Fronius Symo Gen 24 plus Batteries

Hello Klangen82,

Thank you VERY much for your examples! I copied them and after some tweaking they work on my installation as designed (Full Charge / Full Discharge / Stop Activities).

What I still do not understand, after many hours of trial and error and checking many different forums, is why those numbers (60933 and 4603)?. All I found out is that they add up to the the value of 65536 which is Hex FFFF+1.

The reason I am asking is twofold:

  • I want to optimize my consumption from the grid and
  • I have 2 different inverters connected to a separate EVU. Hence I need to control the charge/discharge seamlessly and based on values from my EVU.

Now I am trying to setup a node-red automation, feeding the GEN24 10 Plus with the required values to keep the grid consumption at +/- 0.

The Fronius register map talks about +/- 1000 for the OutWRte and InWRte, but your values are much different. Am I right assuming (float setting assumed) that one number always need to be 65535 - the other value? Ideally I would want to keep the StorCtl_Mod always at 3?

Do you know where I can find more details on the topic?

Many thanks
Heinz
