Not allowed. You need a dedicated OCPD. Plus seems like a really bad idea.  How do you shut down just one inverter?

Since there is no OCPD on this wire, would we have to use the same wire gauge as the combined output? or can we get away with sizing each wire according to its associated inverter output rating?
