How to ground multi inverter setup

[Aridom82]

Hi i live in Italy and i am installing 3x Voltronic Max Axpert 8kw inverters at my house.
I have 3 phase power installed so i am putting them together to generate 3 phase power. One phase each inverter, like the manual indicates.

However the manual does not say anything about the ground wires. Between the AC IN and the AC OUT of the 3 inverters i have 6 ground wires.
Can i run them together? The main panel and main ground are 2 meters (6 feet) to the left of the inverters.
All wires are 16mm2 (6 AWG). Thanks

Yes, they can be tied together.
Also, you only need one wire to each unit. (Input and output are tied together internally)
The two terminals are provided for pass through uses.
