I´m using SmartShunt 500A/50mv for monitoring my consumption in my camper and the SOC of the LiFePo Battery. I use victron connect and VenusOS on Raspi.
As I see different values on my BMS App and VictronConnect specially with low current values my question is about accuray and resolution of SmartShunt values . What kind of AC/DC converter is used in the SmartShunt electronic? Some people speak about a resolution of 10mA but with a 16bit AC/DC converter only 15mA is possible or am I wrong?.
Voltage resolution of +/- 10mV @ 0.3% accuracy.
Current resolution of +/- 10mA @ 0.4% accuracy.
If I understand right with a real current f.e. 50mA with +/- 0,4% accuracy (500A) i could get a value between > -2A < +2A ?
No, "accuracy" here means "gain error" -- so +/-2A on 500A, +/-1A on 250A and so on. What happens with very small currents is "offset error" which is specced as <20mA.
