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:

@sbayne Oh that should be fun! I think I'll do that! Thanks for the suggestion! Is there a limit to how many pictures can be posted?

@dpop - Great. I don't think there is a limit.

This is just one example of a Battery Room at a Data Center (ie, computer farm). These batteries are for mission critical UPS power.

So what about when the battery is charging, is there any noise?  I tried a couple of similar devices and both had clicks when the charger went on and off and the other also added a low hum.

what is different with this product?

Thanks.

@curiousjim You may not be speaking to me directly, but just out of curiosity, are you referring to mechanical clicks, or audio clicks?
