Received PTO on my 8.16kw system late last week. Finally had some great sun days over the weekend. 24 340w panels in a 5x5 rectangle and a Delta M8 inverter. Facing due south on 20* pitch roof. Max output has been 4.1kw and it has already reached that today. Not seeing any type of bell curve for output. Definitely looks like clipping to me and only half the panels or only 1 string is reporting. Thoughts on how to fix?
