Jeff, i've never seen anything but VS (inverter) or 2 stage/step in a <5 ton standard split system. the only application i'm readily familiar with digital scrolls in is CRACs. I don't see those as a good fit for purely running on solar - they modulate the scroll on/off full load, so if it's not actually grid-tied, it might be a problem. otherwise average draw should work for % modulation.
