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?

Here is a link to a review:

rbertalotto - Vinnie Rossi produced a whole series of audio products that ran off batteries (DC power). I owned one of his Red Wine Audio amps for a while. The LIO integrated was probably his most famous. Here is a video on it.

Sbayne,, it was not my intention to upset you. Also, I am not arguing. I am electronics technician and know how to build an inverter so I know the theory. I am trying to understand an advantage of DC, to inverter over filtered AC power advantage.  I personally cannot afford the thousands of dollars for extravagant DC to AC inverters. My solution which is totally silent as far the human ear can tell (all that matters in music) is a cheapo furman filter strip for RFI, with 145v limiting shut off, then that power running to a Chepo Tripplight 1800w power regulator 85v to 145v regulation to 115v. Has more RFI filtering. My setup might or might not be the best for all equipment or situations. It works great with my Primaluna integrated , streaming, innuos setup. If you love the inverter solution, then Cheers!

Update on using my Bluetti AC200MAX as my power source. I finally got the fan to kick-on! I was listening to hard rock and electronic bass heavy music at fairly loud volumes. I was about 50 minutes into the listening session and didn't hear the fan  until between cuts. I repeated the last track and watched the power meter on the Bluetti. The surprising part was it never exceeded 450 watts which is basically what my system draws at idle. I'm guessing the extra quick power demands is what caused the fan to kick-on but those demands don't show on the power meter.  I'm going to keep messing with it by first, trying to repeat what occurred and second, plugging the amp into the wall and everything else into the Bluetti then playing the same songs as before - to see if the fan kicks-on again or if it was just a one-off occurrence.
