I don't believe you need the terminating resistors.
Have you tried swapping the wires? On RS485 A goes to A and B goes to B. Although it's a bit confusing as the User Manual implies A-B & B-A.
You need a Baud of 9600.
Edit: If you have working coms but your Inverter isn't supported yet, you will get your Serial Number printed into that log.
Did you have another look at your wiring?
Closing down as no response. If you are still having issues connecting then raise a discussion topic.
Sorry wills106,
I had A small vacation so wasn't able te response.
Yes I had check the wires. and the connection is OK. Swap the USB dongle, for the A new one, but dint mace any difference. The resistors of 120K removed, no difference.
on tweekers.net dev5000 got it to work. also make A request for his solution, (sorry forum is in Dutch)
When and if I get A response from dev5000. ill let you know.
Inverter: solax x3-pro-25k-g2 RS485 usb to home-assistant: Amazon link SolaX Inverter Modbus: 2023-08-06
From the inverter RS485 bus: A(data+) > home-assistant USB: B(data-) From the inverter RS485 bus: B(data-) > home-assistant USB: A(data+) On both sides are resistors connected with A value of 120K
I do not get any data.
Also there is no modbus list from solax, I've sent an email and the repay was it's not released. only true the web API.
