FWIW, we have a similar issue on our '15 Windsport 27k. So far, we haven't tracked it to any specific power or battery issue. Our leveler panel constantly goes into a "low voltage" or "return for service" status. Had service techs look at it last fall, and all they did was reset the panel. It works like a charm with no errors at all as long as we're on shore power; but wouldn't trust it on coach or generator power.
