Greetings to everyone. I am having problems with a Voltronic Axpert 8Kw inverter, which measures a different battery voltage than the BMS. I performed the calibration procedure and it seemed to work, but as soon as it started discharging, the difference returned to -0.3V and sometimes even reaches -0.5V, meaning the inverter measures lower values than the BMS. Does anyone know how I can resolve this? Thank you so much to anyone who can help me.
