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

BMV-712 SOC accuracy
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.
