For all you people "Using battery power to go off the City's power grid', does your stereo sound as good in the daytime as night?
People often say their stereo sounds better at night. Is it dirty power from the grid or something else?
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?

This is just my educated opinion but I think there are a few key things that a powerful battery/inverter system offers over the average 15A wall outlet. It’s separated from what can be a noisy grid. It can offer more dynamic power (from a large bank of capacitors?) and it can offer higher maximum power (30 amps plus). Lastly, it can offer a better AC sinewave (better THD) to power supplies that were designed with perfect AC sinewaves in mind. I believe all of these points matter in a good sound system. Where the battery/inverter and 15A wall outlet may be at the same level is in the area of component to component noise. I’m talking about the noise from the streamer’s power supply travelling only a few feet across power cables to interact with the preamp’s power supply. This type of noise may be more problematic than anything on the grid. So this is where an excellent power conditioner comes into play. Some well designed power conditioners tackle this type of noise and they tend to offer outlet to outlet isolation at some level. 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. |
And replaces it with a potentially noisy inverter.
Greater than the dynamic power available from your local electric utility, which uses banks of capacitors at the substation? I don’t think so.
A good power supply doesn’t require "perfect AC sinewaves." |
