GlennWest Posted April 28 Report Share Posted April 28 (edited) Mine is showing 0 percent and is at 56.60 volts. Max is 57.6. Why isn't showing a percentage correctly? Now that it is fully charged it went to 100%. Edited April 28 by GlennWest Quote Link to comment Share on other sites More sharing options...
Chad Heiser Posted April 29 Report Share Posted April 29 It most likely has to do with the settings for the shunt. If the settings are incorrect, it won’t synchronize properly on a full charge and the state of charge will be wildly off over time. Less likely is the zero point calibration is off. If it accidentally got calibrated while a load (or charge) was present then all the readings will always be off because it’s zero point is off.

oldjohnt Posted April 29 Report Share Posted April 29 Glenn I have a different brand of shunt than yours, but I remember the initial set up WAS COMPLICATED I even had to read the directions over n over lol. Best I recall to set the shunts FULL Amp Hours indication to match my batteries energy storage capacity, I left the charger on a couple days then made sure there were no loads or chargers online. I must have done something right because its been over a year and the best I can tell my shunt is accurate from its 100% SOC read out at which time my charger and BMS shut down charging (quits drawing charge current or maybe a trickle maintenance) and I observe SOC slowly lower as loads are applied. I have no idea how yours is programed, but Id guess calibration and set up is the problem versus any hardware issues??? Call Victron and/or re read the directions I guess ????
