Hi,
I noticed since a few days that the charge logic is not being followed sometimes when the systems is in "Keep batteries charged" mode. See below charts
DVCC is on and the bms is sending the correct charge voltages.
The pack itself is perfectly balanced within a few millivolts.
It happens when there is a peak in solar production, altough everything is connected on the AC side. (No DC MPPT's and DC system is turned off). I would expect that the grid feed-in would just increase instead of overcharging the batteries.
Is there any explanation or setting that I missed?
Thanx,
Bjorn
