We are in the process of wiring a house with a Homeworks system. The house is also going to have a utility interactive PV system with battery backup. They would like the lights on the ceiling fans in the bedrooms to be backed up by the the PV while keeping the actual fans on the standard utility panels. The potential problem that I see is that ceiling fan/lights usually only have one neutral for the fan and the light therefore I would have neutrals from two differnt systems tied together at a common point. I couldn't find anything in the code book that prohibits it, but it seems like a bad idea. I am wondering if I am just being paranoid or it could actually cause some problems? I am going to suggest that the fans and lights be connected to the PV system but it still has me curious.
Thanks for any thoughts.
