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
