Update
Another thread suggested that the Lost of Mains (LOM) could be causing the problem. The grid code password was obtained and LOM disabled over a weekend, this made no difference the system still did not go into inverter mode.
I conclude that there must be a problem with the CCGX. Two Multiplus-II has been on the system and the problem was seen on both leaving the CCGX as the most likely cause of the problem.
LOM has been re-enabled.
got same issue Ive moved the solar pv today as it wasnt charging so i terminated it into the consumer unit. this is now working, however got same issue as you it only inverts when main grid incoming switch is off. hopefully we can get it sorted.
Problem solved. Using Victron Configure go to tab "UK grid code setting" in there uncheck "Use Aux1 if (availabel ----". You will need the Grid Code Password which you can get from your system supplier.
I think you could just move whatever you have on Aux1 to Aux2 if it is not used. I have AC_sensor on Aux1 which I know can be on Aux2, have not tried this.
