Raspberry Pi and Growatt inverter

Anyone got a working program to monitor a growatt inverter via usb or wifi on the raspberry pi please? Python to complicated for me :slight_smile:

You need usb to RS485 (or RS232) and python but its not that hard.
For monitoring with pvoutput: https://github.com/jrbenito/canadianSolar-pvoutput
Though if using python3, you will need to modify the code (where print command does not include brackets)
For local monitoring: https://github.com/ZeroErrors/solarmon

I’ve been using the above for nearly two years now and it works well. There is a thread about it here Help Required Uploading Growatt Inverter To PVOutput


I have tried to follow this tutorial: https://fixedbycode.blogspot.com/2014/04/how-to-upload-data-from-growatt.html

But i am not able to get all the packages needed for python. I think the commands are to old.
If someone has a working image for raspberry pi version b or never, i would really like to get a image file.
it must be the easiest way if i only have to change the api and user name for pvoutput.org
Any help in getting a raspberry pi working for uploading growatt data to pvoutput would be very much appreciated.

Thanks in advance
