Combining Bluetti with built-in solar in RV

We got an AC200Max to use with an older travel trailer. Unplugged lead battery, plugged in 12V output from Bluetti, and plugged in a foldable solar panel. Sweet.
Now we have a new camper with a solar panel built in, built-in charge controller, and AWB house battery. I can do what I did before. But, I’m assuming my AC200Max will not charge through the output, so It’s not going to get power from the roof. Is there a way to connect so that I get the benefit of both solar panels to my Bluetti that doesn’t involve removing the RV charge controller?

@Bumbee You can reach it by purchasing a D050S, but honestly it’s not an economical approach.

Thanks. As I look at it, the D050S would let me charge the AC200max but not really integrate the two systems.
