Correct Firmware to use for Two Contactor Configuration


  • My current system design uses a two contactor configuration (separate charge and load buses).  I am running with firmware 2.6 on BMS hardware 2.1 .

    It looks like the recent firmware loads no longer support a two contactor configuration.  What is the latest firmware that I can install that still supports two contactors without depending on the "Tasks" feature in the new WiFi firmware?



  • In the 2.9.2 firmware update there is a file called bms_1A_Victron_v2_92_2_tasks.bin that should work for you.  If not, then using the Tasks configuration is the way to go
