EG4 18k 130W usage with no loads

[inowhavesolar]

I'm using my EG4 18k with a critical loads subpanel. This morning, I turned off the panel's 100A breaker, cutting power to all circuits. Yet, the status of the EG4 LCD screen still showed 130W of usage to the home. What gives?

Would you be able to post a picture showing this? It seems like the idle consumption in normal mode, however, 130w is slightly higher than the rated 70w.
