When designing a 3 phase off grid system , can one put 3 single phase PV ‘s on the output of each? Do you need to disable “switch as group “. Further can one add a single phase generator ( or single phase grid ? connection) and then disable switch as group?

Yes you can do all of that, as long as you dont have 3 phase loads, you can turn off switch as group
