I used circuit breakers between the solar panels and CC and CC to batteries.
The few controllers that I am aware of with an on/off switch it only controls the load circuit.
For the most part I leave the 2 100 watt roof mounted panels on all the time.
The charge controller, CC, I have has a float mode which is like a trickle charger.
If your batteries are flooded, wet cells, check fluid level once a month until you get a feel for things.
