Jay, I may be thinking of a Photon Magazine article authored by an employee of SMA talking about in-house studies. So....what guide do we have in this wicked world for proper mod/inv design ratios? Was I such a fool to rely in the sources I mentioned? Would it have been wise to size to say, 75%? Would I have avoided most of my inverter failures if I had?

However I wonder if the "optimal" is for array to inverter sizing ( ie rare clipping ) but not necessarily for inverter reliability? jay peltz power
