I would NOT connect both Fronius inverters after the Victron inverters (on the AC out), because this would be 16 kW of power on the output of a total of 9kW battery inverters and this is not allowed, because it might/will break the Victron battery inverters. See this webpage: https://www.victronenergy.com/live/ac_coupling:start
You could connect 1 Fronius 8 kW on the front (AC in) and one on the back (AC out) that will be OK.
