Thanks Eric, this is helpful. I agree that the % seems to be more accurate than the miles range. I need at least 180+ miles range as driving son to school back and forth is 160 miles per day, this is one reason I got the Tesla. Luckily we have enough SuC at both ends (home, school) so we can manage. Agree the car is fun to drive (I have been renting Teslas for some time at Hertz)
BTW I don't know if this is the right forum, but does anyone have experience with using a Powerwall to charge the car? We are planning to get a Level 2 charger installed shortly but I am told that it will take 4-5 hours, curious if a Powerwall can speed it up! Thanks, Vijay
Well, it looks like you will be driving enough to get a lot of satisfaction from the fun of driving your Tessie!
No, a Powerwall will not speed up charging because even with a Powerwall you will be using alternating current (AC) to charge the car. There is no way to get direct current out of a Tesla Powerwall for fast DC charging like is done when using a SuC.
So the maximum you can charge your MY at home will be 48 amps which at 240 volts is 11.5 kW.
With both my MXP and M3 RWD, I recover slightly more than 10% of the battery each hour I charge it. This is because the MX charges at 48 amps, and the M3 RWD charges at only 32 amps, so even the smaller battery in the M3 RWD does not recover faster than our MX. However, your MY is capable of charging at 48 amps, so it will probably recover a bit more than 10% in an hour.
If you are not familiar with the installation process of getting a Tesla Wall Connector installed, there are a lot of threads on this web site, with advice for DIY and when using an electrician.
Even if you use an electrician, I think it is good to understand the process as there have been some electricians who whilst licensed and reputable are not familiar with the nuances of installing EV circuits, which relates mostly to them not understanding the continuous load that an EV presents to the circuit, and which must be de-rated by an 80% factor. This applies even to electricians on the Tesla approved list. So it can be helpful to understand such nuances even if you hire an electrician. These threads (but there are many more) have a lot of good information on this subject:
We recently moved to a new house and the Main Panel had plenty of room and a fairly short run to where I wanted to put a Wall Connector. I was initially going to install a level 2 NEMA 14-50 Outlet and use my spare mobile charger, already purchased Homeline 50A GFCI breaker, and Hubbel 9450...

A friend of mine installed two Nema 14-50’s in his garage to charge his Model S and Y. One day he got a message that one had Faulted out. When he went in to the garage there was a smell and smoke but luckily no fire. The system was all crusty and burnt up. It was a scary site. He had the...

Piggy-backing on this thread I found in the Canada section that ran from 2018 -2021: Post your Garage charging setup! Did not see a general or recent thread on garage setup pictures. Minor updates to the Canada thread's guidelines: 1. snap a photo of your charger setup in your garage 2...
