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?

What battery system did you use? Perhaps not as good as what  @sbayne is showing here? 
 

This is most interesting to me.  I am building a new home and think something like this would be better than time and money spent on direct AC lines and power conditioners. 

Will do Scott. My Circle Labs A200 pulls 75 watts at idle and 400 watts peak! My total system draw is around 500w peak/max. I will need something powerful enough to run my system 10 hours continuos. I need the BLUETTI AC300 Inverter Module Generator | 3,000 and perhaps two B300 batteries. Perhaps one battery will do as my system is not running at peak. May do it!

Much less expensive than Stromtank!

Great post Scott! 

Agreed.  He is now on many threads and derailing each one of them. This thread has gone off the tracks and that is too bad really.

Thank you for that most interesting video.  Crazy hearing your local radio station so clearly on your AC line!
