PowerWall and Gateway - Electrical Diagram

PowerWall and Gateway - Electrical Diagram

I was wondering if anybody has any detailed electrical diagrams for the PowerWall and Gateway?

I had signed a contract with Tesla to install my solar system (panels plus powerwall etc), but yesterday they informed me that they wish to cancel the contract due to the fact that I have a clay tile roof (which almost every other house in southern California seems to have).

Anyway, since I am an electrical engineer with lots of power experience, I am thinking about buying the PowerWall etc from Tesla (installed) and doing the system integration myself with the solar panels. Heck even the solar panels that Tesla uses are not theirs.

They have sent me a couple of pieces of literature (Powerwall 2 AC Owners Manual, Powerwall 2 AC Datasheet, and Backup Gateway Datasheet) but the diagrams in this literature is simplied at best. If anyone has an installation manual or something like that they could share, I'd really appreciate it.

Also - does anyone have an actual photo of the Tesla backup gateway, I'd be interested to see what it looks like.

You can find a local solar installer for your PV system and have Tesla installs PW2 at a later time. On the other hand, I don't think Tesla will sell you a PW2 for self install. It has to be installed by a certified installer.

Has anyone installed ferrite chokes on L1 and L2 in the gateway? I have been experiencing connectivity issues between Enphase micro inverters and their “Envoy” monitoring unit due to RF interference coming from the Power Wall ( as per Enphase tech support ) They suggest installing 2 wraps of ferrite chokes on both L1 and L2 in the gateway. Has anyone done this? what size chokes did you use and where did you place them along the lines?
I belive wiring is 6 AWG.

Does anyone know when the Powerwall 3 will be available in the US?

Seems like a question for Tesla Customer Service, but *call* them. E-mail contact returns are spotty, at best.

@paulreif- now I am worried as I also have Enphase Envoy but it may be closer to the PV system; however, I rather not find out after the PW install in the near future.

I am interested in integrating Portable Generator with Solar PV + Tesla PowerWall 2. Powerwall 2 will feed only essential circuits during PG&E outage.Does anybody have a circuit diagram that can be shared here.
Thank you in advance.

Someone already asked the question about operating a generator and a PW2 together.
It's not possible. The systems are not designed to operate together. The problem is the way the Gateway controls the DC-AC inverters inside the PW2 and the Solar and makes them work together. The portable power generators don't allow this kind of interaction. Some generators use inverters (high quality ones) and some others don't (don't even try to use a cheap generator!).
