Hi, Does anyone know the serial settings for the latest solar net from Fronius? I have 2 SYMO inverters I want to connect via RS422 but I need to use a serial/ethernet converter as they are some distance apart.

I imagine not too hard if you have experience in C++ and the TCP stack. It would take adding a layer of abstraction in the Comm class, allowing for different implementations (serial and network) based upon a command line option. The network version would need to work out connection management and implement readBytes() and writeBytes().

Hi David, Very useful project for working out how the rs422 stuff works. I have a rs422 to ethernet convertor attached to my invertor which works well. How easy is it to modify the code to talk to a tcp port rather than a serial device? Jeremy.

Thanks! That is nice to hear. Our home system has been collecting data every 5 minutes during the daytime, for the past eight years or so.

Many - many years later, I can confirm that fslurp works excellent in combination with the Fronius IG TL over RS422 in full-dublex mode. - I used a RS422 HAT (Shield) for my Pi 3B from HWHARDSOFT in Germany (https://www.hwhardsoft.de/2017/10/07/rs422-rs485-raspberry-pi-hat/) - The DATCOM setting on the Fronius inverter has been set to INTERFACE. - For some unknown reason, I had to reverse the A and B line. Kudo's for David, fslurp still works excellent after so many years after it's conception!

Yes. In fact it is not possible with flsurp - I had to create my own logger software based on LOGIG.exe.
