I’ve been experiencing a phenomenon for a few days where the SOC (State of Charge) suddenly jumps back to 100% at night. I can’t really identify what’s causing this. I’ve checked all the connections of the block modules. What can I do to isolate the problem? My system had been running smoothly for about 4 years before this.
No one has any idea?
Hello @Breakyman , as discussed elsewhere, I only know of two situations where SOC is reset to 100%:
- in Hardware > Shunt settings you enter the capacity of the pack. There you also see the first Recalibrate SOC-reset setting. Once your charge flows over 101,5%, SOC will be reset to 100%
- final SOC calibration is done based on minimal Bypass value/session for all cells under Control-Logic > Charging. This means ALL cells need to reach a certain bypass value before SOC is reset to 100%. Actual bypass voltage is found in Hardware>Cellmon. This means, if you have one misbehaving cell (or bad connection), you will never enter the Bypass Complete phase. Monitoring of the bypass value per cell is found under Telemetry>Cell-Info
I must admit your situation seems to be different.
