Using battery power to go off the City's power grid

@ricevs Good that you can hear the failings of the interters you are testing.

About your comment on PS audio, I don't understand what you are saying or else you don't.  Inverting is changing DC to AC.  The PS audio rectifies the DC from teh wall and the converts it back to AC, the definition of an inverter.  

Are you trying to point out some other subtlty?  

But I say it is the quality of the inverter,  the quantity of amperage, and the low output impedance, that makes a quality power supply expensive.

Viber,

I have never heard a Giandel Inverter.....I KNOW nothing about how is sounds......but I trust my friend and know his system (which is incredible). Here is what I will tell you......the Giandel will give you everything you ever wanted and more........or it won’t. he he

The PS Audio uses a generated sine wave and a power amp to do inversion....very different from the "normal" inverters. I don’t know the technology.....but looking at the schematics it is very different from a "normal amplifier". Actually, it does not matter about terminology.....of what does what.....What matters is the sound. Even Jay on his forum likes his $27,000 Stromtank inverter better than the $10,000 PS Audio thang (whatever you want to call it).

The quality of the inverter is based on infinte things. When I was modding the Exeltech inverters back in the 90s.....I changed the output filter cap from a Panasonic cap to a Wonder cap and the sound was more pure.....a gazillion things make for sound differences. The inverters out there are not made by audiophiles who listen to every resistor, wire, inductor, cap, damping, etc. etc. They are made to function well for their intended use......So, if you find one that is exceptional sounding for audo....it is a find......The Giandel seems to be the one for NOW.....only NOW....for tomorrow it may be tossed out for the SUPER DUPER lastest one......This game has just begun.

"My musical experience and knowledge exceed anyone you have ever met in your long life" Wow, someones ego is out of control. How do you know this? And WHY would you state that? Do you want to be seen as super important and all knowledgable? When you really love yourself deeply.....you also deeply love everyone. You would never try to make your self superior to others.....We know who is most loving....by their love. No one needs to brag that they are loving.

You are so beautiful.....you never need to brag or put on a display....you simply be yourself.....and the "yourself" that is real wants to always be of service and love everyone because that is what is REAL and gives the most happiness to everyone.

"I’ve learned that people will forget what you said, people will forget what you did, but people will never forget how you made them feel.”~ Maya Angelou

Please, love one another.....make someone FEEL good.

A beautiful woman was talking to me as I was leaving the property here a couple of days ago. She called me "sweetheart".........As I drove out in the street, I was glowing.....I kept saying to my self....."she called me sweetheart".........she made me feel good. So, my sweethearts....have a great day, and a great life...YOU are loved.....pass it on.

ricevs,

Thanks for links to Oeno's comments.  He has good musical insights and describes the benefits of his Giandel system in a useful way.

You will want to get a Giandel for yourself, maybe a smaller 2200 if that's what you can afford.  Go to Oeno's place, and A/B it with his Giandel 5000, using his same batteries.  Then put Wonder caps on yours, and you both can listen and evaluate.  But it might be risky to take his 5000 and modify it, since he is very happy at present, and there is a chance that he has slightly different sonic tastes than you.

You want to know how a 2200 watter sounds versus the 5000 watter?.....you buy them both and compare.....You have the credit to do that ($1300)?  or are you as money poor as me? (remembering that you can get your money back on either or both).

I only mentioned that you get the G 2200 so you can learn firsthand what the benefits of your mods (Wonder Caps and possible other tricks you have) would be for the G 2200.  If Oeno is intrigued with your mods, he might be interested in your mods for his G 5000.

I have plenty of money, but am prudent because high end audio is a minefield of many ways to financial ruin.  Even after careful research, it still is a minefield unless you listen for yourself through a friend with mutual interests.  You listen in each others' systems, and he lets you borrow an item for a week so you finally learn the truth in your own system.

Don't count on money back guarantees from a company on the other side of the world.  I still can't tell the country of manufacture for Giandel.  It is a tough economy with many delays due to supply chain disruptions.  I go into this project with the possible outcome that I lose all money spent, at best 50% assuming someone from this tiny audience will buy my stuff, but then he will know that I don't like it.  I can afford to lose $1-3K on all this. So I get the best known system (A-time/Giandel 5000) at this point.
