BMV-712 SOC accuracy

I have a 100/20 solar reg, 30amp victron charger and Bmv712, the 712 reads solar voltage and gives an inaccurate SOC. Is there anyway to get an accurate Soc

Your question has so little information its basically impossible to answer. The 712 does give a pretty good estimation of SOC. Most of the issues with it on here are incorrect wiring.

@Frankaus, if installed properly and configured correctly the BMV-712 is almost painfully accurate. That being said, if it is installed correctly it will be showing battery voltage, not solar voltage; if you're showing solar voltage then it's not installed correctly.

Please see the user manual for the correct installation and programming of the device.
