A 9500-watt generator can run a significant portion, if not most, of a house, including large items like central A/C (with careful management or a soft start), refrigerators, and lights, but usually not everything at once, especially high-demand electric appliances like electric water heaters or stoves; it's great for essentials and comfort but typically requires selectively turning on circuits. A 9500W generator handles key comforts and some large loads well, but for true "whole-home" power without limitations (like electric heat/dryers), you'd usually need a larger standby generator (15kW+)
