All solved by removing com between inverter & batteries, using voltages only and living the BMS of each battery does its job : stopping charging but equalizing cells when batteries are full.

Monitoring with Solar Assistant, all fine ...

      None what so ever, the BMS still takes care of charge and discharge, not the inverter. Just make sure the absorption voltage is set to the correct voltage according to the battery specs, set float vol

      100% and totally on the same page...  My batteries are 4 years old already... The first 3.5 years were controlled via voltage and the SOH when reading the BMS is sitting at 96%. I dont know why I

      I haven't read all the responses but nobody should ever run a Lithium battery pack without a BMS.  Deep discharge and overcharge can both cause a fire and would be trivial to have happen on a Lithium
