yeah it def can be done, I’ve seen people who are on Amber electric do it as they pay the cost if they export solar during the day (see screenshot) the problem is that they’d switch off most days, any time the state isn’t covered in rain clouds or going through a heat wave the price is negative:

So for Amber customers their primary job is fill up battery and don’t export power until night time which is basically a practical implementation of what the article is saying

I was hoping to get this:

The RedEarth V2G charger will enable owners of compatible EVs to power their home with their car’s battery (Vehicle to Home – V2H) and export power back to the grid from it (Vehicle to Grid – V2G).

As for compatibility and according to information on RedEarth’s website, Ambibox has completed official testing with Ford, VW and Polestar, and carried out its own successful testing with electric vehicles such as the Hyundai Ioniq 5, BYD Atto 3, MG4, BMW i4 and Tesla Model Y.

So cool! I’ll fill up my 40kw EV battery during the day (as it sits at home most days) and then export to the grid at night!

The 11kW three-phase charger will retail for $9,990 ex GST — or $10,989 with GST — and that’s before installation.

… what a joke, it needs to be around $2000 tops… for $11000 I may as well just buy a 40kw battery, it’ll be cheaper
