I have 6 Multiplus II 3000 connected to a Solaredge SE17K with frequency coupling.
Today we had several power grid outages and Victron went to Standalone Mode. After some minutes the Solaredge WR shut down and stopped producing.
One hour later (grid was back online since more than 40 minutes) the Solaredge went back online also. In the error log I found:
- AC-Frequenz zu hoch (Linie 1)
- AC-Frequenz zu hoch (Linie 2)
- AC-Frequenz zu hoch (Linie 3)
So it seems that there is an issue with frequency coupling. I am using the proposed setup from the victron handbook:
The solar converter will start reducing its output power at 50.2Hz
Output power will be reduced to a minimum when the frequency is 51.2Hz
The converter will disconnect when the frequency is higher than 51.5Hz
Can I make this setup more failure resistent with other figures ?
Any suggestions ?
