To build back better
You must first destroy ...
Stage I - gutting the old as it didn't have enough room for the new.
Had 5kWs of solar in 6 sets of 4 - plans are to end up with 10kWs in either 12 sets of 4 or try 10 sets of 5.
Had 30kWhs of batteries (20+10) - adding 43kWhs in a new set.
Had single 80Amp solar controller with a spare - adding the second to be able to charge 'offline' battery sets.
6000 watt inverter will remain the same - but will be able to switch better between battery sets.
(thought about changing/upgrading, but even the added solar/batteries doesn't give me enough storage to want to try running the main A/C - summer months we can average +70kWhs a day and we might be lucky to get 40-45kWhs a day from the solar panels.)
Good thing I have the mains so I don't have to rush things - or maybe not having to rush is a bad thing as slow as I am ...

You mention not having sufficient power generation to run your house's air conditioning unit if the mains power is lost, but have you thought about getting a window or portable AC unit to use in one room if the main power is out for an extended period?
It would not be as energy intensive as trying to power the house AC, and many household units don't require more than standard 15 amp wiring in most homes, and some units can double as a heater as well.

The main difference between ev batteries and your setup is mainly C rating on the battery packs and the need for active cooling/heating. Lithium battery packs tend to be termermental with the operational temperature. You also have to take into consideration that those packs are built for optimal weight and charging more then anything else. As a drone pilot rc AV user some of the types of packs I deal with would scare most people, when you have to consider the batteries are unstable on full charge, and unstable if under charged as well.
If you look at the testla wall ... or whatever the house unit for their solar cell powerbank, they use basically the same type of unit as their ev's.

Unlike EVs I don't have to worry as much about already warm/hot batteries getting hit by 'sudden' high rates of charge/discharge (0 to 60 in a few seconds and hitting those regenerative brakes - which I think has caused a few of those EV fires.)
Big ones aren't in the loop yet, but I've never seen the small ones even get 'warm'. Part of that is because I'm never charging/discharging them anywhere near their limits.

Wait a few years. sodium batteries are going to replace lithium-iron-phosphate. https://www.youtube.com/watch?v=s6zcI1GrkK4
Skipped through bits of his video ... when he claimed the lithium batteries lose 40% of their capacity after just 250 cycles I had to wonder what else he has no clues about. (having had my system up a couple years now I know my batteries haven't dropped that much as yet!)
The older 12.8V 100AH batteries I got claimed over 3000 cycles and they'd still have at least 80% of their capacity, while these newer 12.8V 280AH ones claim 6000 cycles. (and the newer ECO-WORTHY mini 12.8/100AH are now claiming up to 15000 cycles?)
Like many things, we'll have to wait and see if this turns into something, or if there was a very good reason they didn't try sodium batteries first.

Not to be confrontational, but he was comparing data from material data sheets for the same size 'cells'. from a quick search, he's correct. that was one of the downsides of the plain lithium-ion chemistry compared to nickel-metal one. He was also comparing the voltage curves from the data sheets and testing them.
