Hello all! I have an existing setup with a Tesla Gateway 2, (3) Powewalls, and a SMA inverter supporting a 9kw PV array... this is the 125AMP panel I have where the powerwalls are terminated via 30amp breakers and the PV array is terminated via the 40 amp breaker from the inverter: I am...

BTT

Like the title says!

PM'd! I want this!

The CT for my solar is in between the inverter and the solar/battery panel... so I assume I'd just grab another CT and add it to the same location with my new inverter? Are these Tesla parts purchasable online somewhere? What about phasing between two different inverters? Do I need to worry...

I have a 9k PV array connected to a SMA inverter and then into a dedicated panel.... I also have 3 powerwall batteries connected to that same panel. That panel connects in to a Tesla Gateway. I'd like to add additional PV solar panels... I assume I can just take that new array into a new...

...and yes, that is correct. Founders Edition craigslist find.

Not sure about that... I have a brand new Gateway here I could test with if I get bored ;) Warranty is no issue.. Tesla has already added it to my account.

I have a brand new Backup Gateway 1 for sale. The Tesla rep I've been working with says no issue with selling it and transferring warranty to the new owner. Anyone interested?

Transformer is super close to my panel actually so I think I'm good, but trying to get that number from the installer anyway just for my own knowledge.

Appreciate it! 400amp.. waiting to hear back from installers on the actual number (assuming they logged it somewhere). But when I told them I wanted to add more they said I'm well within spec.

I've got a brand new Backup Gateway 1 sitting in a box... let me know if you're interested. The Tesla rep I was working with said there is no issue with my selling it and transferring warranty.

Grid impedance is the only thing I'm waiting to triple confirm... all else looks good... during install I was told I could run as many batteries as I wanted basically (so I assume going from 2 to 3 I'm still well within spec), but I want to confirm that again. Thanks for the help!

I appreciate it! Should be all good, but I'll triple check the above!

Just to be clear.. I initially tried to login with installer creds but it asked for email and password which I didn't have. Someone sent me a private message and explained a little more and when I looked again, I realized I could log in as installer with a simple power switch toggle (similar to...

Done and done. EXTREMELY simple. I don't quite understand all of these responses from people who really don't know the answer, but try and give one anyway. I didn't realize the installer login could happen with a simple power switch flip, so I was able to get in, provision my battery, update...

So the "installer" login on the Backup Gateway is not necessarily the original installer, it could be any certified Tesla installer with an active installer account?

And.. lets assume my installer no longer exists... what would the process be then? Factory default the Backup Gateway and start over?

Correct, I physically installed the third battery and wired it up. Just trying to figure out how to provision it on the Backup Gateway now.

Had 2 Powerwalls and a Backup Gateway 2 installed by a big name solar company. I just added a 3rd battery in to the system, all connections are up, but the third battery is flashing green and doesn't show up in the app. I assume I need to re-run the install wizard, but when I connect to the...
