Initially I had AC coupling mode enabled on my 18KPV to couple my existing AC inverters to it's Generator port input. This had been working until I added a GridBoss to manage my AC power distribution. Prior to the GridBoss addition, I had been able to monitor power using the monitoring connection through the monitoring app. Now with the GridBoss added, I'm not able to push AC inverter power back to either the grid or locally. I have tried all combinations of enabling AC coupling mode on both the 18KPV and the GridBoss. When I look at the physical generator connection at either the 18KPV or the GridBoss, there is no AC reference voltage at the generator terminals. I would like to have the 18KPV generator port support AC coupling mode since that's where my AC solar is connected to and it would be difficult to move this connection over to the GridBoss. In any case, I have also reviewed the following document (AC Coupling Guide for EG4 18kPV and 12kPV Hybrid Inverters) to make sure everything is configured properly. Both the 18KPV and GridBoss have the most current firmware - 18KPV - FAAB-2021, - 18/1/1, GridBoss - IAAB-1300. Again, this was working prior to GridBoss install.
