The new inverters are WAAAY better. Current SMA inverters have 2 or 3 MPPTs so each string should have its own channel. The MPP range is also ~100v - 480v. So you can have any combination of 4 - 14 panels, just have to make sure that all panels on any string all have the ~same orientation.
+1 I got free micros from Renvu as part of a promotion and it was STILL almost as expensive as buying a string inverter because of the stupid trunk cable you need!
