I like the "emergency" case. I'd love to be able to just turn this feature on when my power goes out.
If you already have PV, or are planning to get PV panels, the cost to go to an emergency off grid situation for a day or two is not nearly as expensive as buying an electric car: Lead acid batteries, large and heavy, are cheap by comparison to the light, small batteries required for automotive use. I have a couple thousand dollars in sealed glass mat lead acids that are supposed to last ~20 years with absolutely no maintenance other than the charging supplied by panels. In case of grid failure, the batteries kick in, in 1/300th of a second with computer grade sine wave. A gas fired generator would cost more than the battery system upgrade.
My house uses about 17 kWhk, the water pump and septic pump use about another equal, and the electric car uses another similar (YMMV)
one way to get off the grid and live of batteries
GM Turns Used Volt Batteries Into Off-Grid Power Structure - Earth911.com
The ABB Group's off-grid structure uses five former Volt batteries to provide 25 kilowatts of power, or enough energy to power three to five average American homes for two hours.
The world loves to be deceived.
