Solar Cell electricity effect on Audio???

[Alrainbow]

Here is what we should be understanding
All power we use has noise and many types
Even if very pure like a ps audio regen is the power gets polluted By the devices we use in various types of noise back into the power source.
the devices make other kinds of noise too
EMI , Rfi common mode noise and even dc offset.
Now having said this power supply in our expensive audio devices should And mostly does filter these various noises.
even some well made ones use a balanced power supply method. This eliminates most all types even the ones made by our Devices in there own power supplies
One big advantage of Solar is no dc offset
this is not important to small transformers if the windings are small enough in AWG but very important on lager transformers

Its funny how Soundman says inverters are noisy so filtration is a must. There are people out there now using and inverter and battery as a filter from the noise on mains. Ones man's filter is another man's poison.

such as?

You can start with an isolation transformer and a filtered power strip for good measure.

Thanks. Years ago, I found that an isolation transformer (large Bryston) did not yield the best sound from my amps. The Shunyata is much better in that respect. Just going by what I hear...

Here is a link to a study of THD using Ting monitors. Does anyone else have one of these in their home? I'm hoping to determine if I can use my Ting monitor to assess power quality in my home.
They also have a web page to check power quality from different providers.

The shunyata dinali works great it’s passive it removes noise but does not effect the flow
battery power supplies are good under certain circumstances
batteries are noisey and then you need regulators more noise
if you look at amps very few have regulation
And the ones that do it’s Input to driver stages Not output devices
my ML no 33 does regen inside this is I think a better way
there is nothing wrong inherently in solar
And I think we should Listen more and understand better.

That is why Torus is the only product I sell outside of the all copper panels I set up for people. I have had very universal success with with Torus. Some people still prefer a Everest on the front end. With my customers, non have said they hear a negative with the Torus. I could also say, on the front end, I have not heard of anyone sensing a negative with the Everest. Its just a flavor perception.

I have heard more people prefering a filter after a Goal Zero or Bluetti batter power supply than not. But not enough people have weighed in using a Sungoald or Victron to know the results.

I don't know you can effectively isolate a micro inverter array to be just Solar powered. There is always a sharing of the mains. Even if Steve says he is selling power back, there is a connection of the main power to the grid power to the solar power and the load in his house. I am pretty sure you need a solar system with a battery to truly "Island" onto the inverter and disconnect from the grid. But over the years I have never heard someone say they have issues with solar input. That is very good news.

Inverters are noisy devices so filtration is a must.

Do you have experience with this? An inverter installation that has been measured?

The noise is audible.

all inverters? Or inverters with THD > x? I'm genuinely curious because when our solar was repaired and therefore not operating, I heard no difference. Then, when they are operational again, there was no difference. My expectation bias was that there would be a difference, even if that might be small. I was surprised and also relieved.

@Rumpole provided a link that lists many power companies and the THD of the power provided. Given what I saw on the website and that high levels of THD are common, solar power with a good inverter would be an improvement in THD vs. the power company.

That said, different people have different sounds that they are sensitive to and that are intrusive. My theory is that this is the reason we choose certain kinds of amps with their particular noise profiles.

There may be inverters with some type of noise cancellation, but I have never owned or seen one under $1K.

Just as most people don't appear to be sensitive to the distortions and non-linearities of digital audio. I can't stand it.

Interesting. I built a DC blocker myself. Basically a set of caps on a diode. It was stunning how quiet my system became. TV was unreal good. But it also deadened my system so I got rid of it. I think the Isotek Syncro is similar.

I had a few diy DC blockers and then the Isotek Evo3 Syncro, and they all did this. Made things quiet, improved tv picture quality, but deadened the system. They give and take away.

Its been a few years since you posted, your friends design got around this? Is the pic from 2020 the last version or have you updated it since then?
