Just got my solar setup going and want to make sure I am understanding things correctly.
I have 2 390w panels in series running to a Bluetti AC200MAX solar generator.
URECO solar panel specs:
Model - D7K390H8A
Pmax - 390w
VOC - 48.53v
ISC - 10.16a
Vmpp - 40.39v
Impp - 9.66a
The Bluetti charge controller shows input voltage of 91.0V and input power of 72W on this over cast day.
Panels are at a 23 degree angle due to being in MN. Temp is 25F outside.
Do I use the VOC or Vmpp rating to see the theoretical maximum volts the panels will generate?
Also, I have 780W of pannels yet its only producing 72W of input power?
Something doesn't seem right to me.
Any assistance is greatly appreciated.
Thank you.
