My OverKill Solar showed lower SOC vs. Victron Smart Shunt. So I change the OverKill Solar SOC settings to better match the charts here.I've been watching my battery bank voltage along with my battery monitor kit which seems to be a good judge of +/- AH. I reset my AH meter at full charge yesterday and now my 345 AH bank is down 110AH and showing 46.0V (my 14S configuration is fully charged at 51.0V). According to the voltage chart on the first page, I am at approx 3.285V per cell which is right around 60% SOC.
I understand the SOC % is not going to be nearly as accurate as a shunt reading, but it seems to be in the close ballpark.
