Weird desk fan has more power with grid pulling in power 6000XP

I just got my 6000XP hooked up last weekend, it was just running on battery while I'm sitting at my desk, but the batteries were getting low 30%, so I decided to kick on the grid charge and the fan was noticably pushing more air when the grid started charging, like louder and everything. Has anyone noticed that?

Your grid might be a bit higher voltage, like 124 grid vs 115 inverter or something.

I had that but I found a setting in my inverter to dial it up to 121.
