Absorption times

Hi was wondering if anyone can offer some advice.

I am not sure what absorption times to set on my system. Installed in caravan with daily consumption. System includes 2000va multiplus compact and 100/50 mppt, 3 X 120ah AGM Total 360ah. Need both mppt max absorption time and multiplus absorption times not sure what to set. Will use adaptive absorption for mppt but it there is still max time to set. Thanks in advance Niall.

@Niallp

The mppt uses adaptive charging, so not settable on the unit itself.

The multiplus can be set on the charger tab on ve config or under charger in victron connect. Usually set to the battery manufacturer recommended length of time.

Again if you leave it set to adaptive then the absorption time will vary according to how long the unit was in bulk charge.
