Just to clarify my setup:
My inverter is connected to two batteries. I have one of those garden switches that lets me press a button to program days it'll let power through or turn it off along with a manual on and off button. My idea was to have enough power needs at full charge for 2 weeks when outages regularly occur during winters and summers in my area. Otherwise my power draw is low enough where running a few laptops to last about two weeks before needing a full recharge. Each time I fully recharge the battery to 57.60v with a float value of 55.20v. I am in an apartment so am not able to connect to solar yet.
@HighTechLab I keep shore power off at the moment so I just use the battery until it gets to about 50% (which I've now realized isn't the case) and then I'd turn on shore power to recharge to full. Anyway I can change the sleep mode setting? Otherwise I'll make sure to just recharge to full each week so the SOC and BMS are functioning. I have shore power coming from an outlet that lets me set what days each week shore is on.
I estimated it'd take me 2 weeks to get down to 50% for my normal usage when we aren't in an outage. Prior to having my Smart Shunt I would turn the inverter off through the Victron app when my work day was done and then back on when I began work as a way to save a bit of power from the inverter drawing. Could that have effected my SOC?
@740GLE Correct, Victron registers it a low battery, which I now have learned is 50v. So like HighTechLab pointed out, something is drifting with the SOC.
