Good day,
I have an Axpert MKS II 5kW Inverter (Model Name - SMD LynX 5000-48) with Pylontech batteries controlled with ICC software (Version 4.9). System installed in 2019, running without issues up till last week sometime.
The ICC software picks up all communication from the Pylontech batteries, but has zero data exchange with the Inverter, everything reads 0.
There are no faults displayed on the Inverter. ICC show the following error log:
2022-03-09 13:38:08 The Operating System did not found the USB cable. Detach and Attach the USB Cable or Reboot the Raspberry Pi
I have swopped USB ports on the Pi. I have replaced the USB cable between the Pi and inverter. I have restarted the ICC and Pi several times and updated the ICC software. I have restarted the Inverter as well. No luck with these basic steps.
I suspect the Inverter comms card has some sort of failure. Any advise or experience with a similar issues?
If it is a comms card, where can I get spares?
