I'm pretty sure this is the option Tesla will use:
1. Elon specifically mentioned that just a refrigerator, a TV, a few lights, and a couple outlets would be backed up, not the whole house.
2. This is the way most solar inverters are configured, like my Outback unit. You simply move all the above mentioned devices to a subpanel, install a larger breaker in the main panel to feed the Powerwall 2, probably a 40 amp, and then the output of the Powerwall 2 will feed the subpanel.
I haven't heard any mention of a transfer switch, or the ability to feed power back to the grid, but I sure hope so. My Outback has both, but details from Tesla have been very scanty, to say the least. I'm not in any real big hurry, now that I heard they have extended the Federal 30% tax credit for 3 more years.
