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?

@sirnui  , thank’s for all the good feedback about using battery power .

I have one concern about using these giandell inverter .

Is there any risk for the equipment plugged into these inverters ? I have expensive audio equipment and I will hate to have them damaged by the inverter which cost a fraction of these equipment .

Also I see that you are using shunyata filtering after the inverter . Why a venom 16 on source component and not a Denali .

Thank’s 

I intend to buy a giandell 2000 w to power only my front end .

Does the improvement brought by the Shunyata in sound quality is really significant since going off grid is already a big plus .

Have you tried cheaper power conditioner such as puritan ? 

@sirnui    , thank you again for all the detailed information you are writing

I have tried Shunyata’s top of the line conditioners (Everest on down) on a battery/inverter and it makes a big difference. I have also tried Puritan conditioners and they make a noticeable difference as well. Value wise, the Puritan conditioners are hard to beat but I’ve found Shunyata TOTL to be better than Puritan TOTL. I can recommend both.

Yes , the Everest and Denali have very good reputation as line conditioners  , and they are very effective at avoiding pollution between components of the audio system which is by the way some time a stronger pollution than from the AC line .

Cost wise the puritan is 1/3 of the Denali and 1/5 of the Everest therefore hard to beat .

In fact you have now If I understand well two separated battery inverter system 

- One for DAC ,preamp ,Amp  with Shunyata Typhon 

- The second one for  Lumin streamer , switch etc...

Since I have a friend with a Denali  , I will do the test  with this conditionner .
