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:

It would be interested having one of those to compare with my PS Audio PP.

Other than being truly  "off the grid" supplying the AC for the system, same principle. 

Looks like a less costly one too.

I see you have a pair of "that brand" speakers. The threads are entertaining.

Right. Same concept as the PS Audio PP since it generates a 120v/60HZ pure sine wave from its inverter - except mine is coming off a battery.

I have a off grid home so it uses a bank of batteries which then go thru a whole house sized large inverter (Schneider). The inverter is where one can get noise and I have not tested mine. With that said there is virtually no noise in the system but I am also using differentially balanced gear. Super happy with the sound and whole house setup.
