How many powerwalls?

True, but that is why there is no answer to how many. Still starts with how much money one wants to put into this stuff. Most have limited funds. Batteries are EXPENSIVE!!!

Our state taxpayer subsidized batteries (and disconnects) are the bees knees. Although I woulda loved to get a 2nd free battery....

Interesting, when I had my system installed the configurable recommended 3 pw. 10.5(custom) kw system, no ev yet(on order) and usage about 10.2 kw.
Curious to see how 1/2 batteries is sufficient for systems larger than mine, I wouldn barely last a summer day on 3 batteries during a blackout.

Irony has it, this will be tested out tomorrow
