I'm in Florida, I ordered a 7.2kw system with a single Powerwall. I've been informed by Tesla that they won't be installing a sub panel. The single Powerwall will backup the entire house. This sounds great unless it's (worst case) the middle of summer, it's dark and I'm using the oven and charging the car (50amp circuit) when the lights go out. I'm expecting it to trip almost right away and drain fast if the central AC is running with nothing else running. My home is new(er) built within the last few years and my central AC is efficient yet I'm highly skeptical that a single Powerwall will run the main AC longer than a hour or two if the sun isn't out.
While I'm sure they know what they are doing I almost feel like they (the designers) are doing everything possible to cut costs and corners. I wonder what the impact of this system design will have on the Powerwall long term.
