I have spent the better part of a month studying the Victron BMV 712 and how it functions.
There have been many people whom have experienced the “drift” in SOC reporting these little guys have over time and in a few cases there have been reports of large shifts in the SOC in a single day.
I believe I have determined the cause of these problems and come up with some settings that will improve the reliability of the BMV’s reporting.
This is especially important if you have a Larger capacity battery bank and charge via MPPT/Solar for extended periods of time.
Here is a 15min video laying out each setting with extreme detail.
Watching this video will hopefully help you understand what each setting means and better understand how your BMV works
