Installing Gateway 3V and Solar

[Ward L]

I am building a new home and incorporating the Cybertruck Gateway 3V I got when I bought the Foundation Series truck. I'm using a Tesla certified installer, who happens to be installing my new solar panels. The installer has talked with Tesla support and is being told the Gateway V3 does NOT work with solar panels, YET. When I go to the Tesla site, it says the Gateway 3V WILL work with solar panels. When I say, "works with solar panels", I mean when the grid is down, solar charges the truck batteries as well as powers the house. My installer says until Tesla releases the software, the solar panels will not work when the grid is down, even when the Cybertruck is powering the house. I am NOT getting a Powerwall battery. Does anyone have any first-hand information about this? If it matters, I am using the Enphase IQ8AC-72-M-US microinverters. HELP!

Moving this summer and looking to do the same thing. In addition, I'm going to be removing my Gateway and my two connectors. (The Universal one for my truck and 3rd gen for the Wife's MY)

I hope it isn't hard to find someone who can add panels and MAYBE a power wall at the new place.

Good luck with yours. I'll be following for updates!

your problem is the enphase micro inverters. If you were using the Tesla inverter, I'm sure it would work. Micro inverters are down when the grid is down, unless they are paired with the enphase battery.

I did find this on google AI, sounds like maybe if you have the enphase gateway to communicate with the enphase micro's and the tesla gateway to communicate with the Tesla battery, then just specific wiring can connect your micro grid, to your micro solar array.


you can integrate Cybertruck PowerShare with Enphase microinverters and an Enphase IQ Gateway, but it requires careful configuration, ideally with an Enphase System Controller (or IQ System Controller) and potentially specific settings in the Tesla Gateway for smooth off-grid operation, as they both manage microgrids and need to coordinate not to create conflicts or shut down, with IQ8 microinverters being best suited due to their ability to form their own microgrid and match loads automatically when the grid is down, according to this Reddit discussion and this Facebook post. The key challenge is ensuring the Tesla Gateway (often part of PowerShare) doesn't interfere with the Enphase system's grid-forming capability when the grid is out, which might involve wiring the solar before the Tesla Gateway or limiting PV production via the Enphase Gateway.
How it Works (and Potential Conflicts):

• Enphase IQ8s are Key: IQ8 microinverters are designed to form their own microgrid and adjust power output to match loads without a grid reference, making them ideal for off-grid scenarios, say {Link: users in a Reddit thread.
• Tesla PowerShare (Gateway/Cybertruck): This system also manages a microgrid when the main grid fails, often by sensing grid loss and activating the truck or battery.
• The Conflict: Without proper setup, the Enphase system sees no grid and shuts down, while the Tesla system might activate, creating an unstable loop or shutting down power.

Your timing is great.
Foundation series , Solar with enphase micro-inverters , No power wall.
After almost 2 years after 3V installation as of last week I now have PowerShare working .
So it does work and Tesla should be supporting it. Took forever and a day to get it working with Tesla but hopefully you will not have to wait as long when your ready to install.
I have the very old micro-inverters 8+ years old.

Awesome. I think I better contact Enphase tech support. Thank you for the info. I have not bought the IQ micro inverters yet. I wish they made an inexpensive mini-battery that would carry the load for the short time it takes the CT to back up the house. That is another thread…

Just to be clear, when you say "PowerShare Working", do you mean the CT powers the house and the solar charges the CT batteries during the day (assuming there is excess solar energy)?

Yes, this appears to be really good timing....

To add more clarity —-when testing the PowerShare you have to manually go offline Using the app and you are supposed to turn off the solar breakers Prior to going offline/offgrid.
That is the only way to test it without an actual power failure.
There is about a 5 second delay in the changeover.

Tesla is fully aware of my configuration and set up so I would expect that with power failure and solar on it would either use the solar energy to help power the house and or charge the battery. The energy has to go somewhere and my system is only 5kw.
If I recall correctly the inverters look for the line frequency to be preset before re-activating

I only have this functional as of last week so have not seen an actual power outage yet to confirm.


I do plan on adding a surge suppressor to the CB panel soon to hopefully suppresses any large current surges during transition.

I will follow up if I learn anything more .

I'm no expert, but I think the best setup just use the Powerwall 3 as the gateway, with no stand-alone Powershare gateway. Then when Tesla releases the software update for Powerwall 3 later this year, it will work as desired with the solar during power outages.

Powerwall 3 would still need a Gateway 3 or Backup Switch.

@Ward L : UL1741 solar of up to 11.5kW works with Powershare:

If that timeline is accurate, I would tend to agree. Tesla has a tendency to, two weeks something for a decade.
