My battery has been working perfectly for 6 months now with USE settings. I just realised that I've never seen an axpert with a bms port on the side like that, does the manual say it is for bms? What are the pinouts in the manual? Where did you get the cable you are using? I also run in USR mode, just posted to show what the BMS settings are when connected via comms. I use solar assistant connected to my battery

What are the pinouts in the manual? Where did you get the cable you are using? So I have decided to replace the inverter with a Lux SNA5000 ordered it this morning and then going to get everything re installed and setup. Apparently the Dyness battery talks perfectly with this inverter. I have had to disconnect the Dyness battery for the moment and I am back on my lead acid batteries. The installer tried everything to get Coms working but no luck. Even setup without coms with all the correct settings when the inverter is running off the grid every hour or two it would go to error code 8 (High Bus Voltage) and cut all power to the circuits the inverter was supplying to the house. Next week ill have the new inverter installed and lithium battery again and lets see how it goes.

To have an RS-485 port, it has to have a removable display, or the colour display with round LED ring.
