Adding Circuits to Tesla Panel?

[brian954]

So I’m trying to I add a mini split AC unit in my house and I need a 220 outlet to power it. I have Tesla solar+powerwalls.

The side of my house that needs the outlet is on the complete opposite side of the house from my circuit breaker panel but is on the same exterior wall as my powerwalls/main electric box/Tesla added panels.

The electrician that I asked to quote the job for me took a look at what I had outside and suggested that we add a breaker to one of the Tesla panels to draw power from there.

Has anyone here done this? I’m not sure what the panel is called but it currently has 4 breakers labeled: Main, solar, batt1, batt2.

Pricing to run all the way to the main breaker will probably be insane and even more so if I want it done with our exposed conduit everywhere.

Thanks for any suggestions/input!

Can you take a picture of the label?

I have a similar panel. It's a load center that takes the feeds from solar and PW and is wired into the gateway. Mine has a label "Do Not Add New Loads".

OP, is your entire house backed up or is there another panel. I'm not saying you should do it, but if parts of your house are backed up and you add a breaker to the solar/PW load center, the mini split will be part of the back up.

Sure, photos attached.

My entire house is backed up and I was hoping the new mini split would be backed up as well. Only my main panel in the garage has the “Do not add new loads” label.

my entire home is backed up and i added a 240v 30amp circuit for Hybrid water heater to the load center .. there were 2 slots open (to create a 240v or 2x 120v) on my load center (labeled with the warning do not add loads) ... my experience
i had an electrician (relative) do calculations using the orig tesla calculations that i still had from tesla paperwork .. we then contacted tesla to see if they agreed with his calcs / and to be sure no warranty issues down the road .. tesla of course took forever to get back to us.. so we proceeded with adding the circuit and few days after we completed it Tesla finally got back saying it was fine to add circuit
the mechanics of adding the circuit is no diff than adding a breaker to a panel . simple enough .. its just the added load calculations .. I actually did work myself w/ electricians supervision

Sure, photos attached.

The panel in the photo is full and appears to be a panel for just generation sources, not loads.

Do you have the one line diagram from the Tesla permit work? It certainly should be possible to add another panel next to those to supply new loads in the vicinity, if that is preferred over connecting to an existing panel much farther away.

Thanks, I’ll have to dig up my original documentation from the install.

I was quoted with two options, 1 was a double breaker in panel in the photo. The other was to add an additional sub panel.

Show us what's inside that tall painted panel on the right.

That one is a single 150amp breakers, turns off the main connection to and from electric company.

Where are all your load breakers then, in a panel on the other side of that wall? Is there any room in that panel?

You could replace the existing 100A (assumed) generation sub with a larger 200A unit with a 100A main breaker. This way you would have physical and electrical room for the new load.
