a grid tie inverter doesn't really help me with my issue which is starting the air-conditioner compressor when the generator is in "Eco mode".
My inverter does that.
My inverter starts the A/C too... the point is that my solar can't because I only have 320W of it.
So, beyond starting a large inductive load... what might the benefits be of paralleling a grid-tie solar inverter to a (grid-tie) inverter-generator like a Honda EUXXXXi?

That's the main point I was thinking off - using solar when just a few watts short to start something up. I was also thinking of using it if the camper is in a place where it is plugged in. you could offset the cost of parasitic loads or even provide a little surplus energy back to the grid, if you don't need that power for battery charging or you have a surplus.
But but there is a potential savings around fuel efficiency in a genset usage scenerio. Solar grid tie would let the genset burn less gas when running than on its own. It can be more efficient to generate AC right from the solar without the battery, controller and battery bank inverter in the equation. Even more so if the solar controller is PWM and the grid tie inverter is actually MPPT - the batteries can be switched out of the loop to let the PVs run at maximum efficiency.
So one use case is running the genset for something other than battery charging, and wanting to use as little gas as possible doing it.
