Default Tesla announces a new battery for home use

It's surprisingly affordable. I'm sure that there will be glitches but it's encouraging to finally see some serious effort to provide a practical battery for home energy use.

The patent is open to everyone to use. This will be a game changer.

I initially thought the peak output was 500W, but it can do 2kw, so I could run my servers off it.

The thing is, I don't see what its doing different from existing products on the market.

Here's a $3,000 5000VA UPS on Amazon (Roughly around 4KW for most loads)

From what I can tell, he's got a lower price point (compared to the enterprise server hardware I linked above), but that alone doesn't seem big enough of a difference to justify the hype going around the product. What did I miss?
