Any chance this will be under $2000 in the future?

Likely, be a while though, the 280ah 12v I bought a year ago dropped 20 % in the last couple months during sales.

Possibly, if you want the best $/Wh the 12V 280Ah category is the best.

However expect all of these to be hit hard with the tariffs

Yeah tariff is what I'm concerned about. Should I buy it now when I don't need it yet or get it while it's cheaper before tariff hit

Tariff, plus who knows what will happen to the 30% tax incentive (depends on tax situation and how you use the battery)

Would it be better to buy seperate rack batteries for easy replacement then something like this one piece?

You are right. I already expand my solar system because of fear of tariff and concern of 30% tax credit going away

These supply DC power so you'd need an inverter to turn it into AC. Likewise it would turn AC power into DC to charge it.

Then you might need a transfer switch of sorts so that you could connect this to the electric panel.

Some of this is wrong but it's sure to get someone else more knowledgeable to chime in.

What grade cells are these? Are they UL listed yet?

Depends if your inverter supports 48v or not. These are not UL approved if that matters to you.
