Fronius gives error 105 after firmware update on Victron Quattro

Q&A and troubleshooting

I updated the firmware on the Quattro 5kVA and now the Fronius Primo 8.2kw gives an error 105.

I have an AC coupled system with an extra Victron 150/60 MPPT. I use MG50 on the Fronius and it worked for more than 3 years. If I shut down the AC supply to the Victron the fronius starts up and works fine. I see this issue came up with other users but I see no solutions being posted to the problem.

Any advise would be greatly appreciated,

Did you re program after the firmware update?

So the fronius works fine when the system is not grid connected and is not being frequency shifted too high (error 105).

Check if the fronius also needs and uodate then re check the controlling priorities in the dno settings.
