Its hard to say, if your batteries are fully charged and in good shape then the inverter doesn't really care if it has AC voltage or not. But it is strange it only does it with generator so I would check the automatic transfer switch first, could be some contacts need some sanding or filing which is creating a low voltage which the inverter see's and shuts down.
