I have a system set up that when the conditions on the board are met, the relay for generator start is switched on (little sun). This switches the MultiplusII to passthru mode (the charger is off). The system works well. I have the ET340 set as a grid meter. All the load is only on OUT1 multiplus. (3x 5000/48v 3f config). In the past, a “generator” was set instead of the grid. I recently changed it and noticed that the VRM stops showing DC consumption (separate smart shunt set as DC system/DC energy meter. But only when I am connected to the grid. That is, the multiplus is in pass thru mode. If it is inverting, the DC consumption is displayed. Look at the pictures. Any ideas?
