It happened now two times that batteries switched off - on their own!
.
The first time was when I updated the BMS of all batteries to v1022,14,
drained them to 0% and following, charged them to 100%.
Then, my adjustment over night was: charging from grid OFF, AC OFF.
Next morning I noticed that one of the batteries was switched off.
.
The second time at the beginning of the night the overall SOC was ca. 45%.
During the night the adjustment was the same: grid OFF, AC OFF.
The following morning I found five of six batteries switched off!
.
What is going on?
A bug in the new BMS version?
