Suspect this has been covered but can't find.
My75/10 mppt takes from 100w panel to 12v AGM battery. Settings appear to be OK. Charging voltage around 13.5 then goes to float at 13.8
Don't I need 14.1 to charge?

Charging voltage
Check your settings using Victron Connect app under battery to make eure they are 14.4 absorption. The other thing, when is your absorption at 13.5V, for the whole period of absorption. If the sun is not bright then you may not have enough power to get to 14.4V. Also if you are using a lot of your battery, try setting a longer absorption period or ending absorption on tail current if you do jot have a lot of loads running while charging.
Thanks. Absorption is set to 14.7
Using my meter I just never see above 13.8 on battery.
The panel voltage is well above
19 or 20v or so
