This is my first time on a forum, so bear with me. How do you figure how many solar panel for a Growatt 5000w ES off grid 240v inverter, maximum PV input voltage is 450VDC and 6000w of solar power? I have 60 cell, polycrystalline, 250w, VOC 37.6 and I think 8.27 amp if I reading it right. I guess I don't understand the math, I have watched a lot of video, but maybe I'm over thinking it. Can someone explain it to me, thanks James.
