From the specs

CPAP users: follow your doctor’s and the device maker’s advice on backup power.

Motors and solar

3,000 W surge, per ALLPOWERS. Some fridges need two to three times their running power to start (Anker), some compressors two to four times (BLUETTI); check yours.

Solar: up to 650 W, about 2.4 sun hours to full by our math.
