Ok, thanks for your reply. I did not give much more detail. But here it is. Power failures are not vary common around here. So I am not looking into spending gobs of money in preparation. Because of that, I am viewing the backup power as a temporary measure, not live like we normally would. So this is what I like to lease power, lights, refrigerator and 2 freezers, few electronics like phones, and internet if we have it, well pump. I have a gas insert for a fire place, so that can serve as backup heat, gas cooktop and gas dryer. I have a hybrid water heater, so if I were to let the heat pump portion run only, it wouldn't be near as big of a load, but we could improvise without it. Now, I did buy a Ford F-150 PowerBoost that I would use too, but lets face it, primary, I bought it to have a set of wheels, not as a backup power source. The other thing is I figured 240 volt, 30 amps maxes out at 7200 watts, so I don't see need to buy a generator over 8000 watts. Being my 5500 watt, only has a 240 volt, 20 Amp, this only allots me 4800 watts. I also do not see a need to have an inverter generator, do to their cost.
