What happened?

The system does not register correctly what energy has been moved to the battery. It registers everything as "Consumption" See the picture for the 12-13h period: Only Consumption is visible (blue line), while the majority of that consumption actually went to the battery. This is not visible. I assume by not recording the consumption correctly, future predictions based on history will also be wrong.

Turning off "Has a DC system" on the GX device solved the issue. Although I technically have a small DC system (Power for the GX device itself), it was not measured with a separate shunt. Apparently the system did not do the calculations right.
