Here's a brief timeline.

1/28/21 - Project finished on
1/28/21 - Permit Re-submission due to redesign and inverter change
.
.
.
3/31/2 - Tesla & City Final Inspection
4/1/21 - Permit Finalized
4/2/21 - New meter installation scheduled & pending

After 2 months of waiting we are close to PTO. Tesla just sent me the invoice for remaining balance, do I already pay this or should I wait for the city to install the new meter? Also, when does Tesla provide me the solar gateway box?

Is your job a solar roof? PV and PWs here.

We got our little black solar gateway box early on. Maybe when the solar team first came out?

I’d let them know if they didn’t leave you one.

With our contract we didn’t have to pay until we received PTO. Think things might have been worded differently for some depending on contract time. We also had to remit half payment at time they first showed up so already had a good chunk of our money although we had all their installed equipment before paying. Our meter was already updated to a smartmeter about a year or do ago so we were just waiting for approval from PG&E with inspections already completed.

Congrats on being at the finishing line! Changes your life in how you use and think of electricity especially if you added PWs.

Thanks! We got the solar roof installed, actually ordered back on October 2019 but the pandemic hit and decided to just delay it. We definitely cannot wait to get it working, already wasted 2 months of sun and counting. I just read up on the contract and its due within 5 days of inspection, looks like I'll have to pay up. It just makes me nervous since Tesla's communication is abysmal when something comes up. Hopefully all is good once its up and running with no more delays.

This post has a diagram of the setup with the new Tesla inverter:

Pay it soon since Tesla will not send the PTO request until you pay even if everything is ready to go.

Regarding the gateway do you have Tesla inverters or Delta? I believe only the Delta inverters need a dedicated gateway since Tesla inverters have Wifi built-in. Inverter connectivity is separate from the Tesla Energy Gateway that gets installed as part of a Powerwall installation.

Could be worse. We had an operational roof in April and got PTO in late August.

I have the Delta inverters, so I do need the gateway box. My installation was like this, during the whole process I always had to chase down tesla for things, just like when they came back to install the powerblaster, the person who did it did not connect my AC breaker so days later when it was hot, turned on my AC it was only warm air, I troubleshooted, opened up the electrical panel and there it is... however, they do a great job once they are here and are very nice, but I do realize its a minor annoyance as some people have it worse. I actually preferred to have the Tesla inverters but that was announced the day they were tearing off my roof, my project advisor said can't be done so I had to stick with the Delta.

Ok - if you have Delta inverters, then the electrician should have brought you a solar gateway box too. I had the most success dealing with my install project advisor (as opposed to the sales team in Vegas), so if you have that person's contact information I would recommend trying to get the gateway through them. If that fails, I would try the Tesla Customer Care group (725-867-6182) who is responsible for support post-install. I found the sales folks to be least helpful/responsive.

Then your system is like ours. Just have them send you or drop off the inverter gateway. It is an owner-installed black box (5"X5").

They gave it to me and I connected it to a Cat 6 cable from my router. You will also need AC power for the unit. Ours is installed inside the garage and on the outside of the same wall are the inverters. The box has a relatively short range so you need to get it close to your inverter. They told me 100 feet with no wall was about maximum. With a wall, they suggested keeping it within 25 feet. People have gotten away with further, but I wanted to ensure a good signal and ours is within 1-2 feet of my inverters since the inverters are on the outside of the wall and gateway is on the inside, and they stucco walls have wire that makes them like a Faraday cage

FWIW, we also have Powerwalls and I don't think we can see any of the data the inverter gateway provides. The Tesla app data comes from the Tesla Energy Gateway (TEG) they install as part of the Powerwall and is an aggregate of the outputs from our inverters. We don't see any readouts from a specific inverter. If I want Delta inverter-specific information I use the Delta phone app and stand very close to the inverter.

That is my understanding as well - the solar gateway's purpose for PW customers is to handle inverter firmware upgrades. All of the production data comes from the Tesla Energy Gateway (and it appears Tesla is now calling this the "Tesla Backup Gateway".) If you have PWs, your system should generally operate normally even if the solar gateway is not hooked up.

In our case, the one thing our electrician did not tell us about was the existence of the solar (non-backup) gateway. I found it several days later on a shelf in our basement and asked the crew lead (who was still on site) about it and was instructed on what to do with it. So it might just have been misplaced or lost by Tesla during the install process.
