Providant139 says, “how do you recalibrate a Victron”??
First off, ask yourself why you’d need to recalibrate??…The only answer I can think of is that several years of battery usage has passed, thus causing some normal wear and tear (e.g. normal irreversible sulfation with age, or other battery malady), but not really needed as a routine exercise…
Or, perhaps your confusing recalibration with re-synchronizations which typically recur passively at the end of every full charge cycle?
Either way, to do a recalibration, you might simply impute a presumed amount of capacity loss over time (say x amp/hrs worth of decline, per season??), and adjust the meter’s programmed capacity accordingly, or do an actual load test which (without a solid reason…) many might view as an a love of unnecessary labor…
Bottom line here is that even with a small amount of naturally occurring capacity decline, I seriously doubt you’d find a need to routinely recalibrate when as an alternative (say over a x year period?) you might simply choose to go no lower than 55% SOC instead of your previous 50% SOC…Reality is that (for flooded wet cells), shunt meters are just not that persnickety - JMHO after years of meter usage…
