Hi Tim, I have only 1 PV per input, 2 PV per MPPT, that's 4 PV per Hyper. My panels are wired according to the manual. The panels are working fine for the last 2 years. I checked the DC voltage, and it's 40V per panel when the sun was shining today. The only difference today is that my batteries were fully charged which happened very rarely.
Thanks.
