Doesn't set Feed-in limiting active

Hi Victron community!

I try to set ESS with Venus GX, Multiplus II 48/5000 and Fronius Primo 5.0-1.

I made the settings described in the documentation, but Feed-in limiting active shows No.


If switch on "Data export via modbus - tcp" in Fronius that in remote console in Fronius / Device/ Connection solarapi changed to sunspec and appeared string"Zero feed-in power limit 5000W".

So I guess that Venus GX connected with Fronius via Modbus.

And I noticed when in Fronius switch on "Inverter control via Modbus" than in remote console in Fronius/ Status changed from "Running (MPPT)" to "Running (Throttled)".

But in any case, Feed-in limiting active is No.

What could be the matter?

Hi (sorry can't tag your name)

How much is actual feed-in to the grid? is it limited to 1000W as you set the limit to?

Our regulations prohibit feed-in. I made 1000 watts, for example, to see if this setting affects to set Feed-in limiting active in Yes. It doesn't matter what the limit is. I have not connected the multiplus to the grid while the ESS will not work.


Could you please explain to me what conditions must be met for Feed-in limiting active to switch to Yes?

make sure the Fronius is set to sunspec:

I have checked, the Fronius is set to sunspec: int+SF.

In remote console there is string

Does it make sense to update a firmware of the MultiPlus from 459 to 481?
