Interruption of the solar converter can also be before the controller, between the modules and controller. It's not necessary, but convenient.
FWIW, I have the solar controller, the inverter, the converter, and the batteries, of course, all on one bus. Circuit protection (fuses) are all at the bus and the battery is fused at the positive terminal.

So it's OK to have the negative wire from the solar charge controller to the negative buss behind the converter and not to the negative battery terminal?
