Fronius Hybrid with Modbus TCP

[Tico]

You might need to clarify what you mean by the target value at the metering point?

Are you referring to the power value you wish to export to the grid? The Dynamic Power Reduction feature provides a set-point of desired grid-outflow. The inverter will modulate it's output to satisfy the household requirements, then attempt to achieve the desired grid-feed.

No, I mean the target value at the metering point.
Thanks

Google Translate says -

Gast - How can I access the target size at the metering point via Modbus?

I can't find a register for that.

I assume you mean the minimum battery reserve (paragraph 3 in the index)?

Wie kann ich über Modbus auf die Zielgröße am Zählpunkt zugreifen?
Dazu finde ich keinen Register.

Hi there

I have a system with 2 pcs. Sym Gen24, each with its own Byd battery pack, and 1 pc. Symo 20. We have just started the system and are going to connect it to Loxone. We have some challenges with getting the right data from both inverter and Smartmeter, I have been on fronius website to find the modbus tables but without success. Have you had any challenges with your connection to Gen24 and the batteries.

For info, the Vendor Operating Codes are as follows (from a question raised earlier in the thread) -



The State Value is set to 0 for regularly occuring (normal operating) status. The Filtered Error codes are passed onto the AIe input of the Loxone Energy Monitor.

The StVnd value is the operating State of the fronius Symo. What does the value 3 tell us? And which values are possible for StVnd and where can i see the possible values?

[Tico]

Sorry, but I don't understand the question?

[19domi89]

Where can i see, which operating states are available in the documentation? Thanks

i have one other problem
on Pp i have connected my actual production (AC_Power) but on AQp is notting shown, also not on the visualisation.

[renezs]

at time i have some values from the inverter. But maybe not the right.
The modbus device adress for the smart meter youn can choose over the webpage of the inverter. The preset her was 200.

[Tico]

One difference I did read with the new smart meter is the Modbus device address -

Fronius Smart Meter 63A-3 has factory value 240.
Fronius Smart Meter TS 65A-3 has factory value 1.

Thanks,

this is what i have find too :-).
I have sent the questions to fronius. Let's see what's the answer.

Ok, you might need to contact Fronius direct. As the first user here of the Gen24, congrats! It will be interesting to find out how much more responsive it is than the Hybrid.

I found the following details in the TS 65A-3 instruction manual regarding firmware. Not much help unfortunately.
