Hi Brainstrust,
I have a Fronius Symo AC Coupled to a Victron Multiplus II
DC PV ---- Fronius ---- AC Out 1 (Victron) --- AC In 1 (Victron) --- AC Load
I have followed the instructions to set the Fronius to MicroGrid 50 mode (https://www.victronenergy.com/live/ac_coupling:fronius)
The Fronius and Victron are on the same Layer 2 segment and have a Layer 3 IP.
The ESS Assistant has been loaded on to the Victron.
When the Fronius boots up, it seems to sync the AC frequency, then tries to take load and trips the Victron.
Running out of things to investigate.
