BMS charging current control limits are not being adhered to strictly, I see overshoots in the instantaneous current above the set point which is causing problems on our side. Average charging current is staying well below the charging current limit sent by the BMS.
This often happens on systems with no feedback enabled or no grid when a larger load drops off and the solar is going full tilt, there is nowhere for the excess energy production to go to (overshoot).
Sometimes running the batteries 0.1 or 0.2 v lower can help, or keeping a slightly lower SOC.
