Solar charged battery system providing electricity for audio system

We are putting in a solar/battery system for the house. As a plus, I'll be running a new sub-panel with 20 amp lines to the dedicated audio room.

As the electricity will be from a very large battery and not the grid, is there a need for a filtering or regeneration system? I ask now because that is the next 

in the list of things to do for the system...upgrade from the Chain Lightspeed that has been used for the last decade. 

 

Does anyone have experience with this?

 

I was wondering about solar power too. I guess the quality of the solar ac depends on the quality of the inverter that makes ac from the dc. Or are there already audio mains regenerators that have a dc input?

Whats an audio mains re generator?

Plenty of invertors out there to choose from, from companies that specialise in designing them.

 

 

 

I mean something like a ps audio, DirectStream Power Plant 12 but with a dc "battery" input. 

I have no idea how the sine wave looks or the noise on a normal inverter is.

I thought it might be time to pipe up and give some actual observations from someone who is using a relatively simple version of solar powered audio system.

I currently uses a GOAL ZERO YETI 1000 LITHIUM PORTABLE POWER STATION with 200w of solar panels for charging, 2 extra AGM 12v batteries for reserve capacity and a AC to DC charger if I need more current to recharge the batteries faster. The Yeti is a 1500w pure sine wave inverter. 
 

I run all my audio equipment and music PC off the grid, excluding my subwoofer amps. I have a separate ac circuit running 6gauge wire in galvanized pipe directly from the outside service entry to its own breaker panel and then to a 5Kv Topaz balanced transformer. Currently, I run just the subwoofer amps off that balanced power.

 

I want to qualify my observations by stating, I have never put an oscilloscope on these circuits to get the actual measured noise, so again these are my observations on my system and my electrical grid.(which for all I know could be way noisier than any of yours!)
 

It is literally no contest the pure sine wave inverter run off battery power only is dramatically better than my dedicated AC circuit in every measure of listening enjoyment. I would equate it from going from a  crappy smps to a high grade linear supply. Blacker background, more refined purer tone, much deeper bass with way more musical density. and much more information retrieval. The soundstage is much broader and way deeper, classical music is portrayed with a much more accurate sense of scale and with much better delineation between the musicians. There is no smearing of things as the music gets more complex.

FYI, I am not new to this audio game, having been in search of audio nirvana for over 35 years. So my system is pretty well sorted out and I have a lot of equipment on hand to make comparisons with, so whether I’m using my Phasure NOS1 with all the factory upgrades or my Chord M Scaler and Dave directly driving my 115db/w Orphean Horns, with highly resolving open baffle mid bass and subwoofers, The improvement my off the grid power power gave my system really stunned me, like “jaw hanging wide open, listen to your whole music library again!” stunning!

Very nice Todd that’s the kind of solar system I had in mind. Good to to hear from an actual user that it is so much better then a dedicated grid power with isolation transformer. I presume you also have dedicated earth rods?

 

And just because we stating our motor vehicles, this is mine: KTM 1290 super adventure s.

Hey Ricky,

 

Yeah the earthing rods with the special soil mix, the whole nine yards. I really should buy a decent scope just to get a visual of what’s really going on.

 

So about a week ago I heard this out of the ordinary sound coming down the street and could hear the turbo whine, it was the KTM, my neighbor just got one! It’s frigg’n wicked! You must have a blast!

 

Whoops slightly OT, some are a bit sensitive about that, but I think you have a KTM x-box in mind. On my two wheeled version it’s a blast too.

 

Anyway, is there any particular reason you choose the yeti, other then the pure sine wave? Why not more in home kind of system and a bank of deep cycle batteries. Sorry my enthusiasm is running wild.

 

darn it my food is burning

You will find that using an isolation transformer on the output of an inverter will greatly reduce common mode noise. 

Dont expect miracles from inverters as even the good ones don’t provide better than 2% THD. 

Earthing systems are critical and need to completely compliant with wiring rules where you live for safety as well as noise reduction.

 

But is the 2% THD better or worse  then what the mains does. Well it depends on the area of  cause.

Hey Jud, thank you for your insightful post. I am now running my low capacitance Topaz transformer after my sine wave inverter. There is definitely not some dramatic chance in the sound quality, but I’m sure it is not worse and probably would measure better.


I wanted to clarify that while I am listening to my off the grid system, it is running strictly on DC battery power with no solar or other charging devices connected.

 

And I did want to reiterate, that I have a extremely thoroughly implemented dedicated AC system coming directly from my homes outside service entry not from my existing inside main breaker panel. And truly there is no comparison, the DC derived sine wave inverted AC absolutely crushes that dedicated grid AC!

 

So the question is: could there be other reasons besides line ripple that contribute to that drastic improvement of the DC derived system?

 

Could it be that the ac near you is heavily polluted?

I had the same thought... could PS Audio produce audiophile inverters using just the inverter stage of their regenerator products. I don't know what DC voltages these home solar/battery systems use, and how it compares to the internal DC used in the Power Plants.

 

I have asked Paul, just for fun. I think it’s a good idea, “the green audiophile” benefiting the environment, SQ and maybe cheaper to build. We’ll see if I get an answer.

@thotdoc I thought this was a thread about Solar charged battery system providing electricity for audio system. 

It seem it’s gone OT to “the green American” thread. 😳

I like to listen to music in my "green" home. 😲

 

Absolutely nothing wrong with that. If I had enough money I would build my house off grid as much as possible too. Nice design, big audio room.
