Hello
I'm setting up my Multiplus II, I like to disable the ground relay setting but the checkbox is not able to uncheck. My grind is a 3f grid without N, only L1,L2& L3. Belgium grid is selected.
firmware 2623496 is installed. The multiplus is not connected to the grid at the moment, only battery power, could that be the reason?
Is there a possibility to disable the ground relay?
Kind regards Tim
