I went through a similar exercise for my house, but my goals were different. I want some things to keep chugging during a power outage or brownout. I wanted some lights (not all of them) to keep working during a power outage. I didn't seek to totally power the house, but to independently power (and self-contain) a few subsystems to eliminate wires and some panel circuits. (low-power IT gear, outdoor LED floodlights, air-exchange vents, attic vents) I also didn't seek to sell power back or store much of a reserve. Apparently, this is an unusual approach.
Recalling that rescue workers dealing with Prius might not know if a vehicle is de-energized, one of the thoughts that went through my mind is that an electrician or fireman might think that by cutting off power at the breaker, they can assume the entire house and all subsystems are de-energized. I wonder if their procedures involve checking for alternate sources of power such as checking for solar panels and uninterruptible power supplies. A Prius or Tesla is a distinct shape that can serve as a warning. My house isn't distinctive. Fortunately, a power outage happened and I had to run around the house silencing UPS alarms. Problem solved.
