JK Inverter BMS communication with the Sunmart VMIV inverter is not working.

[roli32]

Hello!

I have a JK-PB2A16S20P (JK Inverter BMS) and I can't establish communication with my inverter. The inverter is a Sunmart VMIV 5.6KW.

Neither CAN, RS232, nor RS485 is working.

I can read data from the BMS via RS485 communication with a PC, but not to the inverter.

Any ideas?

What cable are you using? What uart1 protocol did you use in bms and what sort of battery did you choose in inverter?
