Don't think so - but, with Tesla, who knows.Is it still possible to buy the UMC? I thought It was discontinued and replaced by the single phase MC that comes with the 3?

They said that there isn't the grid stability in Australia
That is total bollocks. Australia has a pretty much bulletproof grid, in most areas. In fact it has been way overbuilt.
I'm just quoting the Tesla technicians that were setting up the Superchargers. They also told me that dealing with AusNet delayed both the Euroa permanent SC location and also Ovens 'by a considerable time'. I guess you'll find out in a few weeksThat is total bollocks. Australia has a pretty much bulletproof grid, in most areas. In fact it has been way overbuilt.
Incidentally, I bumped into the Tesla charging team at the Euroa chargers today, they were updating the final pair of charging stations to CCS. They said that there isn't the grid stability in Australia to get the maximum charge rate from Model 3, so the local maximums will be lower than the US and Europe
Again, just repeating what I was toldI guess Chargefox are using a different national grid that doesn't have stability issues.
According to the Tesla Oz website atSingle phase is the only available hence the desire to look elsewhere...
According to the Tesla Oz website at
https://www.tesla.com/sites/default.../0320_MS_Accessories_Digital_Brochure_AU_.pdf
the S/X 3 phase UMC is still available.
Actually these days even new S and X owners get a gen 2 UMC (single phase, 32A max).I don't know that there is such a thing; there is one for the S/X but the UMC for the three is different.
In order for Superchargers to achieve the maximum 150kW output, they have to have the grid voltage exactly correct. At many Supercharger locations in the USA, they have installed buck-boost transformers in front of each Supercharger cabinet so that they can fine tune the voltage based on the utility transformer and local grid voltage. If the Australian grid has looser tolerances on the time varying grid distribution voltage, then it will be impossible for Tesla to use the same technique to get the ideal voltage to the Superchargers. In any case, I think it should be possible for them to maintain the prior 120kW max that the V2 system used to be limited to.I guess Chargefox are using a different national grid that doesn't have stability issues.
But there seems to be plenty of confirmation that the Standard Range Plus which I'm getting is limited by a 7.7kW onboard charger:

What is the fastest model 3 charge rate other than Supercharger
Practically speaking, the kW limit is the same at the same SOC regardless of charging method. However, since AC charging is limited to 11kW, you have to get to very high SOC for the battery taper to be seen at that low level. I'm pretty sure it's more than 95% on a Model 3 LR, maybe slightly less on a SR+. Probably still more than 90% on all Tesla cars. Even the 41kWh Tesla pack on my RAV4 EV requires more than 90% to drop below 9kWAssuming this is true for the SR+, I wonder what the real world impact to charging times would be... I thought the claimed max charge rates always taper off after the battery capacity hits 60-70%. Does that only apply for the DC fast charging or also to AC charging via the inverter?
This site seems to sell it (cheaper than the Juice Booster too).Actually these days even new S and X owners get a gen 2 UMC (single phase, 32A max).
The days of the gen 1 UMC provided for free are gone.
