What will an Anker SOLIX C300 run? (EU 230 V)

A “300 W” power station is two numbers wearing one label. Watts are the ceiling on what you can switch on at once; watt-hours are how much energy is in the battery. The Anker SOLIX C300 holds 300 W and stores 288 Wh on the nameplate — and those two facts answer two different questions.

This page answers the first one. Anker SOLIX publishes no depth of discharge or inverter efficiency for this model, so there is no defensible usable-capacity figure, and this page will not turn the nameplate into hours.

No usable-capacity figure for this model

The brand publishes a nameplate watt-hour number and nothing about depth of discharge or inverter efficiency. Dividing the nameplate by a load would be wrong by 20–35%, so this page shows the nameplate for what it is and refuses to turn it into hours.

What Anker SOLIX C300 runs

Every row is a live calculation against this machine's continuous output, surge ceiling and inverter waveform — running watts, start-up inrush and duty cycle on the appliance side. Of 30 appliance profiles, 10 run, 3 are a tight fit and 17 are out of reach. The percentage is the load as a share of continuous output; anything past 82% drops out of the green.

Solar panels this machine can legally take

The binding constraint is voltage, not watts: open-circuit voltage RISES as it gets colder, and an array that is fine at noon can be over the MPPT ceiling at dawn. Each row is the engine's largest legal array for this station, with Voc corrected to -10 °C ambient . Only panels whose datasheet publishes a voltage temperature coefficient are evaluated — the others cannot be corrected, and an under-corrected array is what destroys an MPPT input.

Every field we hold on this machine

Each figure carries the tier it came from and the date it was checked. A blank is never left blank: a field the manufacturer does not publish says so, and a field two manufacturer sources disagree about says that instead of picking one.

Questions people ask about this machine

Will an Anker SOLIX C300 run a full-size refrigerator?
Yes. Against the EU 230 V record, the full-size refrigerator draws 55 W running · 286 W at start-up — 18% of this machine's continuous output. That verdict is a calculation from running watts, start-up surge and inverter waveform, not a lookup, and the full working is one click away in the table above.
Why can't an Anker SOLIX C300 run an electric space heater (1500 W)?
On the EU 230 V record the binding constraint is the continuous output. The electric space heater (1500 W) needs 1,500 W running · 1,500 W at start-up, and at 500% of continuous output there is no headroom to give. No accessory fixes this one — it takes a machine with a bigger inverter.
How long will an Anker SOLIX C300 run my appliances?
We will not put a number on it, and that is deliberate. A runtime needs a usable-capacity figure, and Anker SOLIX publishes no depth of discharge or inverter efficiency for this model — only a nameplate watt-hour rating. Dividing that nameplate by your load produces a confident-looking figure that is typically 20–35% too high. What this page gives you instead is every load's energy rate in watt-hours per hour, which needs no battery figure at all and is the number you actually size against.
Can you take an Anker SOLIX C300 on a plane?
No. At 288 Wh it is far above the 160 Wh ceiling that airlines apply to lithium batteries in the cabin, and lithium batteries of this size are not accepted in checked baggage either. The 100 Wh / 160 Wh thresholds come from the IATA dangerous-goods rules that carriers implement; check your airline before travelling, because the approval step above 100 Wh is theirs to give.
