My new EVSE setup. The Tesla Universal Wall Connector is fantastic device.

[HOTAS]

13 years ago, when I installed my first EVSE, I went with a level 2 Schneider Electric EVLink, good for 30 amps/7.2 kWh.
It served me well for the 3.6 kWh PHEV’s I progressed through, and held its own charging my Tesla MY, at 7.2 kWh, with a NACS adaptor.
Early last year I gave into the desire for a full 48Amps/11.5 kWh to take full advantage of the Tesla’s charge rate capability.
This time I went with the Tesla Gen3 Wall Connector. Beautiful piece, and works like a charm.
Last fall I of course got my beautiful F150 Lightning. Been charging both EV’s with the single Wall Connector, and now a J1772 adaptor for the Lightning. It all worked well, but was a slight coordination PITA.

I’d been wanting to do a second EVSE install, but that would typically require an additional circuit with associated breaker, wiring and drywall surgery or conduit runs back to the panel.
Also a PITA.

Well, not anymore …
Tesla recently introduced their new Universal Wall Connector. It’s pretty awesome. It has a J1772 adaptor built into the housing, that allows you to easily alternate between NACS and J1772. Nice.
But what really makes it special is a new design that allow more than one Wall Connector to literally daisy-chain off the next, and PowerShare the load.
This means a super easy install of multiple EVSE’s on a single existing circuit, load sharing coordination between the two via internal WiFi.
24 inches of wiring is all that’s required.
It also allows DC direct back feeding to the house, with the proper vehicle and home integration equipment.
Very nice design and versatile.

Nice choice! Do you have to run a second "Tesla" charger to power share?

Yes, they “talk“ to each other.
Since I’m only connecting 2, the new universal wall connector will be the leader and my Gen3 wall connector will be the follower. I’ll have to swap the new one into the original one‘s spot and then move the original gen3 over as the daisy chain connection.
Basically, the new universal wall connector has power inputs and outputs. The original just had inputs.
The Tesla gen3 wall connector has always been able to power share, with other gen3, to protect a panel load.
Now the universal one can power share via a single circuit and protect circuit load. If both are charging they split the available load and as one ramps down the other ramps up. Either can charge at full load if the other is not charging. And any individual one can be limited to as little as 6 amps. max.
A total of six can be connected together.

Congrats on your install.

There are other options out there for multiple evse setups too.

Be sure to check local code before doing any installs.

I went the same route after my wife bought her Lightning last year to go along with my Model 3. I also recommend the Tesla Universal Wall Connector to anyone who purchases an EV with a CCS plug so that any future EV they buy with an NACS port will be able to use the same wall charger. For what it’s worth, multiple Tesla Wall Chargers can be run off their own circuits and still limit their power draw via programming when installed. This helped us since how we park in the garage puts the charging ports in very different locations.

When only one is charging i only get about 10.6 kw, not the 11.

Could be a low voltage situation. How are you measuring the 10.6kW?

That’s what the ford app says

I thought they were supposed to have their own home runs with their own breakers. Don’t they just communicate over WiFi to evenly split the load preventing an overload of the panel main breaker? Or is daisy chaining a new feature with the universal charger? I haven’t seen these yet.

Only one 60 amp breaker from main panel but then splits into 2 60 amp breakers at sub panel which is how Tesla diagrams it. It works. The WiFi keeps the system from pulling more than the total 48 amps available

I’m going to add a Tesla universal wall connector at some point, probably outside. The current Gen 3 works great on both the Y and Lightning (A2Z adapter), but we only have one open garage space for charging. I was dumb and didn’t buy the universal version when we got the Tesla in March 2024, I didn’t anticipate getting another Lightning. The outside charger will be able to connect to my main panel rather than the garage sub panel, so I won’t need to worry about only sharing from the 90 amp garage sub panel.

The app is notorious at being wrong. I wouldn't trust that number.

Your still limited by the total amps from main panel, unless you have more than a 200 amp main panel you could try and use 2, 60 amp circuits, one for each wall connector so you would get the full 48 amps each but you would have to check how many amps your house uses or you could start blowing the main circuit if you use more than the 200 amps, if so then you would have to power share or set up lower amps for easy wall connector. Power sharing works great for me and both the Tesla and lightning are fully charged by morning off one 60 amp circuit from main panel to sub in garage with 2 60 amp breakers per Teslas instructions.

very cool setup with these new universal wall connectors. the last one on the line can be a gen 3 wall connector..

Wow, that’s neet I got my universal wall connector after I got my gen 3, so I just power shared off the gen 3, so I have a breaker box I wouldn’t need if I started out with universal. I wondered what that extra set of connections was for
