You get V2H vehicles where if/when your house is disconnected from the grid; you just carry on like normal when the cars plugged in and supplying power into the whole house's mains.
ie: A good inverter changes the DC into AC of the correct voltage AND gives that AC a nice sine wave rather than a cheap 'square' wave AC.

V2G
is the same thing
BUT
you need 3 AC outputs 120 degrees out of phase with each other to make 3 phase power.
THEN
you need to sense when the grid AC's phase 1 say, is at say the very top of it's sine wave and output your AC so that it's exactly the same and thus IN PHASE with the grid.
If it isn't; you get large sparks, electrical fires, chaos and pandemonium!

V2H (with its large battery pack) may be fine for pgfpro.
It all depends on his use vs output and what the local state of affairs/chaos is when it comes to selling power back to the grid.
I have a feeling he will be producing a good bit more power than he can use though, so V2G... or a discreet deal with his neighbours!
