At present I can't measure above 5 amps DC and I realy have doubts about the spread sheets estimate. The volt drops were correct but the current seems high like maybe their controller estimate is for mppt not pwm.
I'll have a better idea once installation is complete.
I am very interested in seeing your observations. TY for posting
