victron shunt battery monitor, reset at what voltage ?

[simonfraser]

on the app you can program it to reset the battery capacity to 100% once it senses a certain voltage
by the looks of the manual this voltage is 'the charged voltage parameter'

ha, at what voltage is my '12V' lead acid battery full ?
the manual suggests 13.2
but my solar charge controller cuts out at a significantly higher voltage, which to me seems the better 'full' voltage

so what to set the victron to ?

*I think* to where the mppt has it's max setting (should be the same as the main charger btw).
*I think* you put the absorption V not the float that comes after and is lower.
curious to see where mine is setup, will check tomorrow and report back

V.

My solar controller does a 30 min ‘desulphation’ at 14.3V once a day
have set the ‘full’ voltage at 14.2V

At what state ? a standard FLA battery on charge is around 15.4 volt, rested off load 12.7 to 13.1 volt, varies with battery age, battery temp and other things.

Your best bet is to set it at max charge voltage, less a little bit for safety, may not be full, but the best you will get.

In passing you can get a battery up to 100% with a transformer based charger, hard with a switched mode.
