Sorry, I don't have charge controller output current.
I don't understand what you mean by "If you have cc input current, that would also look cool to see the difference..".
TPA Ahs and Whs are a direct reading and Hourly values are derived by subtracting each hour's ending reading from the prior hour's reading.
Vmp is derived by dividing Hourly Whs by Hourly Ahs.
e.g.,
15 136 25.301 741.7 4.317 123.2 28.54
16 130 28.29 825.5 2.989 83.8 28.04
At hour 16, Ahs = 2.989 = 28.29-25.301 and Vmp = 28.04 = round(83.8/2.989).
There are no moment in time readings because Watts into the CC depend on panel temp, Sun angle and insolation.
