Node-RED Control PV Inverter Limit doesn't work on Fronius SYMO

Tried to limit PV Inverter to e.g. 3000 W via:

PV Inverter Control

This node is for setting information into the PV inverter.

Power limit (W), dbus path: /Ac/PowerLimit, type float

But it doesn't work as expected. I thought the PV production would be limited to 3000W, but it isn't. What are possible reasons?:

check the Fronius settings, Dynamic power reduction might be set to

No limit or set to use percentage instead of watts
