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

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

When charging my Lightning myTesla wall connector reports 11.7 KW output on the Tesla App and the Ford pass app reports about 10.6 kW. The difference is the Tesla reports the actual output and the Ford reports charge accepted by the Ford battery after efficiency losses. Typical loss ranges between 5% yo 10%.

My most recent charge history on 2/1/25
Tesla app reported 25.4 kWh delivered
The Ford app reported 23 kWh added.

Prior charge session 1/31/25
61 kWh on Tesla app
56 kWh on Ford Pass app

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.
Pics to follow….

Greg,

Thanks for posting this. I think you just cost me $550.

Our EV history is similar to yours. Original Schneider L2 30 amp/7.2 kw output installed 10 years ago to charge Nissan Leafs. The Schneider was replaced with a Tesla Wall Connector wired to a 60 amp circuit 2 years ago when we got first Tesla.

Now we have 2 Tesla Model Ys and a Ford Lightning. At our house the Tesla Wall connector charges all 3 only one at a time. As simple as power sharing is I’ll likely buy a Universal Wall connector and install it in the existing location and run wires from it and relocate the original gen 3 Wall Connector.

The load sharing ability that the Universal Wall Connector has with an input and output connection eliminates complexity of needing a sub panel to split the power to each device. I can install them side by side with minimal expense. Then I have ability to charge any combination of 2 of our 3 EVs at once. I like it!!

The Tesla Universal Wall Connector was introduced 18 months ago.

so, here’s the install. Universal Wall Connector on the right, Gen 3 Wall Connector on the left. Universal has wiring pass thru for daisy chain connection. Works perfect. The built-in NACS/J1772 adaptor is really nice. Just un-holster the one you need.
The conduit change (for the truly observant) was because the first elbows were so close they wouldn’t allow the unit faceplate back on. Didn’t see that coming. Lol.

Looks good. Theoretically it’d be very straight forward to swap my Gen 3 for a Universal and add the necessary conduit to install the Gen 3 on the other side of the garage door. The conduit run would be about 20’.

Exactly what I did. The new Universal unit literally used the previous existing mounting holes from the Gen 3 baseplate.
Super easy addition, with PVC conduit, although not quite as elegant looking.
Took a couple trys to set up power sharing feature via the install app.
The key is to disconnect phone from home WiFi and disable home WiFi auto connect. Then scan the Universal “leader” QR codes, making a connection with the units to update software, make setting for sharing and then scan the QR code for the follower and update its software if applicable. Then unit setup is finished.
Reconnect your phone to your home WiFi.
At that point you can connect them to your home WIFI in the Tesla app, for data monitoring and remote control. Or not.
If you don’t connect them to your home WIFI, just let them be unmonitored stand alone power sharing charger units.

Oh yeah, Tesla does want pics of install uploaded to them during the setup process. No big deal. I uploaded really basic pics.
May be a way to get around that, IDK.

Thanks for this. I had planned to do the shared setup, but could never find clear instructions that the electrician would accept. Side note, it's my understanding that a universal wall connector is not required, that two version 3 are fine. My understanding (possible incorrect) is the universe units internals are the same, just has the adapter.

YES, Sort of!!

The base mounting plates are different an not interchangeable.

The Version 3 only one possible connection to land each wire input
The Universal has 2 available connections to land two wires per input. This makes "daily chaining" them easy.

YES you can configure 2 or more versions 3's BUt you can't easily daisy chain them. You would need a junction box or a sub panel to split each line to two or more inputs, depending on how many Wall Connector's you want to power share.

See pictures below.

I sent to a PM with a technical question.
