You can get a dual input PDU that will auto switch between sources, connect one input to the ups, the other to a generator circuit. I haven't bought one in a while but tripplite used to make them. The tripplite units were designed for rack usage and are not cheap, so may not be the right solution for your needs, but I'd hope there are some less expensive equivalent systems for home use.
