Doesn't have to be amp-hour. Can be 30k houses for 20 minutes which is easy to understand.

I presume that the quoted 30k house represents the power at max discharge rate (for max PR value) so can't hold for too long.

Looking at it that way suggests a worse case scenario with those 30,000 homes finding themselves collectively "off-grid".

But that's not what it's designed to do and it would be misleading to hold it to that standard.

It's designed as a supplement. If we knew it's capacity, we could use an average length of time for a brown-out & the amount of amps required to make up the difference to figure out how useful it'll be.

In that case, the spec should be 15% of the power of 30K homes for a period of 4 hours, or something like that.

This however wouldn't be as impressive as 30k homes with no time limit as Tesla's PR suggests.

My guess is that '30K homes' represents the max possible discharge rate so can't be for too long, a fraction of an hour at most, may provide enough time to start the actual auxiliary generators.
