Could be because of bad usb a to usb b wire (use the original that came with inverter, I have still heard of them being bad) or like in my case, I somehow received two bad communication boards with both my inverters. I went back to my supplier ( Ian at Watts247) and told him my findings and explanation. Out of warranty, he still supplied me with new boards free of charge and I have not had any hiccups at all. I must say it took me a year to make it happen but..
My understanding is that the boards are not common to be bad or go bad, but in my case they had made several revisions from my original boards to the new ones. My opinion is that they all know this and are just reluctant to give them away.
My boards were bad right from the start, I could never get a stable connection to the shine server. Every other day I had to reset the thing manually (unplug the dongle, wait a few minutes, cross fingers, and do it again next day!). This is what got me on the Solar Assistant kick. After purchasing the RPi direct from Watts247, receiving it, plug-in, still no work. My thought was that it was plugged directly, it would work, but no. I had chased the issue far enough and was feed up. So that’s when I had one more go with Ian and thankfully he responded telling me Growatt had just sent him new boards and he would send them out for me to try…. It worked!
Hope my little story/rant helps you!
Mind you this is just the short of the story and is not me trying to bash on Ian or Growatt, sometimes thing happen out of our control and some the length of time is partially me procrastinating and being Pee’d off.
