Outback used to have a string sizing tool online but instead of hosting it they changed it to a download that I can't get to work...so...
My panels are 54.7V and 5.98 amps. The 3 Flexmax 80 charge controllers have a max input voltage of 150VDC.
Question 1) does this mean that I can wire in series a max of two panels in a string then have to start wiring the strings in parallel? Two panels would be 110 VDC
The current layout has 10 panels at 110 degree Azimuth/14 pitch, 18 panels at 110degree/27 degree pitch and 12 panels at 290 degrees/27 degree pitch.
Question 2) should the panels be split into three groups and each fed to a separate charge controller? Or do the charge controllers get bunched together and you just feed them all? Given my different azimuths I won't have full production from all panels at the same time. So although I'm over panelled I shouldn't be load clipping.
Question 3) If I mix two panels from the flatter East group with the 12 West facing panels how much will that degrade my efficiency? (the reason I would allocate 14 panels to this charge controller is that they will produce less than the East facing ones)
Question 4) The difference in production from the 14 degree pitch to the 27 degree seems likely to be 10%. How bad would it be to mix these?
As always thanks and pardon my newbieness!
