Does anyone have a good >200W panel that would pair well in a 2p3s array with
A Growatt 3000 LVM
  • Max PV 2000W
  • Range Open Voltage 30~115VDC
  • Max Voc 145VDC
  • Max Solar Charge Current 80A
I was looking at Newpowa 210w panels
  • Voltage MPP Vmp(V): 16.77V
  • Current MPP Imp(A): 12.48A
  • Voltage Open Circuit Voc(V): 19.83V
  • Short Circuit Current Isc(A): 13.09A

If I understand the math on the panels
  • Total VOC: 3x19.83=59.49V
  • Total Isc: 2x13.09=26.18A
Does anyone have a better option (more watts)? I wont be able to get another panel but might be able to fit slightly larger ones on.

Thanks
 
If you have the real estate, I would over panel and run 3S3P. ~100v at ~25a. That is what I am running. 2250w max, but realistically closer to 1800w on a good day.
