[ausev] Residental Solar Power ROI

[Aaron Choate]

Have those of you with solar arrays who have EVs experimented with using
your traction pack as backup power during grid outages?  One of my strongest
interests in solar + EV is that I can be offsetting the power that my
vehicle is using with what is being generated off of my roof.  Having the
pack available for emergancy power would be very cool.  Just curious if
anybody has been working to hack a solution together.

Cheers,

Aaron Choate
