So i have a three phase system using three Victron Inverters, 5 MPPT's and 32 panels.
I am generating rather a significant amount of power and especially as it is nice and sunny.

For the first year, on sunny days like these, i was only using about 15-20% grid power. During the day, i was not drawing from the grid at all, and even when the battery kicks in, only battery till it reached SOC.
Had the inverters updated to the latest firmware, and now, even when generating more than enough, i am drawing almost the same from the grid.
I am guessing it must be something in the ESS settings.
Any idea what?
