The battery disconnect does NOT disconnect all the 12V parasites. The only sure method to avoid dead batteries in the spring is to remove the negative battery cable.

The newer converters do a good job of keeping the battery tended without boiling out the water *IF* you have power. Mine is always plugged in, even when stored here at home.

As for the impact of solar, I can't help you. It may keep the batteries charged too if there is sun. But I have no idea. Surely someone with a new solar equipped rig will be along to help.
