I don't think so, pretty sure the three-phase HPWC isn't available here yet. I'm pretty sure SteveWest has a third-party charger operating at 3 phase/32 amp on 240V in NZ though.
there are 3 phase type 2 evse installed in Perth, Brisbane, Melbourne and Canberra. (many are ex betterplace.)
Yep, I think the OP was talking specifically about Tesla HPWC units though. I'd be interested to hear if anyone gets their Model S charging from a Better Place unit though!
Has anyone received/installed one of these in Australia please?
Thank you,

yes but steve wests isn't a tesla HPWC tesla don't have any 3phase HPWC yet.
I have dual chargers and have asked that Tesla replace my temporary wall connector with a 3 phase when available.
No firm dates for When the 3 phase wall connector will arrive but I get the impression 2nd quarter 2015.
My understanding bis tha t we will have our units swapped once 3 phase becomes available. That is, if you bought dual chargers. In the alternative they will supply single phase 80 amp, your choice!

After the FIT expires end of 2016, the subarray on phase 1 becomes net metered. I will then move the single phase ESVE to that phase to supply the car charging and a few some other daytime applications. The rest of the house stays on the second phase with the battery storage. The third phase is now just winter heating. So about half the PV will end up dedicated to house with storage and half to EVs, which have their own storage. The third phase will be for winter heating, which is balanced by excess solar sales to the grid during warmer months.
I am sticking with the single phase ESVE.
Effectively it incurs an upgrade cost of $3k, an extra inverter/charger cost ($20K -$7K = $14K) and extra solar inverter installation costs for spreading the array over three phases. This substantially increases the cost of the system. Hence the need for a workaround. A single phase PV installation of 7 kWp should be technically sufficient for most homes for house and car. That would have been very simple, but if that becomes possible, then the single phase ESVE is used for the car.
If you are installing a new system then the best option is to use micro inverters. These have dropped dramatically in price and have the added benefit of isolating each panel from shading issues. Effectively each panel gets its own inverter, so splitting the installation across phases wouldn't be much of an issue. If I were installing my system today (4kW of panels with a 3.3kW inverter), I'd go for micro inverters. In winter time I have a tree that shades some of the panels and that dramatically reduces output - the whole string suffers. With micro inverters only the shaded panels would drop.
Totally agree! One shaded panel "eats" about two panels in the sun, so if just 1/3 of all the panels are shaded, you get zero nil nada out.
Not quite right -- the current for a solar array in series is limited by the current for the highest performing panel (to an approximation -- the MPPT/Inverter will drop the current back to the right level to get the maximum power possible out of the array if it's doing its job correctly).
Moving to micro-inverters means you are minimising the number of cells in series, and therefore the effect that shading will have. More inverters means that your cells are spread between more trackers. Micro-inverters are a good plan, and have been getting more traction these days. Not to mention that you can have very short DC runs which eases the installation.
