Interesting topic, what l am seeing is over throttling which will potentially contribute to mid day clipping. Many inverters now can be overdriven by as much as 200% but the inverter will only produce it's rated output and 150% well that's right in there. But hey what do l know. Looking forward to other ideas Fun times
