I'd accept some kind of add-on battery to extend range, that would be cool

Currently I can get around 800 miles with my current 2.7 Ecoboost and the 36 Gallon Tank

great news. ford patented this:

would be nice if it could be used for house backup.

Smart meters allow the Utility company to reduce your power, and even shut it off completely, while still supplying full power to everyone else (or to those that 'matter' more than you do).
no they do not. that is impossible and a BS claim. the smart meter does not have control over individual branch circuits, which would be required for the load shedding youre claiming here.

All the smart can do is shut off the power to the service. that means total blackout. NOT reduction of power usage

* Generac ATS - This is actually my "Main panel" Power comes in here from the meter (And solar since its a line side tap) and the 27kw standby generator, and then goes out to the panel to the left to supply power. If the power goes out, the generator starts itself and the ATS flips input power to it

Then at the bottom on the right is the 30a input for a portable generator
Interesting, so you side-tapped the feed side of the ATS? How are you doing over-current protection?

To accomplish the same thing, I installed a feed-thru panel in front of the ATS and tied the solar into a breaker there.

Correct, my solar is a line-side tap

All of the solar circuits are on breakers in the Enphase Combiner, and there is a 100a fused disconnect with I think 70a fuses in between the combiner and the line side

Ahhh. and you want no lifestyle change. 40kw generator it is.
Easy statement to make. Bet dollars to donuts you need substantially less than 40kw. When I installed our 20KW generator, I got the ability to actually monitor our power consumption. We could get by with 10KW. This is my power consumption yesterday, Texas, it hit 100 degrees outside. My house 50% larger than an "average" home in Texas. It's very dependent upon what you've got in the home. If you've got a gas heated home in the north, you can really get by with a generator that's not very large.

In an ideal world, I would absolutely love a battery system that has peak output at 25kw and has a reasonable amount of storage, but integrates with a small generator. Then the generator could run at optimal load and the battery would flatten out the peaks and dips

Boy would that be cool.

That's available, but it'd require a substantial number of battery packs (like 4-5 Tesla "capacity type"). Hybrid inverters are a thing. It would be pretty expensive.

I don't want more battery though, if I could have a small generator to keep it topped off then a high output low storage battery would be perfect

Enphase are coming out with something soon, but it still has a stupid low max output and the generator input is capped as 12kw, and you can't use the rest of the output of the generator

Solark lets you do something like that, but then no micro inverter support

I have 4 AC units, a pool pump, electric oven, electric dryer, 1kw base load of computer gear, 5hp air compressor and a tesla. I have gas heat however so that's nice. i should be on a 400/320 service but they managed to permit out a 200a panel. but yes for most people a 10kw gen will cover the majority of homes in america on gas heat.

I'm glad I'm not paying your power bill.. :)

when I build a new place it will get 20kw of solar and a bunch of battery. i'll get my ROI on it for sure.
What's the ROI on battery? I get it with 20kw of solar (assuming you can net meter) - but batteries for me might be useful in areas with variable power or useful for power backup... But they add a lot of costs.

ROI on battery can be positive if you have a large time of use differential cost. Here in FL with FPL, my cost is around $0.10 kwh delivered with no time of use metering. other places the cost can vary 2-4 times depending on time of use. Store power in the battery during the day and use the battery power at night to offset the higher cost. example SocalEdison for example TOU-D-5-8PM plan of $0.27 for 8am to 5pm, but $0.55 for 5 pm to 8pm, and then back to $0.27 for 8pm to 8am

price coming down on home storage rapidly. i wont be building for a little bit. so factor that.

also with us driving EV most of the time taking the sun and charging up off it at night is nice. plus backup capability. maybe not so much roi in the battery but def in the solar.
