good morning everyone, do you know why there is this difference in the display of solar production? The mppt indicates 6.6a, but the same device via VRM indicates 3.5a?? 
VRM shows current at panel voltage
MPPT shows current at battery voltage
Well that’s as mine is.

Yes, and I think that makes sence. The battery voltage is visible, when looking at the battery, so displaying battery voltage for the mppt is not giving much information.
And when you then display PV Voltage, you should also display PV current, so it matches calculation of Outputpower.
