Cerbo GX - Change AC Pos dynamically

Node-RED

Hi,

is it possible to change the AC pos of Fronius devices dynamically with node red or a custom service? I have a setup where i can change the inverters position and would like to switch them between AC IN and AC OUT based on yield and consumption..

Hello, I have found a way in theory on Node-Red, but it does not seem to actually implement the change in the Cerbo and on VRM, although Node-Red shows no errors and it flows correctly with confirmations
.
It works like this:

  • Quattro inverter Grid status is the first trigger
  • If grid is ON then it proceeds to “Change” module which has the msg.payload to “1” to set the position to AC Output
  • This then links to the “PV Inverter Control” which selects the specific inverter and “position” as the Measurement to adjust.

It seems to flow in Node-Red fine, but in actual it never changes it in the Cerbo.

Please see below/attached the photos which I also included the status identifier next to the end of the flow which also shows how the change is not implemented. Not sure if anyone else has any ideas?
