Solax X3 gen4 modbus read data

[madaraszko (Martin)]

Hi is here anybody who is using this config in openhab?

Solax Hybrid X1/X3 Inverter RealTime Data and control locally

Here is tutorial to complete control and read data from Solax Inverter X1/X3 (maybe others, but data can be wrong). It is connected directly to lan by RJ45 cable (No wifi required). Labels are in czech, but I hope, you can easily translate it. Don´t change settings frequently, because EEPROM of Solax has limited number of writings (I think 1 million) so 7 changes a day should be ok, do not use more. There is a lot more settings and data for your Solax available via modbus, but I didn’t put tha…

I have a problem with reading data from Solax X3 gen4 8kw.
In the log is error about modbus but Im not able to identify what is wrong.
Thanks

if you have correct ip and port, it is probably blocked by Solax Cloud. Try disconnect internet and restart Modbus binding

[madaraszko (Martin)]

If I try to telnet on this IP and port it’s opened. I have also serial to RS485 at home. Do you know how to change config to this connection?
Thanks for help.

[madaraszko (Martin)]

I’ve check firmware of the inverter and its 1.13 which is one year old and I have pocket wifi module 2.0. Is it working with this wifi module?
Thanks.
