Thanks.
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:

If anyone is still using their battery setups, please continue to share how the experience is after some time has passed. Any hiccups or issues to note, or are things solid? I recently purchased a Goal Zero 1500 and was impressed with what it did to my front end. I was so impressed that I read a lot and decided to take the plunge with the Giandel 5000W Inverter and a single 5120Wh battery, this way I can plug my power amp in as well, something I can’t do with the Goal Zero as the fans kick in after only a few minutes. There’s some nice prices right now and the battery even allowed for a military discount (8%) on top of the sale, very cool! Once I get the new setup in place, I’ll return the Goal Zero. It’s pretty wild that for not much more money than the Goal Zero 1500, someone can get a 5000Wh setup by piecing together an inverter/battery/battery charger on their own. Very excited to see how this new setup turns out! |
@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 . thabk’s

There is always risk with anything electrical. Even when everything is plugged into the wall there are power surges and lightning strikes that can overwhelm any audio system. One reason I use a Shunyata power conditioner is because it has an electrical breaker built in to mitigate surges. Regarding the inverter, in my almost two years of going off grid, none of my audio equipment was ever damaged. I did however manage to damage the inverter and the battery charger. For the Giandel inverter, one should never plug and unplug equipment with the inverter on. I think I damaged it by doing this in a moment of haste. I was able to get a new 5000W inverter under warranty. I now always power all components off, then the conditioner, then the inverter, when I need to reconfigure the AC setup. Giandel they actually say to remove the positive cable from the battery. After making the change, I would power on the inverter first and then verify the AC voltage is back to 120V (US) before I power on the conditioner or any component. Regarding the Progressive Dynamic battery charger, I must’ve crossed the polarities at some point because the reverse polarity fuses blew. Fortunately, the fix was simply replacing the fuses which is not costly. The Ampertime battery has been very solid this whole time. It always runs cool. For what it's worth, here is a listing of features under "Safety and Stability" from the Giandel website:

I used the Venom V16 for source and Denali V2 for amp because the the Denali V2 has the QR/BB technology that helps with amps. With that said, for cost reasons and simplification I’ve sold both conditioners and now I’m using a single Shunyata Typhon T2 for DAC, preamp, and amp. I also have a pair of DC power supplies connected directly to the inverter and they power the Lumin streamer and other auxiliary devices such as network devices.
