You may not need as big of a generator as you think.
I have two separate 200A breaker panels with separate feeds from the meter.
There are two larger A/C units, plus a third ductless mini-split for the
shack, and lots of other electrical stuff. (My next door neighbor had
recently installed a 20kW Generac) When I first looked at a whole-house
generator, every company said that I needed at least a 38kW generator, some
even confirmed that with Generac. The cost was north of $35,000, and the
generators were all water-cooled small automobile engines. No way was I
going to afford that, and I wasn't going to mess with car engine generators
either. OF course these electrical contractors were not the brightest
bulbs in general, one even told me that the joule was named after a famous
Then, I found an electrical company that was subcontracting on some other
work here. I told him of my story, he looked at the panels, and told me
that Generac has an ATS that uses smart technology (the Nexus line), which
can shed loads based on current loading. That way I only needed a 20kW,
nat-gas, air-cooled Generac unit. So far, it has worked wonderfully. The
cost was one-fourth of what others were saying. I had planned to implement
"manual load shedding" (me tripping breakers as necessary) to reduce the
load requirements, but the Nexus will do that even if I am not home at the
In an unprecedented resolution, the generator came in on-time and
under-budget. I realize that I WILL pay for that sometime in the future.
So, check out the newer, smarter technologies out there. You may not need
as big a generator.

Well, most people don't prepare at all. Not at all. I basically feel
they deserve to freeze or starve.
They don't even have a dozen AA cells in the freezer or 'fridge.
You have got to wonder.
I have only a 2 kVA Honda Inverter generator. It runs mostly
everything I need except the HVAC. Still, I have had neighbors come
buy to ask to plug in cell phone chargers. I not only allow it but I
give them an outlet strip. I allow as many to plug is as appear. I
have dozens of outlet strips as a result of decommisioning a radio
network, so iI could likely accomidate a hundred chargers. It would
be a real mess on the front porch. I don't recall more than six
plugging into the generator.
I plan to get a 40 kVA generator for the entire house. Of course, my
wife and I need to become employeed, a problem for both of us right
now. However once we have jobs and don't have to worry about the
bills, I will install a 40 kVA generator and put two or three 10
Ampere outlets on it for those living closest to us. Hey, they need
to live with the noise, even though I plan to buy a low noise gen-set.
They can plug in there 'fridge or some other low load. If they want
to plug in something larger, the breaker will trip.
HEY, IT IS FEE. Get over it.
