You have a much more advanced system than ours. But we live in the foothills and have frequent windstorms which knock out our power. Most of the time it comes back on the same day, but occasionally it will be off for a week or more. All of our neighbors have generators. Fortunately, we have natural gas to the house, and I converted our generator to use it years ago.
So, it is still a similar situation for us. When the power goes out we have to limit how many high wattage devices that we use at the same time and we also have to pay attention to which side of the 240v circuit that they are running on. We have metering that allows us to monitor this.
We are so used to the routine that we do not have to think about our usage very much. Typically, if someone turns on a toaster, microwave, or hair dryer that are on a side of the circuit that is already close to the limit... the generator starts to bog down and we turn the offending device off and then go turn off something else before starting it back up again. Occasionally, a breaker will flip which is a little more inconvenient.
Some of our neighbors who have the approximately the same load that we do are using generators twice as large as ours. This means that they can get away with a more asymmetric load than we can, but it also means that their gas usage is typically 50% or more greater than ours during a power outage. This hardly matters during an outage that doesn't last very long, but if you are using a generator for a couple weeks it can add up to quite a bit more consumption.
And don't forget other energy improvements to the house. My solar is good, but probably as important are the insulation we added, replacing my old A/C and gas furnace with a variable speed heat pump, and replacing my old gas water heater with a hybrid water heater. When I post that my energy project will pay for itself in about 10-11 years, I include those costs as well as the extra cost for an EV (vs buying my wife another used ICE crossover since I was about to have to replace her car anyway).
To make solar efficient you have to think like an engineer and strengthen all of the weak links and also pick your battles. For example, where I live when it's cloudy and rainy for multiple days those tend to also be days with moderate temperatures. In other words, even though I have to pull from the grid on those days it's not much because I don't need a lot of power to cool or heat the home when the outdoor temperature is mild. But most of the days it's really hot or really cold (cold for Alabama) tend to be sunny days, which means lots of free power to handle the high power consumption.
Once I realized that I realized that solar would do most of what I need it to do and my budget would be hampered only a little by the Dims' stupid energy policies (the little I have to buy from the grid).
