Multiplus not inverting when grid connected

Hi All,

My multiplus II 5000 is not inverting except when I cut the grid. Also when grid is connected it just charges the battery no matter what I do.
This may be related to a firmware update that I did yesterday. I have reinstalled the ESS assistant after the FW update and the MP is in the “on” state, i.e. Inverter and charger.
I believe the settings haven’t changed but I cannot see what is causing it.
Any ideas would be much appreciated.

Thanks in advance,
