The Sunny Boy 4000TL spec gives max dc power in 4200w. Can anyone enlighten me as to what happens when your array size is greater than 4.2kwp? Or more specifically when the dc power in actually exceeds 4.2kwp. Sunny Design result for 4.9kwp is more than acceptable, because presumably the array is harvesting more energy for 90% of the time and will only rarely peak above 4.2kwp. But what does the inverter do at these times? Does it simply clip the power (in which case where does this power go?), does it shut down? or does it somehow electronically feather it by rapidly switching on/off (forgive my lack of technical language). And further, would this process result in a shortened life for the inverter?
