Keep Starlink online
anywhere the grid isn't.

What everyone calls the dish is really a flat panel packing a dense grid of tiny antenna elements that steer their beam electronically. Starlink satellites orbit in low Earth orbit and cross from horizon to horizon in about four minutes, so the terminal is constantly recomputing the phase across every element — microsecond by microsecond — and handing off from one satellite to the next before it sets.

That relentless beam-steering, not your Netflix stream, is why a connected-but-idle Standard kit still pulls about 50 W at the wall, router included, where an old point-once satellite-TV dish draws almost nothing. Load it up — especially with uploads, which are the hungriest thing it does — and it climbs toward 60–80 W. The figure on your wattmeter is really a readout of how hard the array is steering and transmitting at that instant.

Inside, every Starlink terminal runs on DC. But a Standard, Gen 2 or High Performance kit ships with an AC power supply, so an off-grid setup does something quietly wasteful: your battery's DC is inverted up to 120 V AC, purely so the dish's power supply can rectify it straight back down to DC. The inverter loses about 10% on the way up, before the dish has done anything useful; the power supply's loss on the way down is already inside the wall figures above. (Starlink sells a DC-DC power supply for the Standard 4 and 4 X in some markets, and the Performance (Gen 3) kit's supply takes 12–56 V DC; both skip the inverter.)

On top of that, the inverter has to stay awake the entire time the dish is on, and it burns power just being on: BLUETTI rates its AC180 at about 15 W, and Anker gives about 40 W for its big F3800 Plus. At 15–20 W (BLUETTI's figure to our estimate for a mid-size station) that's 360–480 Wh a day burned before the array transmits a single bit; at 40 W it's nearly 1 kWh. The station's eco or auto-off mode won't help, because the dish's continuous load keeps the inverter awake. Starlink's own sleep schedule does: about 25 W for a Gen 3 kit (try it in the calculator). This is the whole argument for the Mini: it takes 12–48 V DC (or a 100 W USB-C PD port) directly and skips both conversions — one owner's six-hour test on an EcoFlow RIVER 2 Pro put the loss at about 7 W from the station's USB-C or 12 V port, against roughly 23 W through the Mini's AC brick. It's also why a pure sine wave inverter isn't optional — the dish's switch-mode supply is a non-linear load that cheap modified-sine units feed badly.

This is the mistake that kills setups. Starlink hardware is genuinely rugged: the Standard Gen 3 and Mini are rated IP67 and −30 °C to 50 °C; the Performance (Gen 3) dish goes to −40 °C/60 °C and IP69K. It's meant to sit on a roof through a storm. A portable power station is the opposite — an indoor appliance. Its LiFePO4 cells will discharge down to roughly −20 °C, but they can only charge between 0 °C and 45 °C, and charging below freezing plates lithium onto the anode and permanently kills capacity. Most stations carry no meaningful ingress rating at all.

So the right architecture is almost always the same: dish outside in the weather, battery sheltered — in the rig, a vented case, a cabin — with only the cable crossing the boundary. And because a dish is a 24/7 load, the station sits in continuous discharge (often while charging from solar at the same time) — a duty cycle that punishes cheap units with always-on fans and marginal cooling. "Can any power station handle Starlink?" On wattage, nearly all can. On environment, no: a unit with no low-temperature charge cutoff, or one sealed in a hot box with nowhere to shed inverter heat, will either damage itself or trip offline.

Cold is where the math turns hostile, because it attacks from three sides at once. The dish draws more — snow melt can push a Standard past 170 W while it heats, in DISHYtech's readings, and the calculator budgets a storm day at +35 W. The battery delivers less usable capacity as the cells chill. And if the pack itself drops below freezing, its BMS will refuse to charge — so the sun can be blazing and your solar does nothing until the battery warms. Only stations with active self-heating dodge that last one; most don't.

The practical answer is to stop sizing for a single night. Size for days of autonomy — the cloudy stretch, not the sunny average — and derate solar hard: nameplate watts assume perfect sun angle and cool panels, so budget around 70% of the sticker and oversize accordingly. A Standard dish's ~2.1 kWh a day from a station's battery becomes 6+ kWh of buffer once you plan for three grey days back to back.
