Good grief. How many tons is your AC?
Living a normal day, using all the appliances and lighting and two heat pumps, my running load is 18,330 and the surge/starting watts is 26,000... which is a not gonna happen sort of thing. I cant imagine turning on every electrical device, light and appliance at the same time during a storm or other outage. My AC is 3 tons. A 3 BR home. All electric. No gas appliances.
The one thing a lot of people don't figure in is the sump pump. 900-1000 watts. And if it's raining it may be running constantly.
