Thank you for the link, I am working on it right now, I will test it through fully before putting the code here
Testing takes some time, as with a tac1100 on my desk i can only read volts and Hz, but i will put it in my solar system, import export all will be tested

thank you for your cooperation

I just compared the modbus protocol of the easton sm120 with the tac1100 , the first 6 register addresses are the same the other 20 parameter addresses are completely different, those 20 other parameters are important for solar installations. Send me the source code of the easton plugin, and i will ...

My issue with the wifi part, is i have to manually reset it every few days as it suddenly not respond anymore. no power supply issues with the esp nor router. also not after a certain time it stops, i have no clue yet @mr alt, the extracted data i send as a string to the esp, as the 5v environment i...

The above code I'm using to actively adjust the power factor settings for my solar inverters. as they accept settings between 0.80 and 1.20. When there is no sun, or not enough, the power factor is adjusted by switching capacitors every 10 min. :) this all with just a nano... When my ESP 32 version ...

i've put the download link in the first line of my comment, but in case the link will be removed in the future, see few post earlier,I dumped the whole pdf in the comment so the info is always available for everyone in the future. Soon i will put a small working arduino sketch, as I'm busy with test...
