Victron Connect MPPT 75/10; term definitions

1..On History tab, Panel Yield equals what? The WH/D from the panel and not into the battery bank? So to estimate the WH/D going into the batteries, multiply it by .85 to reflect charging inefficiencies?


2. on History tab: how to convert WH/Day to AH/day which I relate to more easily? Divide WH/D by typical average charging voltage ~13.7V?


Thank you

1, this are the Wh charged into the battery no calculations needed.

2. Yes Wh divided by the voltage gets you the Ah.

1 is however the overall amount thats coming from the panel. So consumption through the Load out (direct use during day if applicable) plus whats going to the battery.

On my first question, I thought lead acid batteries lost about 15% of the input energy when going into the battery. Some call it charging inefficiency.

Thanks
