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:

OK, used the Bluetti on the amp (that draws 35 watts at idle).........the bass was a little better than the Goal Zero but the imaging was not nearly as real.....you can see the space of the recording venue and each instrument is in its own space more with the Goal Zero......The Goal Zero sounds a little soft......the Bluetti sounds more like the zippy wall sound. When listening with the Goal Zero you want to turn it up 2 db and then it is goosebump heaven. time The Bluetti is sitting on the floor and the Goal Zero up on some wood blocks. The Goal Zero also has a PPT AC thangy plugged into its spare AC outlet. Really the test is mostly meaningless. By having the amp plugged into the Goal Zero you are getting more noise interaction from the amp to the other components.....so, I should have a second Goal Zero just for the amp to be fair....and also a PPT thang plugged into the Bluetti and also have it off the floor.....everything makes a difference.....But, I will say I did not want to go back to the Bluetti after hearing the Goal Zero again......If this baby denuded Goal Zero sounds this good what the heck does a 5000 watt Giandell sound like? I want to know.....Maybe I will start a go fund me page and you guys can buy me one.....he he.

The Bluetti I have here is the AC200P not the AC 300 which is an inverter with out battery......this one has the battery.

@ricevs - Too bad it was actually the Bluetti AC200P which uses their older inverter design that according to Hobotech is much noisier than their current MAX series of inverters. The control software is also different. Anyway, I've been looking at your webpage again (great info there) and will probably build a Giandel 5000 system.  

I have an Entech power line noise analyzer arriving on Monday. OCD Mikey used one in his videos regarding the Puritan conditioner and they are fairly cheap.

ricevs,

Too many variables between the compromised Bluetti AC200P and the Goal Zero Yeti 400 with its woodblocks and PPT.  I thought you were using the Yeti with your front end only, not with power amps.  The most meaningful A/B you can do is between your Yeti 400 and your friend's Amperetime/Giandel, both used only on his front end.  Your Yeti 400 can't handle the power amps, unfortunately.  But maybe you remember the Yeti 3000 which can handle the entire system, and how it compared to the A-time/Giandel in your friend's system.  How did the Yeti 3000 and A-time/Giandel compare for just the front end, and the whole system, for bass and the other sonic aspects?
