Another solar controller question

Some controller manuals warn about running a load without the battery connected. If you still have the array hooked up and disconnect the battery, depending on the set-up, you can have the load running from the array via the controller, which is a no-no with some. It might be a bad idea with all of them, if not exactly harmful, don't know.
IMO put a simple switch in one of the array wires by the controller. Then it is easy to open that switch before disconnecting the battery. That is, if you can get at the controller! Some are inset to an interior wall in the RV. Not easy to get at. In that case you have to disconnect the array up on the roof maybe.
All good reason to have the controller close to the battery for short wire run, ease of connections, and handy.
