Discover why your Victron SmartShunt shows 0% SOC despite a battery voltage of 13.2V.
0% SOC indicates that the battery is considered fully discharged. This can occur due to calibration issues or incorrect settings.
Check the battery connections and ensure the SmartShunt is properly calibrated. Also, verify the battery's actual state of charge.
The SmartShunt calculates SOC based on current flow into and out of the battery. A 0% SOC reading while the voltage indicates a charged state suggests a disconnect between current measurement and voltage sensing. This discrepancy could be due to faulty shunt connections or a miscalibrated SOC. The inverter may trigger this fault if it detects an anomaly in the current flow, which can occur if the shunt is not properly wired or if there is insufficient load on the system.
The Victron SmartShunt displays a 0% state of charge (SOC) on the monitoring app, despite the battery voltage reading 13.2V. The LED indicator may show a steady green light, but the app provides no alerts or additional fault codes. Users may notice that the system is not drawing power from the battery as expected, leading to operational issues.
Always consult a licensed electrician or certified solar installer when troubleshooting electrical systems to ensure safety and compliance with local codes.
To avoid this issue in the future, regularly inspect and maintain all wiring and connections associated with the SmartShunt. Ensure proper calibration of the SOC after any battery replacement or system modifications. Keep the Victron app updated to the latest version to benefit from improvements and bug fixes. Schedule periodic checks of the BMS to ensure compatibility and functionality.
