It depends on the controller for sequence of power to the controller from batteries and from the modules. I think some of the cheaper controllers don't like the modules connected with no power from battery. A switch on both solar and battery would be easiest.
In the two bank configuration, I used three dual bank switches, one from the solar controller, one from the converter, and one to the inverter. I used a single pole manual circuit breaker between the module and the controller.

? about using one of these battery switchers with a solar controller.
My two controllers specify that the batteries are connected first and then the solar panels. The connections on one are actually numbered:
1. Battery -
2. Battery +
3. Solar -
4. Solar +
It is my understanding that the solar controller is powered by the battery. Disconnecting the battery should follow disconnecting the solar controller(reverse order of installation).
When operating the battery selector switch in a break before make mode, doesen't there exist a time when no battery is connected to the solar controller. Wouldn't you want a break switch on the controller before switching battery banks?
