SMA Sunny Boy stops working when grid connection is lost.

Hello, I have an ESS system with Victron. Recently I installed a 2017 Sunny Boy SMA 3000 with 3600Wp of solar panels. I have the assistance for frequency shifting installed. And set the grid code to offgrid 50 in the SMA. In the VRM, the SMA inverter is visuable. Everything works. Exept when the grid connection is lost, the SMA inverter stops inverting. The SMA inverter is connected to AC out. What settings did I miss?


Thanks!

It's normal that the SMA shuts down at the moment of grid lost (and while the ESS is synchronizing to the grid) but it should (try to) restart after a few minutes.

This is euh.. Nice. After 1 minute it restarts. Why didn't I wait a bit longer. Thank you so much!
