I have a off grid home so it uses a bank of batteries which then go thru a whole house sized large inverter (Schneider). The inverter is where one can get noise and I have not tested mine. With that said there is virtually no noise in the system but I am also using differentially balanced gear. Super happy with the sound and whole house setup.
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?

Obviously using for a small house needs a larger unit. This is what I have or maybe 1 gen newer. 4.5k.

I agree with DC power coming from batteries and many devices running off DC there are energy and cost savings. However DC devices run at various voltages which would require specific transformers. Plus battery systems run at varying DC voltages. Many small off grid setups are 12V. Many home systems are 24 or 48V. So while it seems great in principle, pretty sure any implementation is tough and needs customization, hence 110AC. Our off grid setup is 48v and I run class D electronics. The system uses about 50w when running which is an integrated amp, streamer, and speakers with a sub. I turn the sub and integrated amp off at night which reduces the dummy load from about 30 watts to 5 which is just the streamer. |
