Ok, right. In that case my guess is no, the Ford/Sunrun system likely doesn't support AC coupling with a third party solar. But I don't know for sure.
I believe that is correct.

Extremely unlikely IMO.But for the nested solution, the question is whether the Ford/SunRun controller is designed to deal with AC coupled PV when off-grid, e.g. when necessary can it throttle AC coupled PV by raising the frequency?
In particular because, AFAIK, there is not a standard for the raised frequency signaling across manufacturers.Extremely unlikely IMO.
Yeah we could really use some improvement there. For newer inverters you can probably use UL 1741 SA (or SB?) frequency-watt feature and the California Rule 21 guidelines. But yes, this is fraught and we don't know if the existing system will do it or how much hassle it would be set up.In particular because, AFAIK, there is not a standard for the raised frequency signaling across manufacturers.
Some more research is required, including tracking down the full installation manual, but my preliminary info is that the Ford/Sunrun solution is using a Delta E10_BDI inverter, and that its installation manual indicates support for AC coupling. To be confirmed.Ok, right. In that case my guess is no, the Ford/Sunrun system likely doesn't support AC coupling with a third party solar. But I don't know for sure.
We’re not. The inverter system is exponentially more expensive. I think the equipment alone is close to $10k. There is a Sunrun installer here in the forum that has shared some details on price and installation you can find in a search.My customer wants to use a bidirectional charger and add an inverter for backup, I'm not sure were talking about the same thing?

From a brief glance at the Delta one-line diagrams, the Ford Charge Station Pro gets installed on the utility side of the MID(s), so it will be see any grid outage and I would expect do its thing as usual. I'm considering the configuration where the Delta MID is the top-level (closest to the grid) MID. I don't see how the presence of another MID/PV/BESS downstream (away from the grid) of the Delta MID would affect the Ford Charge Station Pro's behavior.The inverter may be capable, but the Ford Charge Station Pro controls the DC contactors in the truck and its logic is to do so on loss of AC power. I don’t know if a workaround is possible or not.
I am not even sure if I(not being SunRun) am allowed to do anything and have it not void any warranties
