I was powering our TV off my inverter last trip, and my son fired the onboard genny to run the microwave. It didn't seem to affect anything that I could tell
I think you were pushing your luck. Even if generator didn't damage the batteries because converter was off, it was still backfeeding 120V into the inverter.
It is almost certainly the case that shore power and the generator are connected to AC system through a transfer switch that only lets one or the other power the house AC at one time (generally it will choose the generator if both are on). At least no manufacturer would release a rig that didn't work that way.
So when you hooked your inverter up to shore power, and then turned on the genny, you were probably simply powering everything via the generator at that point, and the inverter was effectively disconnected at the transfer switch.
