Fronius error state 105 ac-coupled system with victron

Good day


I have recently installed a Fronius primo-6 together with a quattro 48/10 000 in an ac-coupled installation

the system works perfectly when the main switch on the DB board is off (thus making the system completely off grid) but when the Main switch is switched on the fronius gives me an error state 105 when reading up about this it means the ac grid frequency is to high... i tested the frequency from the grid and it jumps around 51Hz to 52Hz which should be will within the fronius parameters so my question is has anyone experienced something similar are there settings that are not correct on the fronius any help would be appreciated


thanks

Hello! Do you allow fronius to feed in the grid? Have you changed the settings on the fronius country setup to be Microgrid50?

I have exactly the same issue. I have checked all settings in both, the multiplus and the Fronius Primo and I do not figure out the reason why this happens. Any help would be welecomed.
