Read data out of SMA sunnyBoy #61

Open rogierlommers opened 4 years ago

rogierlommers commented 4 years ago

Hey, maybe a bit stupid question, but do you think it's possible to use this package to read data out of my sunnyboy inverter? According to the website it supports modbus. I also opened port 502 and by using netcat I indeed see some response on that port. But then what? What is my next approach in finding out what "registers" I should read to get the current generated solar energy?

i'm doing it. what model inverter? you need to find the right modbus map for your inverter. They are not consistent across models.

I am using telegraf, which uses this project for modbus protocol support.

Thanks for your reply; I want to read a SMA Sunnyboy, model "Sunny Boy 3.6 1AV-41". Any idea how to proceed with this?
