SOC/battery voltage desynchronization problem

Q&A and troubleshooting

  1. You have not correctly installed it and have an unmeasured drain. See Shunt / battery monitor not reading the correct SOC/ Amps, missing solar, decreasing daily or other misreading problems
  2. You are not synchronising correctly, see Battery monitor jumping to 100% or reporting a high SOC with low Volts / the BMS shuts down
  3. Your settings are for lead acid and are not suitable for lithium, post screenshots of your settings.
  4. Very unlikely, but you have a zero calibration error. Procedure in the manual to reset this, needs everything disconnected. This is a very rare thing so do 1 to 3 first.
