If the amp has a ground on its power plug (i.e., 3 prong plug in the US) and it plugs into a grounded outlet on the inverter, then the two chassis grounds
are connected. But if that ground reference isn't
true ground (floating voltage reference susceptible to picking up noise) it won't help any.
True ground = zero voltage potential. Grounding the inverter chassis would do the same thing as grounding the amp provided the amp's power cord has a ground prong. Again, my recollection of European 220 VAC wiring is dim as I never worked there.
