I've seen other responses to this question that did not help me solve this - like, read the manual. I did, followed the setup, and I am still stymied. I have a 960W PV, Quattro 5K, 2 100/50 MPPTs, 3 200Ah Smart Lithium Batteries, and the BMV712. It's all brand new and works perfectly except for this one thing. After night time discharge down to ~60%, normal charging seems to occur throughout the day. But, in watching the BMV (and looking at history on VRM, it jumps from ~75% to 100% SOC, and then continues to consume 600+ watts of solar for several hours. I've tried the manual zero current calibration, and once I saw current drop and and trickle into the batteries mid-afternoon (assuming it was close to 100%), tried to manually sync the SOC. But, it continues to do this even after. What am I missing? Any help would be appreciated.
