DIY

Hello!

I was not able to find the exact in sufficent detail - so bear with me please..

I use a Fronius Symo with Datamanager and want to AC couple a Multiplus 2. The Fronius has the energy meter installed and I get the data from IP network if required.

Do I still need a Victron meter (like the EM540) or can the Multiplus 2 use only the Fronius meter? The Victron manual I found do not talk about that resp. rather that is not possible (which is a bit counter to comments I read here).

Thanks for advice!

Not officially supported, but it works! I ran it on Venus OS on Raspberry, and it worked perfectly! Should also work on Cerbo GX.

I had to modify the run file after downloading it from GitHub, but unfortunately I don’t remember what I had to change. It had something to do with the Python version.

However, I have since switched to EM540 now, as it makes the control system work faster.

Found it, I discussed it here:

I had to modify the entry in the run file as follows:

#!/bin/sh
python /data/dbus-fronius-smartmeter/dbus-fronius-smartmeter.py

Danke - soweit hatte ich nicht zurück gesucht.

Ich nehme an das geht auch wenn man nur den MP2 GX hat? Man spart sich den Smart Meter mit dem Einbau und hat dafür mehr Einrichtungsaufwand - und vielleicht die etwas langsamere Nachregelung?!?
