On a new installation, I am unable to run any input on AC Input 2 (Generator), with Grid connected to AC Input 1. System: Quattro 8kVA, Generator 5kVA (Current limited to 16A), Venus GX, 2 x MPPT 150/100, 4 x Pylontech 3.5kWh and 30 x 320W panels.
I have tried swopping AC Input 1 & 2 (i.e grid on AC Input 2) but with no success. Any ideas to resolve this issue without sending the inverter back to supplier? (My client runs a animal hospital on this system.)
As long as the grid is available at AC IN 1, AC IN 2 is not used.
Only you have a grid failure at AC IN1 the Quattro will switch to AC IN 2.
You maybe have to adjust the settings for the AC input to accept the generator.

I've had TWO Quattro 10Kva units fail in the last 2 years with regard to AC Inputs.
Not happy...
