2016 arctic fox 811sb: wires from circuit breaker to tv, how

Crazy thought. Can I connect the wires for solar to the battery, then pick them up in the wall next to stereo? Not sure how that connects to roof wires. Anyone know how these 3 points are connected?

Seems I could connect the inverter where the charge controller would normally connect, no?

Don’t plan to run solar anytime soon but don’t want to screw it up in case I do in futture.
