December 19, 20223 yr Hi So I have 2 setups 1: Synapse 7.2M+ (Axpert Max) with 2 x CFE 5100s batteries 2. Kodak 10KW (Axpert Max II) with 2 x CFE 5100s batteries So has anyone managed to get the BMS communication with these inverters ? I had CFE Tech update the firmware on (1.) - after which the inverter does connect to the battery BMS - but seems to lose connection at some point (Warning 60) and other erratic errors - when setting manual parameters and removing the bms cable - no errors or warnings - and everything works I have not had them update the second pair's firmware as I see no point at this stage so running manual settings atm. Anybody has any advice ?

January 30, 20233 yr I'll keep at it with the Guys from CFE from my side... I have a stable system in the wild using the LuxPower with the CFE (2 Months now). I also want to use 2x CFE with a Kodak 7.2 Max (Axpert Max) and see what I can find. Do you know what firmware the Synapse 7.2M+ (Axpert Max) is running?

Do you know what firmware the Synapse 7.2M+ (Axpert Max) is running? 45.07 and panel firmware 12.13 - also see my DM reply Edited January 31, 20233 yr by Rosh
February 6, 20233 yr Has anyone had success yet? I am looking to connect a CFE5100s to my axpert king mk ii. There's little to no information on how (Using the BMS) though. I know a firmware update or change may be needed but not sure who to contact for this.

February 18, 20233 yr What is your USE setting on kode inverter for Charge and floating voltages? If I go over 54v, my cfe goes into fault mode. On CFE specs it states 57,6v.
February 18, 20233 yr Author Make sure the CFE batteries are on default dip switch settings only the master slave dip switch set. 53.8 is bulk charge/cv voltage, 53.6 is float and cut off voltage at 48V
