BMV-712 State of Charge

Hi Everyone

I’ve a BMV-712 installed in our caravan which is fitted with a 100A/hr lithium. Using solar and DC-DC, as well as AC-DC charger. This morning the battery was sitting at 67%, charging ever so slowly on the solar. One minute later I noticed it had jumped to showing 100% SOC! I manually reset back to 67% but why would this occur and what can I do to ensure it won’t happen again?

Thanks Mark

the SOC will reset to 100% based on the Charged level setting plus tail current,

suspect your Charged level seeting is wrong on a 12 volt system change this to 14v
