    incoming voltage

    This link was in the PS Audio June newsletter. Interesting reading even though some of it is beyond me. Makes me wonder even more about the validity in the context of the comments that I read from time to time that there are no quality issues with our power. Also even if there are issues, the power control in the amp etc will fix any small evils in the power out of the wall. My experience tells me other otherwise. The more you mitigate and improve the power you use the better the system sounds. https://www.vox.com/energy-and-environment/2018/6/5/17373314/electricity-technology-efficiency-software-waste-3dfs John

    incoming voltage

    @Addicted to music You and I definitely agree on the matter of too low or too high voltage. I assume that my high day time voltage is because of the amount of solar where I live. The grid is pushing harder (higher voltage) to try to resist the solar voltage coming into the grid. My understanding is that the transformer on the pole is receiving 3 phase which is then split by the taps into single phase for the various houses. If this is not balanced there can be issues. I became interested in the SolarIQ because of the high day time power voltage and the electrician suggested this solution. My solar is an Enphase system including the inverters. They are underneath the panels so that part of the roof does not get heated as much as elsewhere. They have worked fine for the past two summers. I am assured by the supplier that temperature is not a problem at all. John

    @LogicprObe @david j I did do a post about the Solar IQ in the power cable topic a little while ago but whilst the post was read by a number of people there was not a lot interest in the topic at the time. I was waiting to see whether there were savings in my power bill before I said any more. I won't know until late next month. The device is designed by a company in Melbourne and it seems to be manufactured in the Philippines. The company is called Edge Electrons. There is a link to the company website in the post in the topic I started. Below is a screen shot of what is happening at the moment with my power as per the Solar IQ. 1.38kW is going out into the grid and I am using the balance of what is being produced John

    incoming voltage

    @david j Some of what I say below is contradictory to some posts above. So be it. It is my experience which some may find useful I am surprised that with 212 or 208 volts that some things even work or at best will struggle to work. As has been said above you can have the grid supply checked. When I complained about my day time 258/259 supply volts the technicians turned up promptly in the rain at night to do the check. My understanding is that with the proliferation of solar the supply voltage increases to overcome the solar coming out from the residence. It is a fight of pressures. It is also my understanding that high supply voltages will mean that appliances will "wear out" more quickly. As well solar can and will stop working when the supply voltage goes into the mid 250s and above. Also with high supply voltages you are using and paying for power that you do not need to use. Another thing is the variation of the THD of the supply power. I am told that this is higher than some us may realise and can impact on the quality of my system. Others may disagree with this observation. I have had installed in my house a Solar IQ connected to the switch board. It controls the voltage in the house. When it was installed the default setting was 220 volts. There is an approximate 4 volt drop in the house so appliances etc were getting 216 volts. The overhead fan for example would not start or ran abysmally slow on the lowest setting. Hence my doubt about 212 volts above. With the 216 volts my audio system SQ was fantastic, incredible amazing etc. No imagination. Wonderful!!!! For other reasons the default on the Solar IQ was increased to 230 volts so the system now gets 226/227 volts. Still good but not what it was like with 220. With the Solar IQ the THD is zero and may explain why for me there was a perceptible reduction in system noise floor. Very occasionally the Solar IQ has a brief rest and the house voltage is as per the supply side. There have been a few times when I have been listening and was not aware of the rest period and I think the system is not good tonight. I check the voltage and the system is getting 250+ something and then the default setting kicks in and everything is good again. It is quasi blind test when you do not know it is happening. As well with the 250+ the fans are faster and the lights brighter. I am waiting for my utility first bill to see if there are the predicted savings in my power costs. Fingers crossed. John

    I am told that the problem is prevalent everywhere and not just WA. My supply voltage in Victoria goes from mid 240 volts out to 259 volts. Right now the supply is 257 volts I will get more information hopefully next week regarding this matter. Also power is not just about voltage. I think that is important to realise that some times it is not as "clean" as we may like it to be. John

    @PKay I am curious to know what you mean by stable power supply? John
  7. It is all about relative affordability. My audio journey has only been for the past 8 years. In that time I have learnt several things. On thing is that as in most things in life there is a relationship between cost and performance. There are many examples of well chosen bargain lower priced audio equipment that have relatively serious performance outcomes. However higher quality more expensive well designed equipment will outperform the lower priced equipment. John
  8. @LogicprObe I hope that is doesn't. There are some underlying matters that influenced my fanciful question It seems to me that many people want to be off the grid. The reasons are varied and range from costs through to life style. My question was taking the whole matter of off the grid to an absurd conclusion. Will there come a time when there is no grid? I actually cannot envisage that situation and as you indicate what happens with even just high-rise buildings. There will be people even in single dwellings that will not be able to utilise solar effectively. This will include potential solar users who want to have solar and be on grid but are prevented from connecting to the grid because the grid cannot cope with the additional feed in. A problem is as more consumers go off grid the costs of the grid infrastructure will need to be amortised over fewer customers and the unit cost will consequently rise. Is that tenable? Maybe there needs to be a way to encourage grid connectivity for the benefit of all. Supposedly at the moment the supply utilities are being investigated for loading up the connectivity charge above the real cost. Surely the the supposed scrupulous companies cannot be exploiting the consumer? My understanding is that if you own a piece of land and water and sewerage is available and even if you are not connected you are liable for some utility rate charges. As well, if you want to have a telephone land line you ultimately must be connected to the NBN if and when it is available where you live. Being on the grid gives flexibility. To encourage on-going participation with the grid, reduced connectivity charges may be necessary plus higher feed in tariffs. Just the thoughts of an idle mind John
  9. @Addicted to music Your post to me opens up a multitude of questions including the following. How do you quantify cheap? What is environmental in the context of solar and other renewables? If renewables develop as you would seem to advocate and as do I, do you expect that the grid will disappear in the foreseeable future for everybody? What will replace the grid? Will there be a need micro-grids to develop as I would suggest they should and who pays for the infrastructure and the ongoing support? To me the grid has to continue yet as the number of off grid users increases the grid costs will be amortised over less users. Is that equitable on a societal basis? It is the same with electric vehicle users who do not contribute to the cost of the roads that they drive on at the moment. Obviously there will have to be significant change in the future on several fronts. The interesting question is what government will have the courage make the changes, what will they be and when will the changes be implemented. Meanwhile Rome burns. To me a major problem at the moment is an effective plan for the integration of the impact of home solar feed in into the existing grid. In some streets now people cannot have solar and yet still connect to the grid. The grid system is not able to cope with in-balance of the feed in. John
  10. @nil Unfortunately some of the posters are to me not overly helpful in the grand scheme of things. You need to try things and make up your own mind and take on board what suits you and naturally that includes what I say. I am like you. My knowledge about the technical intricacies of power are beyond me and it is bit too late for me to learn. The one thing that I do know is that the treatment of power is critical to a quality audio result. It is an absolute to me. If you begin with low quality you will end up with the same at the final end in what you hear. My post is not about solar or batteries per se. For me it is about the control of the voltage of the power regardless of the source. In the short time that I have had the SolarIQ installed I have had virtual cloud cover the whole time so the solar power has been negligible. At night there is no solar and I do not have batteries yet. So, my system is running mostly from the grid. Incidentally my system is always better after 9.30pm with no solar. I do not know why the SolarIQ has the name that it has. I guess it is about the fact that the house solar only sees a desirable operational voltage that delivers cost benefits. My post is about in my case the wonderful beneficial outcomes of the control of the house voltage that the SolarIQ achieves. Besides voltage control it may do some filtering. Whatever it does, the outcome is truly fantastic. A number of posters on Stereonet have claimed two things often repeatedly. · The quality of the power in Australia is "good" and does not need treatment especially on the east coast which includes Victoria where I live. · Secondly the power treatment in the equipment will mitigate any power quality problems especially in good to high quality equipment which I have. So, life in the context of the supply power quality and the equipment treatment thereof everything should be should be fine. That is not the reality. Based upon my short term experience with the SolarIQ and other power treatments that I have, my position in respect that power quality is not an issue is a total nonsense. If you want a quality output you must start with a quality input. To me it is unfortunate that the deniers possibly influence others not to try. As I have said I am a believer and big time. Power treatment such as conditioning is not a dinosaur. Rather it is a new adventure. I say go for it. Ignore the deniers. They are missing out. John
  11. @nil The treatment of power for our systems has interested me for some time. I do consider that the relative quality of the power supply varies and the variation can impact upon the outcome of what we hear. I also consider that the variation in quality is more significant in even the eastern states of Australia than some people are willing to acknowledge. Just look at the significant variation in the supply voltage that people experience plus the fluctuations. My supply power can go from the low 240s to the high 250s volts in minutes I also acknowledge that I understand an absolute minimal amount about the science of power. My experience with the treatment of power shows to me that for my situation there can be important beneficial outcomes in the performance of my system. It would expect that others could achieve benefits also. I have read probably every post about in every thread on Stereonet over the past few years. In some instances, I responded outlining my experience. When there has been treatment of the power that I use I have in some instances perceived a benefit. An interesting one that was done by the power company and not me, was a bigger newer supply transformer on the pole near. A definite improvement. I started a thread about the SolarIQ that I have just had installed. My post explains why I did it etc. I started with the SolarIQ on the basis of voltage control. I have listened to my system over the past few days even early the morning. I can't stop listening. I am not getting anything else done. Whatever the treatment that the SolarIQ performs, the result in terms of a benefit in the SQ is amazing. I am a definte believer in the treatment of power. John
  12. I think that I need to explain why I started this thread. When I decided to start the thread about the SolarIQ I found that there was already post elsewhere on Stereonet about this device from a few weeks ago. There had been no responses to the question from the original post about the Solar IQ in the context of audio performance. I thought the thread was lost in the wrong place and now maybe the two threads can be combined. Maybe nobody had tried a SolarIQ After a period of consideration, I now have a SolarIQ and can comment on its performance. I live in a rural area. The voltage of the electricity supply to my house fluctuates between 240 volts and out to at least 258 volts and sometimes even slightly higher. It is mostly above 250 volts. As I write this post the supply voltage is 256 volts. I have always been intrigued as to whether this makes a difference to the SQ performance of my system. Is it better or worse as a consequence of what I consider is the reasonably high voltage? I have a micro inverter based solar system and I was aware that the relative performance of the micro inverters was influenced by the supply voltage. My understanding is that as the supply voltage increases the performance of the inverters decreases especially as the voltage goes above 250 volts. In fact, solar can shut down when the voltage hits the mid 250volts A while ago an electrician was rewiring my phone points prior to NBN connection. I asked him some questions about the high voltage and what could I do about it. The electrician suggested a SolarIQ which would reduce the voltage used in the house down to a steady lower voltage. With the SolarIQ the inverters only see the volts that it puts out. Some experts supposedly disagree with this phenomenon. The street supply and the solar is wired into the SolarIQ. It is then wired to the switch board so that what goes in to the switch board and therefore the house is the setting of the SolarIQ which is all the solar sees. With lower voltage there supposedly would be of benefit in the context of quantity of the improved solar performance, less power consumed in the house and the reduced wear and tear on appliances using the lower voltage. The electrician also said that there may be a benefit for the SQ for the audio system. All very interesting. To me it became a matter that if there was a benefit to the audio so be it but it was about the potential of the dollar savings. My focus shifted from the audio and shifted to the potential $$$ savings overtime. Any audio benefit became a maybe. I decided to proceed and ordered a SolarIQ. It was installed last Monday. Initially software wise it was not properly set up. It has been tweaked over the last few days. At the beginning it fluctuated between working as it should and not working. Today it has been fine. The expression was that it needed to “learn my situation”. Initially it changed randomly from the normal street supply to the controlled supply. It went from 250+ to the control default of 220volts. With the random changes I was subject to an enforced AB testing for the first couple of days. When the voltage went down to the 220 volts output there was a noticeable beneficial change. The noise floor was definitely reduced. The bass was more obvious. I felt that I needed to turn the volume up slightly. The most significant change was that the sound was far more lifelike and musical and there was enhanced three dimensionality. So, there was a pleasing audio benefit. It was decided that the 220 volt default setting was a bit low for me as there was voltage drop in the house by the time the power reached the system of between 4 to 5 volts. My solarIQ has now been set at a controlled 230 volts so the system gets 225 volts. My impression is that with this higher setting that the three dimensionality has been reduced slightly. The rest of the audio benefits are as is when the default output was 220 volts My audio system tends to high end so to be able to achieve a benefit of an increase in the musical realism with the SolarIQ is pleasing to me. In fact, the outcome has been surprising. I did not expect much from the audio outcomes. Now I do not overall care whether I get one cent of benefit in terms of the solar etc. I started from an audio objective and went to the dollars and now it is that both are achieved. I am intrigued as to what the SolarIQ has done in terms of the treatment of the power to have a noticeable beneficial impact on the audio outcome. The impact is definite. It took about 5 hours to install so it is not easily removed. I have no financial interest in the company that manufactures and sells the SolarIQ whatsoever. I am just pleased with my investment A link https://www.edgeelectrons.com/edgeiq John

    How to quote?

    @Snoopy8 How do I quote a post from one thread to another new thread that I want to start in another section of Stereonet? Thanks John

    @Frameperfect Being probably a bit pedantic, but to me in the context of a physical medium in one way the CD is similar to the LP. What is on the ordinary CD is not a digital file. It is my understanding that what is on a CD are pits and troughs that are "read" by the laser in the player. In turn what is read is converted into a digital file in the CD player that can then be played via the DAC in the player. When you rip CD the pits etc are still read and converted into a digital file. John
