Someone else may have more info on this, but I think tesla are soon to make their gen 3 and powerwall talk tomeach other to send excess solar to the car. If this occurs it should be a very tidy solutionI work from home (mostly), so weekday driving won't be an issue. It's the occasional longer trips that might be done on back to back days that might be an issue. But really, the issue part of this is whether I may need to schedule a grid draw or perhaps a charge somewhere else. Not the end of the world.
The next thing to work out is whether I should go Zappi 3ph, or use the Tesla Wall Charger + Charge HQ - I think the latter should work fine to soak up the excess solar correctly, but I'm not sure yet. I want to leave the UMC in the car all the time and not use it at home (as in take it in/out all the time). We own our home, so setting up a permanent charging setup is not a big deal (right next to the powerwall ).
You will need a specific adapter for all of your “close to” charging options, and eventually options 1 and 4 will be changed to CCS2 and type 2 as that is the standard supported mr the MTA.I have the following charging options closer to my place.
what additional adapters do I require to charge my upcoming M3?
CCS/SAE 1 Plug 50 kW 1 Station
CHAdeMO
Chargefox Type 2
J-1772
Also, if I go with 32A 3phase industrial-type socket and wire it for single phase + Gen2 Adaptor 32A 5pin - Do i need to buy a Tesla wall connector?
thanks
Yes, you will get approximately 7.4Kw charging with that combination.Just picked up a 2022 model 3 and am now looking at faster than 10a home charging options with the UMC. I have 3 phase power at home.
I've read the whole thread and the very useful pdf guide that someone posted previously by Rudi Cheow. I just want to confirm my understanding of what I need for home 32a charging.

Choose the Bundle that best fits your scenario of where you charge overnight. Check which UMC you have - see this page if unsure then check if you have single phase or 3 phase available power, see here and follow methods 1 or 2.

- 5 pin UMC tail. It runs at 32a because only one of the three pins is wired
Is that correct?
do you mean tesla wall connector?You will need a specific adapter for all of your “close to” charging options, and eventually options 1 and 4 will be changed to CCS2 and type 2 as that is the standard supported mr the MTA.
If you install a 32A 3 phase socket you can use your UMC with appropriate adapter.
If it were me, I would buy a Type 2 to Type 2 cable for the ChargeFox Type 2 and a wall connector as it saves having to remove and repack your UMC every time you charge at home.
Have you had a look at the Home Assistant addon? Might be something to use as a starting point if you want to code your own solution. And if you do, it would be great if you could share it with the community. Optimizing use of unused Solar Power to charge a TeslaOk, that was quite helpful. I think it's going to be the Tesla charger and since I can code as well, perhaps I need to look into how easy it is to access the relevant api(s). Could be a fun little project.
The two most expensive options, and why would you need to remove and repack your UMC every time you charge at homeIf it were me, I would buy a Type 2 to Type 2 cable for the ChargeFox Type 2 and a wall connector as it saves having to remove and repack your UMC every time you charge at home.
All the CCS chargers in Adelaide are CCS 2 and will plug straight into your Teslawhat additional adapters do I require to charge my upcoming M3?
No, a Tesla wall connector will give the same maximium output on single phase as the UMC, and cost you $780Also, if I go with 32A 3phase industrial-type socket and wire it for single phase + Gen2 Adaptor 32A 5pin - Do i need to buy a Tesla wall connector?
If you choose to use the UMC that’s fine, but it’s not designed to mount to a wall, and has no cable management, so to some degree it is at risk of being run over or causing a trip hazard in the garage. the wall connector is not perfect, but it’s a lot better.The two most expensive options, and why would you need to remove and repack your UMC every time you charge at home

Yes.I have 3 phase power at home.

How long is a piece of string?How long does it take to charge via solar alone?
Please explain...Just be wary of charging at very low currents. Both my EVs are only 50% efficient at 6A (single phase) so that can be very wasteful. I charge direct from solar if my excess is >= 10amps and if excess solar <10A, it goes into a battery (at over 95% efficiency) and I pull it out for the EVs at 95% efficiency and around 14-16amps.
