Agree 100% .. my expectation is Tesla releases a few different batteries. The new leaked batteries are likely just for Semi and Plaid cars. M3/Y will get Lithium iron cells with a million mile duty cycle maybe and a price drop once implemented ... or something like that.
50 amp breaker, 40 amp charging should be fine. I installed 80 amps for my MS, but never use it at 80 amps .. no need. Tesla wall chargers are nice and not expensive ... installed It myself and saved a lot!
My business focuses on Return on Investment (ROI). My recommendation to people is to think like a utility company .. meaning long-term. Your array will generate for 30+ years and there is a good chance that you will be using more electricity in the future because of EVs and the electrification...

I have an 100 amp circuit with an 80 amp breaker for my wall connector. I never use it at full capacity and instead charge at 40 amps. 30 amps would be plenty .. and I drive 50,000 km / yr.
I’d also suggest you look at solar again. You should be able to get an install for $2/watt .. that...
