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?

Not sure why you want to be off grid other than during a thunderstorm?

With proper voltage regulation and filtering grid power is fine. Inverters can be noisy too. Especially under quick peak loads.  Much power thermal losses with inverters too.

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!
