gateway 2 rolling out in US yet?

[GenSao]

CT? no clue please illuminate!

@SMAlset : CT = Current Transformer. For the Tesla Energy Gateway, they are used to monitor AC power flow of the grid, solar, and other devices in the home.

It's interesting that they have fixed the Grid CTs on the input bus bars. My Gateway 1 came from the factory with the Grid CTs installed on the input side of the switch, but they were relocated by the installer to the main panel so that my non-backup loads could be offset by the Powerwalls when the grid was up. I wonder if the Gateway 2 has additional CT channels (or you have to disconnect the factory installed ones) to support measuring the actual grid main, or if you have to feed non-backup loads from the provided lugs so that it is measured correctly.

In my v1 Gateway they just left the CTs by the transfer switch in place and installed 4 external ones. So there are just two disconnected CT wires inside the Gateway. I'd assumed those two were permanently mounted, I guess I'd have two free CT's if I dared to move them away from the bus bars.

I find it quite interesting there are non-backed up lugs installed as a default option. the 14-2 AWG note implies only 15 A circuit(s) can be installed. There must be enough use cases to warrant them installed on all Backup Gateway 2 units. I wonder what they are...

The range is from 14 gauge (smallest) to 2 gauge (largest). 2 ga is good for 115A using THHN 75C copper.

Thank you for the clarification. Up to 115 A is good for many items, even a wall connector or two.

What’s the sub panel for? I’m having my power walls installed in my garage and have the need for a sub panel for my impending pool. Can I add that to my installation?

 

[Vines]

The internal subpanel may rarely be used for metered backup loads but its limited in the slots, most likely its for generation sources.

If your pool isnt backed up but has a big draw, use the 100A non backed up lugs to feed a small 100A sub with 100A main breaker.

Can the internal subpanel be hooked up to the non backed up lugs?

All I’m really trying to do is avoid running a separate trench back to my house (detached garage) so if I can tap those lugs to a separate sub panel it will save me 2k in trenching.

Yes, but it requires a Main breaker, so leaving only 2 slots/4 spaces remaining.

Well, they are here for my install and unfortunately it looks like I am getting a Gateway 1 even though the design called for a Gateway 2.

 

[gigawatt1010]

I remember you posted a screenshot of your layout saying GW2. That blows - did they give an explanation as to why?

Damn really? Is there an official installation guide posted anywhere for the Gateway 2? I was supposed to have my Powerwalls installed today and they did show up with a Gateway 2, but cancelled the installation due to some existing damage in my main panel. We talked over possibly using the GW2 internal breakers to replace the big 200A generation panel they were planning on installing, when they come out again. But it sounds like this may not be possible if I need to land 3x PW breakers + 2x solar breakers there.

In my case they put a little 125A solar panel for the breakers from my two inverters, then a disconnect switch, then the 200A generation panel with one solar breaker and breakers for the four powerwalls.

I'm glad that I've found this thread. I called Tesla 2 days ago and found out that my order was going to be gateway 1. They put an urgent request to change it to gateway 2 and surprisingly they were able to keep my appointment and get it installed today. I'm in the bay area. Thanks guys!

 

[BrettS]

When I first saw your picture I thought your powerwall was plugged into the 120V outlet next to it. I was a bit confused for a minute. The install and the gateway 2 look great though

 

[gigawatt1010]

That's great @druken

I called them last week and they were able to change mine from a GW1 to a GW2 as well. At least it's reflected on my layout docs now. I'm still on the permitting stage though.

Haha, yea that's the plug for an outdoor camera. Thanks, it looks nice and installation was very quick (~2 hours).

That is really quick. My install was closer to 19 hours over two days. Although to be fair in my case they were installing a little more equipment

Bay Area?! That’s great news for us, still awaiting scheduling. We asked in the beginning for GW2 if available so guess there’s hope we can get it. It will go inside our garage with our PWs And really never wanted a gray box installed inside.
