I don't know how I can get those current amounts. I can get the amps output to the battery and I can get panel Isc. Not a clue if these numbers help any, but just now:
Panel Voc 34.2 (rated 36.8) Isc 8.31 rated 8.3
voltage at controller array terminals 28.2, at the panel connections 28.5. battery voltage 13.2 at controller and battery
controller in Bulk, 13.2v and 13.69a, showing 180w.(of 230)
I am trying to see on the IV curve where the power point was before tracking started and after but I can't make sense of it where in this case the voltage at the bottom is not batt voltage like with 12v panel IV curves.
