Using battery power to go off the City's power grid

I'm using a Bluetti AC200MAX 2,200 watt expandable power station to take my system off the city's power grid.  It runs off a lithium ion phosphate battery with a 4,800 watt pure sine wave inverter. My total system only takes about 450 watts so I have never heard the fan kick on - it is totally silent. The music comes from a completely black background, with a huge soundstage that sounds very natural. I know that Ric Schultz has talked about these types of setups and there is a very expensive Stromtank battery system that is marketed to audiophiles. Anyone else tried this type of setup in their audio system?

I love this topic...But to me, it makes no sense to convert DC to AC in an inverter, to power a piece of HiFi thsat then takes AC and converts back to DC to run the darn thing.

If we simply run the component on pure, clean DC and simply do away with the AC to DC power supply, we would get reduced costs, smaller unit, less heat and much more efficient topology. With the increased performance and sound quality of more efficient  Class D amplification this is very doable. Who will be the first company to embrace this idea?
