(i didn't mean to hijack the thread, just wanted to know a little more)...
No hijack at all, valid question, but one I really can't answer, as our solar panel & Controller was installed by a Solar company out of Lake Havasu, AZ so not sure about the serial or parallel connection issue, as we only have one panel.
I'm fairly certain there's an in-line diode on the positive supply lead between the controller and house battery bank to prevent voltage back flow when batteries are receiving a charge from either the converter or engine alternator.
The positive lead from the controller is connected to the house battery bank only, however, our coach's Battery Control Center has an isolator solenoid that engages, when voltage from any charging source reaches 13.4 volts or higher and charges both house and chassis batteries.
When voltage drops below the 13.4v the isolator solenoid disengages preventing battery drain from one battery bank or the other.
Best of luck and safe travels
