V2H - V2G - V2L capability

There are a few vehicles available with Vehicle to Home bi-directional charging capability but it seems like most companies have avoided it till now.
On the face of it, there seems to be fantastic potential for reducing your home power costs by shifting the time when you buy electricity from the grid.

We have solar so in theory could charge during the day, have the car plugged in to run the home during the expensive hi load period (5-11pm) then if needed top up the car battery in the off peak period (11pm-5am). The main stopper is the current cost ($10k approx.) of the wall unit required.

While it is not my driving interest, there is the possibility of feeding back to the grid in peak periods but it seems the grid suppliers are holding back on getting involved. Might help balance grid loads in peak periods.
Has anyone out there successfully embraced these benefits with their V2H capable EV?

I have a generator inlet in my garage so that I can power two (isolated) circuits in a blackout using vehicle-to-load. It's fantastic.

When V2H becomes available on a car that has at least a 150kWh battery and is able to provide a peak discharge rate of at least 8kW and a continuous discharge rate of at least 4kW, I will buy an EV.

150 kWh is a huge amount of energy. How many days of autonomy are you looking for, given that you have the grid available as well?

@Pansell I have a friend with similar thoughts. Wants to drive from Brisbane to Melbourne without stopping. My bladder isn’t that strong.
I have a Tesla Powerball 2 and if I had a second one I’d never draw during peak power. Most EVs today are the equivalent of 4-5 Tesla batteries and cost about the same as 4 Powerwalls, it just that Tesla also throws in a car as a bonus. I note Tesla don’t offer V2L yet. I suppose it would destroy their Powerwall business model.

The idea that you would spec an EV to do a trip like Brisbane to Melbourne non-stop just makes no sense economically or from a resource use perspective. The other 99% of the time that you are using the car, you are lugging a huge battery around that you don't need. It makes much more sense to have EVs with more modest batteries supported by excellent charging infrastructure.

As time goes on, I am finding my old Nissan LEAF with 120 km of range is actually becoming more usable as the charging infrastructure becomes more ubiquitous.

For amusement, I just plotted a trip in A Better Route Planner (ABRP) from Brisbane to Melbourne in my EV. Over that whole distance, ABRP guides me to stop at eight locations for an average of 15 minutes for recharging. Is that dramatically different to the NRMA's own recommendations for 'stop, revive, survive'?
