Anyone reading this and still trying to figure out what to do with L2:
1) To do 48A continuous you need a 60A breaker and enough “room” in your load for it. (Your house only has a certain amount of load.) There are electrical rules about needing 20% higher breaker than the continuous load and next breaker size up is 60.
2) If you talk to electricians to do the work and they mention using “#6 Romex”, you won’t get 48A continuous. (Well, you could but you can also burn down your house.) the wire has to be rated to handle the 60A breaker due to load and heat. If they refuse and tell you it will be fine, find a different electrician.
For some reason it’s pretty pervasive to use less than adequate wire with that #6 Romex. I’ve got no clue why, but you can only run 30-something amps through that wire. Probably because the proper wiring is a little more expensive.
As a different note, I did have a company argue they could use the #6, but the electrical code is quite clear. Scary stuff. But dude was in sales and probably had no idea.
Northern VA here. Wall charger 450. Install 1500. Big house. Long cable run to garage. Tesla website recommended electrician. He was the best. All he does are wall chargers. 60 amp circuit.
Varies greatly depending on how far away and how easily wire can be pulled from your panel.
These numbers are probably about right if your panel is in your garage and close to where you want the wall connector.
Mine was on the other side of the house and through various finished areas. :(
True on all, I was fortunate and ran it 3’ from panel… greater the distance, greater the need of copper and copper ain’t cheap when doing stuff for EV charging.
Depends on your rate plan. I don’t charge over 25-30A usually because our power company charges a demand fee which is “Highest 15-minute interval reached ANYTIME of day. Billed at the single highest interval over the billing cycle”. And it’s $4/kWh during that 15m. 48A is way higher than our A/C and hot tub running at the same time so I keep it low and start charging after 10pm. What do I care if it finishes charging at 1am or 4am?
TLDR: Mobile because it's easier. Wall because it's fast and cool
Honestly, the 240v mobile is pretty sufficient.
I get a bit of a rebate for the wall connector from my power company. (Not enough to justify)
I haven't had it for long, but I could see it being useful in certain situations. Say you were going on a trip after work and have a bit of time to prepare at home. Stuff like that. I'm also an enthusiast with things like this, so I personally do not regret it.
You have the 2024 model, yes? I didn’t mean to assume that it was the rwd but there wasn’t a dual motor emblem in the graphic.
The rwd model uses a new LFP battery that can be charged to 100 every time with no risk of degradation
I’ve been trying to figure this out. I have the 2024 RWD manufactured in Fremont and can’t figure out the battery type. There’s also no “charging tip” on the screen. Is there a way to verify the battery is LFP?

And that's before factoring in the length of the run
Always. Won't do any harm
Anything below 1 C is not a problem. 1 C is about 75 kW on the LR
How much did it cost you?

How long a line? I am in your area and looking to do the same. Can you share the contact info of the company you used?
Same situation in northern Virginia. Please provide electrician contact.
Buri Electric. Emmanuel. Highly recommend.
120ft. 4 gauge wire. He used emt conduit in the garage. Looks fantastic. Buri electric
60-100$ do it yourself. Edit: if you pay someone to do it, it will probably be around 450-600. Just make sure they’re a real electrician

I paid $1100 for an electrician to install mine. They did a great job and it works every time I use it so I’m happy.

Did you install the Tesla Wall Charger or did you opt for something else using the Mobile Charger?
Wall charger. We also have a 240-volt outlet in our garage for the mobile connector
If you could only pick one, would you have stuck with the 240V or go with the Wall Charger? Why?

There’s no need to cap charging at 80% in your car. Just charge it to 100
That contradicts everything I've been told. Do you have any support for this? Thanks!

This isn’t lfp.
Yep OP responded, you can’t see the dual motor badge in the graphic from here so I thought it was rwd
Sadly the RWD doesn’t charge at 48A shown in their pic. 32A max with 7.7 kWh on the wall charger.
Yes, it is the 2024 long range. That makes sense. Sorry I didn't clarify. Pretty interesting tho!

If you can charge at 48A it’s not a RWD.
