Batteries on a plan like that, where they’re part of a large virtual battery, do pay for themselves within warranty
Solar batteries never do. To rationally buy a battery one needs to put high value on backup power
The math has been done multiple times. The batteries don’t pay themselves back, and also need to be replaced from time to time.

Sure. But the math depends on electricity tariffs. And those change and therefore, so does the maths. it sounds like tariffs are pretty extreme currently
