But batteries are much simpler!I would think those things make more than some noise so a remote location would be required which would make long AC lines a necessity.I can see large installation making good use of this but not for most audio systems,...

|
Unless they are quite unusual I doubt your amplifier's output stage uses regulated supplies.My point was that PUREPOWER/Inverters, etc. deliver a far more constant AC voltage than the line and that this could be a reason people find them to be usefu...

I know the proprietor despises cheap DIY and I do, too. DIY should be a response to not being satisfied with what the market offers - not a cheap way to have something to listen to.All the while his system stands as a pinnacle of what one man can do...

One interesting thing about the inverter/battery is the constant AC voltage.My voltage is 122 volts 99% of the time with only a toggle up on the odd occasion and a toggle down on an even odder occasion.Since very few of us have power amplifiers with ...

I will be able to relax not worrying about the state of the batteries.The charger I use has three modes for charging that ends with a 13.5 volts float. It was made for LiFePo batteries but would work with AGM.I topped off the AGMs and my sister is g...

Got the "proper" batteries installed.Left them on the charger about an hour - voltage read 13.3 out of the box and never changed with an hour of charging.This morning after an evening of charging they read 13.4. The AGM wouild read 13.5 fully charge...

And one I do not enjoy at all! Rye whiskey is the only proper drink for a citizen of the US!I continue to wonder if the fact that my amplifiers are class a with constant load instead of one that varies has something to do with it. I wonder if a cla...
|
|
But i hate the thought of six hundred pounds in such a concentrated spot on a suspended floor.I have this thought: what if the AGMs had a more mellifluous sound than the LiFePo? And then I figure I need to fix another cocktail.Based upon the reports...
|
|
The irony is a battery cannot STAY at any voltage for long and as the voltage lowers the current requirement becomes harder to fulfill. The LiFePo will stay above 12 volts for far longer than the AGM if the graphs are to be believed. One m...

Which is what i thought I had posted a few times before.I assume 14 watts of that is the inverter.Before I disconnected the computer and USB box it was 640 watts.I hope I am not completely misunderstanding what you are asking for but it is entirely p...

|
The inverter has a meter that says 0 watts when nothing is connected to it - other than the batteries.As soon as something is "plugged in" it says 40 watts.GIADEL says the unit uses 1.2 amps/14 watts at idle. I guess it does not really turn on until...
|
|
And I wish I had looked more carefully before taking the cheap way out - which turns out to have become the more expensive way since I have no idea if anyone will buy a month old used battery.From the graphs the traditional lead acid batteries all pe...
|
|
You had mentioned the dry cells before but I was unaware of them.I went with the LiFePo the fellow recommended. I had ordered it before you posted this.The key is depth of discharge and I am not sure if they are specifying this. All of their specif...
|
|
Is how long it will maintain voltage and I was a FOOL to think I was saving money by using AGM.The fellow who gave me the idea used LiFePo but did not make it clear to this dunderhead that using the cheaper AGM would give one vastly reduced playing t...
|
|
I was using a DeWalt charger that would take the batteries to 14.something which of course fell quickly when the amps were turned on. That one was a 30 amps charger the one I am using now is rated at 55 amps and goes through three modes of charging ...
|
|
That spike went away.Did not seem to have anything to do with lighting. Completely mysterious - it just went away and has not returned.I have not done anything with the ground rod idea.I did listen with the ground wire unplugged - a plug with just a...
|
|
So after a month I continue to enjoy what the inverter does.I have found that the time one gets from 400 Ahs with the inverter's meter showing 640 watts usage is about 1.5 hours - you could get two if you let the batteries run down further but I figu...

If only we all could succumb to the realities of compromise earlier in life instead of thinking there is actually a Holy Grail Perfect Solution to any problem. Audiokooks would be much happier if we would.Kind of like polarity - no one really knows ...

I am using the Celestion Axi-periodic compression driver in the KLIPSCH K402 horn which I have boosted considerably when I noticed that the top one and one-half octaves were barely working when playing music so I figured WHY NOT? and it works just f...
|
|
Seems to me if one goes to the trouble of having a single ground point in the ground and there is but one ground point on the inverter and all is plugged into the inverter who needs an interloper? Schultz is reporting about the system of a friend who...
|
|
No question there is noise bleeding in from the rest of house - I just don't know it yet. When something is taken away I can miss it but am not the most perceptive before being made aware of what to listen for.John Broskie talks about us being broke...
|
|
Thanks for the spacing tip. At this point the only part of the inverter attached to the house is through the ground - and that is using a plug for just the ground lead into a close-by receptacle.My main amplifiers (tri-amplified system) are utilizing...
|
|
Isn't everything these days?I do not hear any extraneous noises coming from the box or through the speakers.Here is a link to the device I bought: https://www.amazon.com/dp/B08XXBVW35/ref=twister_B09H263X7F?_encoding=UTF8&th=1It says nothing abou...
|

That's much more than I am able to spend!All of the stuff came in yesterday so I spent an arduous day having to rewire my system.I had been using a 2000VA isolation transformer for each channel. All that was connected to the two transformers are now...
|
|
I was not aware that there were dry cell batteries in the size needed to do this.Looked around for some information on the TESLA POWERWALL and it seems to be another mystery - just like the man himself. (not a fan)I took the plunge and ordered two o...
|
|
Thanks for your thoughts.What is the TESLA battery? You mean the monster thing they use in the cars? Now that would be one hell of a battery!If I do it i will get SLA SGMs - gigantic LiFePo makes me nervous - I try to stay as far away as I can from...

I know Romy is skeptical of DIYers who want to do everything as cheaply as they can but there are others who do things themselves since they are not satisfied with what the market provides.
I can think of one loudspeaker system, in...

I am sorry it sounded like they bother me - far from it. I am glad to hear the sound of an active forum.I was hoping the smile could be seen when reading my note.It is just that with so many tales of woe from so few people one has to think that thes...

As one who loves this site for its vast information and the informed opinions of the proprietor I am fascinated by this thing which could be among the generator of the most number of responses here.I open my email and there are a whole bunch of posts...
