Possible issue with number of inverters and system Ids

[jrbenito]

But I accidentally tested against an other situation so I believe that line 25 might not work as expected: raise ValueError("Error: need same number of inverters and system_ids"
The accident was that I had left commented out the address and port in the .conf file while i had set two systemid’s. I got no complain but only one system was uploaded, the first systemID. I tested with: systemID=12345,67890, systemID='12345','67890'. When using systemID='12345,67890' it was constantly restarting and not uploading

This was sent to me in a forum thread. Need to verify various combinations of systemID and inverter addresses in the config file. This was observed on multi-inv-rc3 tag.
