Question: I want to design a PV system for two different roof pitches (and/or orientations) using only one inverter. How do I do that in Polysun?

Open the inverter catalogue and select a suitable inverter (checking the maximum DC power) with two MPP trackers (column n. 22). You can use the filter to find them more easily.
After having selected the inverter you will be able to define the orientation and/or tilt angle separately for the two MPP trackers:
