attaching a solar panel to a caravan

Maybe.
Only you can tell how the Anderson plug is wired. We have no idea and can only guess.
Also, it is best if the regulator for the portable panel (or any panel) is close to the batteries.
Cheers,
Peter

Maybe best to connect a portable solar panel, through a dedicated Anderson plug, wired together to the input of the solar controller in parallel with fixed solar panels if they are so fitted.

I once tried the opposite - connecting the Anderson plug from the tow vehicle to the solar input on my Enerdrive DC2DC in the van (long story). The DC2DC did not like it. It expects a higher voltage on that input and threw an error. My hunch is that what you're proposing would also cause an error for the opposite reason.
