The disconnects typically used on solar are called MC4 and can be terminated DIY though it might be easier to just use a gland fitting and ring terminals which can be pulled through the fitting. Just cap the gland when the wires are removed - or don't.
You're saying that the switch does not turn off the house bank? I was under the impression that it turned off both banks. Maybe not. There are a few different versions it may be helpful to provide a model number.
