Losing storage

I just set up my brand new AC 300 with two B300 and one PV 350 panel. At 11 o’clock last night it was 98% but this morning at 9 AM it was down to 75%. It was not plugged into the grid and the only thing that hooked up to it is the PV 350 panel. I’m wondering what causes it to draw down?

If you do not have the unit turned off, it will consume power and more so if the AC output button is turned on.

Hi @LarryL

sadly, the AC300 have a really high selfconsumption. I do have the AC300 with two B300 myself and its really recommended to turn of the unit and the B300 when you not using them.
