Yesterday evening I upgraded to version 2.17.39 (coming from 2.17.27) including the firmware.
First thing was, that after firmware upgrade I saw new names for the BMS CAN-Bus protocol in VenusOS. It is now “Batrium-BMS (Victron profile)”.
The first issue then was, that DCL was reported as 0.1A. And my MultiPlus 2 stopped inverting from battery. I could fix this by shortly editing remote control in Watchmon Toolkit and writing that back to Batrium.
The second issue arose when batteries became full today. CVL is for charging configured to 55.6V, a little bit more than 16 times 3.45V for balancing and within Limited I configured 54.2V. This discharged the battery a little bit, when Batrium reported Full and lower CVL but this stayed then stable at 54.2V, while DC coupled PV was fully feed in into grid by the MultiPlus. Today Batrium reported a CVL of 42.4V to Victron when battery is full. The MultiPlus enabled their full power to invert from DC, feed in everything they can, rapidly discharged batteries until a “Low battery” alarm appeared.
Why does Batrium report a CVL of 42.4V to Victron although I configured 54.2V???
