Well no I can't as I won't get my Model 3 until March-April.You can try this out for yourself, go to a 22kW public AC charger (if one is nearby) and you will only get 11kW and the app will show 16A.
And a link the the American version shows where the confusion comes from,
|Model||Onboard Charger||Recommended circuit breaker for Wall Connector installation|
Model 3 Performance
Model 3 Long Range
|60 amp circuit breaker|
|Model 3 Rear-Wheel Drive||7.7 kW|
|40 amp circuit breaker|
|Your Tesla||Onboard Charger Rate (kW)*||Typical Added Range|
|Model 3||11||75 km/h|
|Model S / Model X||16.5||90-80 km/h|
|Model S before May 2016||11 or 22|

I discovered something interesting the other day. It appears that the APIs that set charge rate actually allow less than 5A to be set. Using ChargeHQ, I was able to set a charge as low as 1A, which would be around 720W! I actually have my second wall-mounted EVSE (a Jetcharge unit) setup for single phase because of the reason that you mentioned, but it was possibly unnecessary.AFAIK all Australian Model 3 on board chargers are still 11KW. On three phase it will use one of the three 16A chargers modules on each phase, i.e. three off those in parallel. On single phase it will use two of the three 16A charger modules in series to give a total of 32A and around 7KW.
The only benefit in requesting the gen 3 charger to be installed on a single phase is that you can charge at a lower rate. If installed as 3 phase the minimum rate is 5A on each of the three phases or around 3.7KW. If installed as single phase it is 5A on the one phase or about 1.2KW. The only benefit I can see for this is if you are trying to track solar usage on a smaller system or deep into winter.
Costs the same to run the cable and only a small amount extra to terminate. Cable cost is obviously higher, but 6mm orange circular 5 core is not exactly super expensive unless you are making a really long run (I actually used 10mm but I am known to overengineer things).Good point. i thought maybe it would be much more expensive but maybe not
For charging at home, 11kW is pretty fast - that means 20-80% in 3 Hours and 16 minutes.. (for a RWD). Check out Electric car charging cost and time calculator
Definitely nice to have, but probably not necessary for most people. That being said, charging your car on 3 phase is nicer for load distribution for your houses power supply. Having a 3 phase supply and only loading up one phase can cause some problems, depending on your house wiring.
You can charge to 100% everyday and is recommended to charge to 100% at least once a week. This is to keep the Battery Management System happy and so it doesn't get too lost. The LFP chemistry has a really flat charge/discharge voltage profile.Thank you. Pretty happy with that. We have good solar so will charge it between 10am and 2pm when we work from home and it will basically use solar (for the most part) and charge to 100%, without taking too much from the grid.
On the days that we work (get home 6pm) is it recommended to charge to 100% still (for RWD)...which wouldn't use solar as it would be night time and I don't have battery setup at home. Or could I wait a day or two when I'm working from home again or the weekend? I think I read RWD should be charged to 100% every day?

For your use case my suggestion would be to charge to 100% on work from home days to best maximise the solar usage.
Tesla is also possibly being a little too cautious here as they had some issues early on with LFP BMS getting confused as to when the battery was empty. Technically charging to 100% on LFP has a battery life cost associated with it, it is just vastly less of an issue than with NMC and some other lithium chemistries. And they have made the decision that 100% charges are better trade off than losing track of where the bottom of the pack is. Being told you have 20% battery left only for that to suddenly drop to 5% or less is not a good user experience.
I have 15 kW solar and 3 phase power. I appreciate the ability to charge at 11 kW. I don't use it that much, as I tend to charge during the day at a lower rate to avoid using the grid. However, when plans change and I need a quick charge then it's useful.
