I have seen other posts with similar issues, but that doesn't answer my specific case.
Note: ALL load is on the AC1 of three multiplus II, 3 Phase config.
There is a victron 3-phase powermeter on the grid side.
The battery uses SimpBMS via CanBus.
Why is there a 30% discrepancy in battery discharge + Grid vs load?
Why do I have a value under "AC Loads" when the AC2 output of all 3 Multiplus is disconnected?
Why does total consumption show battery discharge + Grid?
Where do the 30% go?
