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:

mijostyn - "Doing a whole system based on a total of 4800 watts of Class A power is another story." What do you have that requires 4,800 watts of power? For instance, my 50 watt Class A amp draws 300 watts and the rest of my system including a tube preamp, DAC, streamer, reclocker and various accessories draws about 150 watts - so a total system draw of 450 watts. 4,800 watts seems WAY too high.

mijostyn - I just checked out your awesome system! Very nice. Your Parasound JC1 monoblocks draw about 250 watts each at idle and may draw up to 1,200 watts each at full power. So your amps, potentially, may draw 2,400 watts if completely maxed-out when used with your SoundLab speakers. There are definitely powerstations out there that can handle 2,000 - 3,000 watts off grid. The Bluetti EP500Pro, for instance, can handle that load and costs about $5,000. Not cheap but nothing as compared to the Stromtank offerings. As to getting "minimal benefit" for going off-grid for your whole system - all I can say is you need to hear it before passing judgment. The benefits are substantial. 

You stepped in it @mijostyn. Can I offer you a water hose to clean off. You are arguing religion not reality.

So you can spread whatever fantasies you want @sbayne? Na, I think I will stay around for a while. I could write 500 tweets and still not keep up with the nonsense so many peddle here.
