You may have neutral and ground connected at more than 1 location, meaning at the genset and in house panel, which means the ground is carrying current back to the generator in parallel with the neutral.
I remember with some Honda portables we had to float the neutral at the genset or the inverter would trip the generator's GFI when trying to charge the batteries.
