Re: "You can't hook an inverter to a neutral that is connected to the Ground wire.
it will be a Short Circuit to the inverter and it will Blow Up."

On older inverters the neutal floats and this is true.

However,
Many new inverts this can be done and it's required to pass code (So I'm told). You really need to contact your inverter manufacture for their specification.

Example: My AIMS 3000W pure sign invert I have the neutral wired to my main panels ground bar.

How about the idea of the out going AC's neutral (from the first inverter) being wired into the second inverters out going AC's neutral? I can separate the hot legs but not the neutrals. Would they effect each other?

I'm starting to understand your question. Are you attempting to pull power from both inverters at the same time to the same circuit? If so your going to have to match the phase output of both inverts to accomplish this that is not an easy task.
If you wanting to power two seprate circuits but have the neutrals both wired to the main panel ground bar that is only possible if you inverter is designed to have the neutral grounded. Depending on your particular inverter. If they don't support neutral grounding you'll smoke both of them. I would contact the maker and ask them can the neutrals be grounded. If yes your good to go as long as you service the hots to different circuits.
