CCGX & Fronius Symo - Connected Unknown

Hey there!

I got a 3P Multiplus 48/5000 installation running, with 10kw Solar and ~45kwh LiFe4Po Battery storage. The PV Inverter is an Fronius Symo 10.0-3-M.
This setup has been running totally fine for the last ~2 years.

Now... it's happening EVERY morning, that the solar inverter is no longer present on the main tab, but it still is in the menu. CCGX and Fronius are hard-wired, network settings haven't been touched - but of course, both are in the same network, (192.168.0.xxx / 255.255.255.0).

The CCGX does indeed 'see' the fronius, the IP address is detected and fine, but in the device list the fronius appears as "not connected", and if I enter its device parameters, it appears as "connected unknown".

As soon as I restart the CCGX (every morning) all is fine and the whole setup is running like a charm until the Fronius looses DC power (sunset). The next morning the above mentioned is happening again.... groundhog day^^.

Any clues?!


Grtz,

Fred

Happening again this morning - looks like this in the device list:

the device itself:unknown.png

I could remove it... but why is it disconnected? what causes this (nearly every morning)?remove-disconnected.png

network settings are ok, nothing to tweak here:

also, it says that ethernet is connected - and this RJ port is hardwired to the Fronius.
so why does the Fronius not display?!
