Hi, I am setting up a Waveshare RS485 to Modbus adapter to connect my KH10 inverter to Home Assistant. The inverter is not installed yet - fingers crossed, it will be by next Tuesday - so I can't test anything but I have read as much as I can about the process. My main questions at the moment are about configuring the Waveshare device. I am trying to follow Nathan Marlor's very helpful wiki on Github, https://github.com/nathanmarlor/foxess_ ... TH-%28B%29 but I am confused about what baud rate to set. I have seen several quoted values, 9600, 19200, etc so my questions are:
Can you set the RS485 baud rate in the KH10 inverter and if yes, then how to do this?
If the KH10 has a fixed baud rate what is it?
Thank you in advance and also apologies in advance as I just know there will be loads more questions as I try and get HA to work with my setup.
Regards, Hugh

You can’t set the inverters baud rate it is fixed, the waveshare should be set to 9600, N, 8, 1
See here for full settings https://github.com/nathanmarlor/foxess ... TH-%28B%29 approx half way down the page it says Now, copy these settings (obviously ignore the IP address that should be yours)

Thanks for that. 9600 baud it is. Or will be, scaffolding for panel installation put up today so getting close!
