DESS: battery balancing does not reset after balancing

Yesterday my installation was to execute a battery balancing. This was visible in the VRM Portal by the “Battery balancing is scheduled for this day.”-message.

After reaching 100% (1 hour of adsorption) and several hours of floating, the DESS SOC setpoint kept on being 100%. Although DESS had other plans for the day, each hour the SOC setpoint for the next three hours was updated to 100%. Resulting in an idle installation at 100% SOC. In the evening the energy prices rose so DESS deciced to discharge anyway, prosponing the battery balancing to the next day. As expected, the same behaviour happened today: DESS keeps trying to balance the battery although adsortion and floating has been achieved for several hours.

What I did: I manually discharged the battery to a lower SOC and subsequently activated DESS again. Maybe another “adsorption to floating”-event would reset the DESS battery balancing attempt. But this didn’t work.

Two questions:

  • Are other users experiencing this as well?
  • Can someone at Victron reset the bit “Battery Balancing is due”?
