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:

I just showed up because of something I recently was read into. Which is very important to this discussion. "Or shall be shortly".

So if you are on the edge and about to make an investment in this type of gear?

 You "may" want to hold off for a few months...

Seriously!

And everyone here will know what I am talking about when it happens....

It is just that big.

Once "Released".

But I cannot say anything at this time.

Anyways, Have any of you noticed just how nifty

those new "Solid State" computer hard- drives are for PC's?

Simply '"amazing" aren't they?!

Yeah that "solid state" hard-drive tech will change everything!

sirnui,

Did you connect your Shunyata to the single 30A RV output of the Ecoflow, and then your components to the multiple outlets of the Shunyata? As I understand it, this is the analogous sequence used by ricevs’ friend Oeno, with the Giandel supplying the pure AC to the Puritan filter, and the components being driven by the Puritan filter. The Giandel is like the Ecoflow, and the Puritan is like the Shunyata.

Thanks for your report. I look forward to your Amperetime=>Giandel=>Shunyata experience. I like my Shunyata Denali 6000 alone, which extends HF in particular, but also tightens the lower freq.

The analogy is correct and your statement regarding all the connections are also correct.  Power conditioners like the Shunyata and the Puritan can and in my experience do benefit from an inverter/battery that sits upstream.  It could be because of the cleaner AC or electrical isolation but I'm not 100% sure.  So that's why I demo and listen.  I don't like to just wonder if something is good or not. Part of the fun for me in this hobby is to try and experience various audio gears. It's all about the experience for me.  

The Amperetime battery and charger and the Giandel inverter arrived over the weekend.  Now I'm just waiting for the battery cables to arrive and then I can hook up everything and demo.  The AC adapter I made previously for the 30A RV connection has been modified and will now connect to the AC terminal block of the Giandel. Like oeno, I don't simply connect the Shunyata/Puritan to the 15A or 20A outlet.  We utilize the 30A+ outlets. 

One correction I want to make. I no longer have the Shunyata Everest/Omega XC combo. I now have the Puritan PSM1512 conditioner with Ultimate power cable.

My near term goal is to get back to the performance level when I had the Ecoflow and Shunyata combo. I'm not there yet with the Bluetti and Puritan combo but I'm hoping the Giandel and Puritan combo can get me there or even top it. 

Terrific!  I had thought the Giandel just has standard 15A outlets.  I doubt that a 30A outlet would be better for sound quality, although it will enable higher power demands.  Adapters can degrade the sound, so plugging the Puritan with the Ultimate power cable directly into the 15A outlet of the Giandel should be the purest way.  I would be incorrect if the Ultimate cable already has a 30A male connector.

My Shunyata 6000 is plugged into the 15A wall outlet, will much more clarity and HF extension than no Shunyata.  I am not interested in high power.  Most of my music only requires low power, with occasional peaks.  Clarity and resolution are appreciated mainly at low power.  That's why high quality class AB amps offer  class A operation at low power, and then AB when high power is required.  The ear is most discriminating at low power.

In any case, you can try the 15A and the 30A outlets on the Giandel, and see if there is a difference.

When I play music with my active speakers, the total power draw for the system is about 220W.  And when I listen to the headphone system, the power draw is even lower. So 5000W from the Giandel is overkill from a pure power perspective but I think audio quality comes from the parts and wires that can support that 5000W power draw.  For example, on the Ecoflow, I studied the parts and wires for the 30A outlet vs the 20A outlets and they are different.  This difference should cause a differece in sound. Being the tweaker that I am, of course I will test this theory on the Giandel :) My experience with Shunyata gear over the years tells me that wire gauge and quality matter and the quality of the parts and connections matter.

I agree, the AC adapter I plan to use with Giandel will have a negative effect but I have a hunch this will be overcome with the "higher quality" connection on the Giandel.  We will see.
