What setting should I use

I have 2 Multiplus 120X2 in parrel. In the cerbo this screen

Should the values be for one unit or the total combined. I am thinking total combined so AC1 Connected would be 100A for a 50A service 50A on each leg a the no AC inputs would be 46A because each unit can do 23 amps.

I just noticed the auto-ranging at the top so if i get to those aps it should adjust. Or is it better to set what they should be.

I use auto range

These setting are only for the bars at the overview pages
