hope you can get me some hints regarding the setup between BYD B-BOX (L3.5) BMS and Victron Multiplus II GX (3000er), which I bought new.
I recently bought the BYD B-BOX battery used from another user who had it running with a Victron Multiplus but now switched to PylonTech.
My setup is as following: MPPT SmartSolar DC connected to battery (short test: charging works, as indicated by the BYD battery (low rate white LED flash and battery voltages are in a reasonable range) and Multiplus GX connected to the battery.
Actually, I not have AC-IN connected to the grid nor the EM24 (my electrician will do that next week). Connection with SmartSolar via the VE.Bus worked very nicely. Also I follwoed the video instruction of Guy to setup the Victron for first Multiplus setup (setting to 500kBaud, DVCC, etc). I used a Typ A cable for the CAN between BMS and VE.CAN. I have an end plug / resistor on the VE.CAN as well.
Status message after reboot the Multiplus is: Not connected. In the BMS-CAN port i found following error message: Error-passive TEC:0 REC:128. Some Multiplus continues pushing packets. See the screen shot below:
Do you have any hints which root cause the error message may have?
Thanks for your support!
