Good day
We have a site with a Fronius symo connected to the output of 3 x Multiplus II and set to no feed-in. There is an external energy meter connected at the property mains supply.
The system still currently feeds-in the excess from the Fronius to the grid. Is this a setting issue from the Victron site or the Fronius? Or is the issue something else entirely?
Do you have configured the Fronius for Zero-Feedin?
What does the Fronius report for Zero feed-in Power Limit, when this happens?
I’ve noted, that (for my system) just disabling “AC-Feedin” didn’t result in the expected behaviour,
I had to enable AC-Feedin, but set a limit of 0 Watt in order to have the Fronius beeing throttled:
Also ensure, under settings → services that Modbus TCP is enabled.
