Limitation to AC coupling with EG4 18K, help required...

Are you saying the EG4 18 Kpv is in off grid mode at the time of the picture?
 
I believe, Millsan1 had a Growatt AC coupled to his 18Kpv is that what you are referring to?
 
I apologize for my untimely replies, it seems I'm not getting notifications when folks replied to me including EG4. So I have to monitor this forum more often and not rely on notifications.
So the post entry that I saw yesterday from @millsan did not mention another inverter in parallel other than 18k.
I just looked at the post from EG4 (thanks to BKY2003) and I wish that I had seem that in a timely basis, maybe they could have helped.
The folks at SS are very nice but I get different answers, depending on I've talked to. I pointed out that a couple of months back I saw a video from their marketing manager "Kelly" that stated that this was possible but still they told me that it was a known issue and opened a ticket for which I never heard back.
I have AC coupling working but in off-grid mode. I have time today so I will spend some time with them, maybe I get lucky the third time around.
I'll post back after today's session and let you all know where I stand.

Thanks again for the willingness to help me and I promise to actively check this thread avery couple of hours until I can resolve my notification issue.
 
Well I spent ALL day with SS and after many issues with the crapy DONGLE they changed some settings (from the prior tech) and it was my lucky day with them, it started working on-grid "kinda".... While it is using the AC coupled solar panels and selling unused power back to grid, it has a relay that keeps tripping on-off every 4 seconds while the green "Normal" light goes on and off.
They are escalating to their experts for resolution. I'll give them the courtesy of finding a solution before I get EG4 in the loop. For now I disabled the AC/C as that seems to stop the relay loop.
I will update this post as go along with this issue, in case someone else gets unlucky with the same setup.
