Main Grid Failure Alert when Inverting

Can someone tell me why I get a Main Grid Failure Alarm when the Multi goes back and forth from an 'Ignore AC' condition.

Periodically, when the Multi is inverting (but connected to grid) and dedicated AC Ignore is selected in VS tab I get a Grid Failure Alarm. But the grid hasn't failed and VS functions properly, switching between Inverting and passing through Grid AC when conditions are met. In VRM portal dashboard system overview, the Grid box will show ' - ' when inverting, which I figure is normal since it's not drawing any current, but it's odd I keep getting a Grid Failure alarm. Is this the Multi's current sensor mis-reading things or is there a setting I missed somewhere? Thanks!

Because you are disconnecting from grid with ignore ac. So technically the connection is lost. It is really a warning to let youknow you are inverting again.

Check on your GX device you can enable or disable it there.

Menu - settings - system setup - monitor for grid faliure.

@Alexandra I found that, but if I disable that in the GX device, will it disable automatically switching to Inverter mode when there is a mains loss? Otherwise, what's causing it, any ideas?

No it does not change any settings or functions just the alert warning

@Alexandra So, I disabled it, no more alerts, but I still see a slew of these in the logs, should I just ignore, and what do you think causes these?

You can reboot the GX if you want to clear them.

They stay there until you do, log them to the VRM as well.
