Continuing my never ending quest to trying to understand boat electrics.
My set up 4 x 110 open batteries new last May + 1 x starter 2yrs old, 1 x alt, the standard one on a Vetus 415 (90amp?), Adverc controller and i think that is it as far as charging from the alternator is concerned. I do have solar and also a Victron charger but guess that doesn't come into play until on mains, which is never.
I often read about various charging volts, boost, float, etc and volts rising up to 14.8 at the start of the charge and dropping to 13.9 on float but what i find confusing is i have yet to see my wired in volt meter record anything under 14.4.
Even in summer when we set off mid afternoon with full batteries from the solar the meter shows 14.4. This time of year they will start charging at 14.8 and drop gradually to 14.4 but no lower. Is this to do with the Adverc and does it seem normal or does something need tweaking. Batteries seem fine and holding charge. Just curious really.
