it's not bottom of the barrel.

You can build a 16kWh lifepo4 for ~1800$: https://www.mobile-solarpower.com/server-rack-lifepo4.html

That gives you some experience so you'll be able to maintain it as well if any cell goes bad.

Look I DIY'd my battery too. Thats not comparable to buying high end solution.

I'm curious what you mean by high end solution and how that's different.

In my mind it's similar to premade computers vs build your own. Tesla would be something like Lenovo/dell here.

They would just grab the same cells or cheaper and some other off the shelf components and sell them to you at massive markup.

And you get situations like Battleborn where they couldnt even do the connections right and would start a fire by default...

Will build my own as well this summer so really curious whats the best way to do this

I also have built my own offgrid sytems, but sodium is here now, and lithium is not competitive in any metric that counts in a static instalation especialy cost per kw/hr, and will very likely get insured to death as it will never be as safe. My next system upgrade will be aimed at home power/heat/hot water, shop, and car charging.Possibly with the car charging bieng a discreet system that works at a higher voltage and is all DC.
