Motors and solar
BLUETTI lists no surge rating: only a 7,680 W Power Lifting mode for resistive loads. Some fridges need two to three times their running power to start (Anker); its 3,840 W continuous output covers a typical fridge start (about 900 W), but check bigger motors like pumps and AC units. Own draw: about 20 W (manual), included in every runtime here.
Solar: up to 2,400 W, about 1.5 sun hours to full by our math.
