Sungrow sh5k-20 Connection refused

[red-barran]

Hi everyone,

Thanks very much to meltaxa for putting this code together!

I'm attempting to get data from my sh5k-20 and upload it to PVOutput so I can have a consolidated view in conjunction with a second inverter. I want to make use of PVOutput parent and child function (activated with a donation). I have about 7 years of data up there from an older Samil inverter with a Smappee device

I have had some difficulties with this code. I'm using the Docker option and seem to have it trying to connect to the inverter's IP address on my home network. I am getting this:
ERROR:pymodbus.client.sync:Connection to (192.168.1.35, 502) failed: [Errno 111] Connection refused

Also, with the Python option, I have a new install of version 3.9, when running the requirements.txt, it will not install SungrowModbusTcpClient. I changed the requirements to use pycryptodome rather than pycrypto as this seems to be depricated. I can install pycryptodome but for some reason I am unable to work out, when SungrowModbusTcpClient tries to install it it still looking for pycrypto and fails. This is why I went over to the docker option.

Thanks!
