I am more concerned about extended rolling blackouts. Based on the direction our economy and this current administration is heading (quickly) I truly believe that is the biggest risk we face in the near termDo you really need a whole-house unit? I have a dual fuel 8500-watt unit that I haven't even started yet in 3+ years. My power has never been out for more than a few hours. I got it just to run the fridge so the food won't spoil. Everything else I can live without for a short time. I have plenty of stoves and BBQ's to cook with and a battery "generator" that will run my CPAP for a few days. If your power goes out that much it might be worthwhile, but if it only goes out for a few minutes to a few hours why spend that kind of money?
