I use different batteries Li-ion 13S, 14S, 15S, whose BMS often doesn’t have communication with Cerbo. (Often, Chinese manufacturers’ BMS claim to support Victron, but in reality, this is not true). How can I make the Victron inverter display the SOC approximately correctly?
I know how to calculate based on voltages and the curve, but how can I provide it to the Victron inverter? Or how can I correctly set the voltage so that it shows approximately the same?
