. It draws power continuously, and it draws more of it when it is cold, when the heaters come on, and when it is working hardest to hold a link. That is what makes it an awkward load off-grid: it is not the peak that catches you out, it is the hours.

Work backwards from the hours you need, not from the battery you happen to own. A site that only needs the dish during the day is a completely different problem from one that has to hold a link overnight, and the second one is a much bigger battery.

There are three usual answers. A 12V setup if you already have a leisure battery and want the dish to be part of the vehicle or cabin system. A portable power station if you want one box you can also use for something else and recharge from a wall or a panel. A dedicated battery with a charge controller if the site is permanent and unattended.

The failure that surprises people is dusk. As the panel output falls and the draw stays flat, voltage sags and the dish drops out — then comes back once the sun is fully gone and the load settles. If your link dies at the same time each evening, this is why. The off-grid power guide walks through sizing it properly.
