Yes, tried it with AFCI off and on, no difference unfortunately.

No, the control firmware did not load.
Do it again, I’ve had to do it twice before to get it all updated. Might also look at your stick and make sure the control firmware files are there and the text file that tells it what to load has it listed
I tried it again and left it in longer to make sure it finished, but same result. These are the files that were in the zip folder from Growatt support. Is anything missing?

Yes, inverter is showing as on in the quick settings menu. I don't have a battery connected to mine, don't know if that requires any settings turned off that I might have on perhaps?
I don't have a battery connected to mine either so they should not be a problem.
Have you ever tried it on a non snow day or is today the first attempt?
We powered it on Thursday, no snow then, and even now almost all the snow is off the panels. Whenever I turn the DC disconnect to the on position the voltage coming from the panels drops to zero. The electricians saw that too and said the Growatt inverter is doing something to stop it, and they thought it must be something in the settings.

Please send Screen shot of the text file contents. Sorry for delay, just finished splitting a beehive that was ready to swarm…….

Until your control firmware is correct there’s not much point in worry about anything else I believe. Need see content of text file and compare to mine

Something just occurred to me when looking at your picture, do you have continuity between your green ground wire and any of the PV positive or negative wires with the inverter disconnect open? You should not. But regardless, the control firmware is a problem.
Also, I see you don’t have a power meter. By default I believe the inverter output is set to zero and a power meter is enabled, might check that also. But still, the control firmware is a problem.
Here is what's in the text file

In this picture the red arrow is pointing at it. If you don’t have a rapid shut down button connected there the inverter comes with a jumper to put in place. Or maybe it was already in place from factory, not sure as the electricians installed it all.

It’s installed at the factory. I removed mine on one inverter and installed the trip button to test it. Then put the jumper back. The inverter would “trip” periodically when I was working in the basement, I eventually figured out I did not get the jumper all the way into one of the terminals and it was vibrating occasionally. Kicked my ass for more than 3 months in 2022.

That is same as mine except for the battery which you don’t have. Are there files on your stick that match the file names in the text file? EDIT: never mind, I see in other screenshot the files are there and properly named.

Looking through threads, seems like this Guy had the same problem. Have you tried this?
"I found maybe some way to wake up, I change in the app Shinetools connected direct to the inverter
go to Grid Code -> Synchornization Range -> Connection Time and Reconnection time change fro 300 to 301, apply the Settings (blue bottom)
and done, after wait 301 seconds pass from Standby to On Grid
I not sure why, but in theory 300 seconds is a normal waiting time for safe connection to the grid
I hope this solves your problem"

Also, completely power off the inverter after firmware upgrade and let it restart. Not sure it will do any good but was told to do that one time. Can’t hurt to go ahead if you have not already
Thanks! I just looked and mine has that jumper in place as well.
I did notice on the multimeter it showed -538v. Would that mean the polarity was reversed? I wasn’t sure if the - was just a dash it showed
