This is driving me crazy , i cant seem to get my friends older style BMV-700 shunt to show the batteries charging , when discharging its fine and slowly showing a decrease on battery capacity but just after the input from the Solar panels start go from negative to positive current flow the shunt jumps from around 63% to 100% . In settings it theres a toggle to go to 100% on Reset , tried the toggle both on and off , makes no difference . . My own Shunts are Smart shunts and run direct to Cerbo , my friend doesnt have one so i had to connect a VE to USB cable from the back of the round display .
Would be very grateful if someone could explain what im missing
