two ac input at the same time on quarto

hello all

I have a question, we are installing a complex 3 phase system with Quattro inverters and we designed a special distribution board for it, everything is good but we have a small concern we want to make sure about :

in case both AC input sources are available at the input of the inverter at the same time will this make any problem for the inverter? and how will the inverter deal with it? will it neglect one or can that be done from setting?

the point is that if this is ok for the inverter then our distribution board will be simpler but if it would make a problem for it then we need to consider how we prevent this scenario using contactors and stuff

Read the datasheet/manual:

Two AC inputs; integrated switch-over system between shore voltage and generating set
The Quattro features two AC inputs (AC-in-1 and AC-in-2) for connecting two independent voltage sources. For example, two generator sets, or a mains supply and a generator set. The Quattro automatically selects the input where voltage is present. If voltage is present on both inputs, the Quattro selects the AC-in-1 input, to which normally the generating set is connected.
