I am looking for someone that ideally has more than one EV charger installed in their garage. Would love to see someone who has installed a neat nerdy charging setup. Trying to find an installer that would be in my area of Auburn, California.

Ev's that can use more than 48A continuous are not as common these days, so 60A breakers are most of what you will need.I'm kind of curious to see what this thread produces. Everyone's idea of "nerdy" is a little different I'd like to have the cable on a roll-up retractable mechanism on the ceiling.
I wonder if it's better to have each charger on its own ~50A circuit, or put them on shared ~100A circuit so that a single car could charge more quickly. Probably depends more on what your house's supply is because you could also possibly go to two 60A circuits and just max out both chargers
There is firmware available for manual installation that supports Power Sharing on Gen3 Wall Connector now. For some reason, the automatic firmware update doesn't install that version.Ev's that can use more than 48A continuous are not as common these days, so 60A breakers are most of what you will need.
A 100A subpanel, shared between 2-3 chargers sounds about right to me. Unfortunately, I don't have more specific recommendations. Circuit sharing is something the Gen 3 wall charger does, but that version has its own issues in other respects. I'm not even sure that circuit sharing currently works with those chargers, but maybe someone else who has it working can speak to this.
So, you just have normal 240 plugs wired, and the charges just plug into these, so not hard wired?Optimum EV charging depends on a variety of factors including:
- What cars need to be charged (max amps each can take)
- How much capacity is available on the electrical service
- What is the charging window available (Off Peak tariff hours)
- How many miles typically need to be replenished each day
Personally, I have a really boring EV charging setup. Each side wall of the two car garage has a 50A 240V circuit. I have a Leviton 40A EVSE (from 2013) wall mounted over a 6-50 outlet in the left space. My RAV4 EV is parked there. I use the Tesla Mobile Connector (Gen2) plugged into a 14-50 outlet with the Model 3 in the right space. The cord is long enough to reach around the back of the car to the charge port without touching the car.
That is correct. The Mobile Connector uses a NEMA 14-50 and the Leviton uses a NEMA 6-50.So, you just have normal 240 plugs wired, and the charges just plug into these, so not hard wired?
My panel setup for the solar, batteries is in a room below garage. So was thinking to just run one line up into the garage into a subpanel as you suggest. So, 100amp panel and breaker is enough? What size wiring is this? Guess much easier than trying to run 200 amp sub panel? I assume I would need a permit for this?Ev's that can use more than 48A continuous are not as common these days, so 60A breakers are most of what you will need.

So, the only difference here is the connector at the end, all the wiring and breakers are the same. Any reason did not use a 60 amp? Weird different connectors are being used?That is correct. The Mobile Connector uses a NEMA 14-50 and the Leviton uses a NEMA 6-50.
The electrical contractor installed 14-50 outlets by default during construction since I requested 50 amps. The Leviton came with a 6-50 plug, so I just changed the outlet myself when I installed it. I pulled a permit for the EVSE installation since it was wall mounted. The same inspector that did all the construction inspections came to sign off on the EVSE, so he didn't even look at the wiring since it was existing.So, the only difference here is the connector at the end, all the wiring and breakers are the same.

The Tesla Wall Connector comes with the Tesla proprietary connector handle. If you want to use it with a non-Tesla car, you need an adapter to J1772.But, and I am green here, will a Gen 3 ONLY work with a tesla? Since I have SO much extra solar now, wonder is I could find a use EV for a fair price?

Then I could run stuff from this panel. Some say dedicated 60 amp breakers, or is this over kill and should use 50 amp?
Will have to look into the Gen 3 charger since others are using.

With the new panels, I have even more than I can use, even in winterI thought you were banking the excess solar for your winter heating bill?
I thought you did not want an EV?I am looking for someone that ideally has more than one EV charger installed in their garage. Would love to see someone who has installed a neat nerdy charging setup. Trying to find an installer that would be in my area of Auburn, California.
