This is also how it was explained to me. I am seriously thinking about some kind of transfer equipment that would allow me to use my solars in a power failure. I am really surprised they don't offer that as an option. Since you are only transferring a fairly small supply and it could be a manual transfer, I don't see this being that big a deal.
I foresee putting a few critical loads into a small sub panel, with the inverter and transfer equipment integrated there but I don't know if that is actually available.
I still have not had the solar guy over here for that kind of chat.
