I think(?) the idea is that you would charge the battery at night when energy costs are lower, then discharge during the day when costs are higher. In that case, the brains are providing value that a dumb UPS can't.

If I'm right, the copy on the website seems to assume the reader already knows about the whole "charge at night, discharge during the day" thing. Could use some reframing if the target demo is "the 99.7%"

If that's the case i would be interested to see the savings when you consider loses from batteries vs direct consumption at the time.

I'm not trying to poo poo the product, just some honest analysis of what it can do and the cost or savings.
