You still need to understand what the existing isolator is doing and if it’s working. Although it’s 99% likely its supposed to isolate the house bank when the vehicle is not running.
You haven’t posted enough info to show that you understand what’s wired how, currently.
Once you figure that out, you can work to achieve charging the start battery off of the converter in the most efficient way.
IMO adding more aftermarket switches that no one will understand except you as long as you actually remember is silly. But he’s a simple solenoid switched to whatever you want it to be switched to is an option and not a bad option. It’s also not dummy proof like an ACR.
Take the advice here carefully as there’s some bad intel in other posts.
