Battery (really solar panel) Disconnect Question

Would like to put a simple battery disconnect switch between my charge controller & the house batteries vs between the rooftop solar panel & the charge controller.

Any potential issues doing it this way?

Back Story: Solar was installed prior to me owning the coach & the way it was done leaves me no good access to put a disconnect switch between the solar panel & the controller, at least not without turning this want into a major project, which I'd like to avoid if I can.

OK, gotta ask.
Under what conditions would you need or want to disconnect the solar charging equipment from the batteries.....except for maintenance maybe ??
Well designed equipment should cause no problem if left connected 24/7.

I installed battery disconnects between the array and the controllers, and a single disconnect switch between a busbar serving accessories (MPPT, inverter, etc) and the battery bank. That gives me full flexibility.

I would try to avoid that.

Some controllers can be damaged by leaving them connected to the array side and disconnecting the battery side. Check the controller's manual on that. Eg, Morningstar warns about it.
