Are you running the latest OS? I guess no one reads release notes.

a small change, but one that is good for everyone to know: after the upgrade, Multis and Quattros in a DVCC enabled BMS systems now report their state as External-control- instead of Bulk or Absorption. There is no bulk -> absorption -> float charge algorithm when controlled by BMS, and there never has been. This cosmetic adjustment more accurately displays what is actually happening with the battery charge profile when controlled by a BMS. This change will reduce questions like “Why does my system never go to float …is there something wron

@mk1 Your system is operating on 'External Control'.

Hi,

I also realized today, that "ext. control" is mentioned.

After reading many posts in this forum, I think I found the answer:

ESS - Multiplus status - VenusOS 2.92

"The status of a multi in an ESS has been external control for quite some time. It is the correct status as it is being controlled externally c/o DVCC."
