I can sort of relate. We just lost power for 5 days. Family of 4 and a garden of 20. Over the years I had decided to equip my house with the most efficient items I could. I own a 5k generator for work that’s also wired for our home. I installed a 100 gallon well expansion tank, (long showers before the well pump turns on) hybrid hot water heater, led everything. We were able to live our lives normally and I was able to keep a dozen Autocobs going with a few fans. We also kept the 2 mini-split heat/ac’s going. Heat for the grow and heat for the house.
When we moved here we had a pretty bad storm that left us without power for 7 days. My 5k gene was topped out by the original 5k watt water heater alone. My plasma tv pulled 498 watts. So the two couldn’t be on together. Now my 2 70” led tv’s and water heater draw 640 watts combined.
