Hello from Wv


Recommended Posts

I am ben been happily married for many years I have 3 boys 23 13 6

I love this kind of stuff nice of Sid and Sean to make a place for me to babble nonsense 

I am not off grid but hope to be soon

I had been tinkering with building eg002 inverters and they are fun 

Now I have moved on to the top of the line 

I have what I think may be the upgrade kit wifi and control board 

I have them installed in a PJ case

I have ran many different diy trannys on this set up

It is a beast!!!

I haven't blowed it up yet and I don't think I ever will

The GS wifi and control board don't heat up on one bank of mosfets like the PJ control board dose 

Pj mosfet driver board is week it drives the mosfets at different voltages and is prone to blow up

The GS control board drives the mosfets all at same voltage no voltage drop

It has 8 amps to keep them fully on or fully off so less energy wasted by hot mosfets 

Sid got the idle current very low also

I have hooked up trannys with low side windings as low as 25volts and as high as 32volts 

From 20 pound trannys to 70 pound trannys

I didn't test the 25 volt much but I will soon 

I will also be testing a 20k tranny as soon as I get time to wind it thanks to some really good people 

I have already started on it 

I have beat the GS stuff to death  on purpose trying to kill it even accidentally done a few really stupid things 

It refuses to die but I haven't gave up I will have heat in my shed soon and will continue to torture the GS 

I use msb 60 amp charge controllers

I have lots of 330 watt solar panels

I have around 3000 watts hooked up 3 s 3p now

Will be going with 2s 4p on 6 charge controllers soon around 16 thousand watts

That all I have the charge controls for so far

I have 8 150 amp hour agm batteries but looking for a good deal on more

I built a 50 amp 48 volt 240volt power  supply

i use it with solar  and batteries when testing

I have another power supply mostly built that is a lot bigger i still need high amp rectifier

Hope to learn more and maybe get a cap to blow and stick in the wall some day

Sean got me all excited talking about it but I think it may be like a honest politician

Hopefully I get to do some more tinkering soon if so I will take pics and videos 

Sorry so short everyone have blessed day

Ripley ravenswood area 

Sean the biggest one is to TRY to blow up some genetry solar stuff

Wish me luck 

It will be while I am unusually very bussy 

When I get some free time I will install my DIY heater in my shop and get back at it God willing

Do I know you glen have you been to my house a few times

Hello, Ben this is BigBOB and i live in va. I am researching winding my own transformers and I want to know what tape wound material you are using. I am trying to

find a supplier of the material and I have a friend that winds transformers but mainly does 60Hz transformer with E I Laminations. well when you get time please reply. Thanks again BigBOB

Sorry I just seen your question 

I have unwound cores to make bigger cores 

I think the metal losses some of its temper when doing this from the bending 

The ones I have done seem to have higher idle current but nothing crazy 

I am thinking about getting rid of one I have done if so do you want first dibs  

I think it is around 7 in wide and 5 in tall I can check if you want me to

You would have to pay shipping and let me know how well it does in a inverter shipping would be between 25 to 35 dollars I'd think of it's any more than that the wife will cover it

It can collect dust on my shelf as good as yours but i would get much joy giving it to you

I would want your word that you would  try it out in a inverter 

If for some reason you couldn't you would ship it back to me or you get the info for me that I need

If you don't feel comfortable giving your word I will make time to try it before I ship it to you

Curiosity kills me two brain cells will never stop if I don't find out how it does 

Besides that I would be happy if you use it or sold it and got alot for it or just a few needed bucks 

Please forgive me and understand this is just curiosity not strings attached 

I think that the little bit higher idle when plugged in to 120 outlet will make little difference when installed in a inverter 

Wife and I was guessing when winding it  it would do at the very least 2000watts  for a 24/7 full throttle  rating

But we was hoping for over 3000 watt or more

Of course the shorter the Full Throttle run time the higher the wattage that can be run without it getting to hot

All of the hard and time-consuming work is already done on it

In 15 minutes you can have the low side wound ready to use 

if you use a single big wire like i do and most the pros do on thebackshed.com 

Make sure the single big wire is easy to bend if not it will be a wrestling match even if you use a rubber mallet

The wife and I wound the high side (120 volt) with a little over 2mm square not round wire

Even though the wire was enameled wire we painted it with a few coats of high dollar tranny coil paint before winding it

The core was epoxyed and Transformer taped before the wire was wound

We was careful to make sure the wires was spaced out evenly and didn't touch as much as possible (we knew it dosen't matter if they touch)

As we wound it we painted it with the same epoxy 

After every layer we added tranny tape and a few thick coats of epoxy 

We called it our forever tranny we wound it to last forever!!

We wanted a completely silent tranny no vibrating that would last a few hundred years

There was way to much hard work and time put into it 

Your buddy will tell you the same we over done to a stupid level 

I don't think there is enough hole left for adding another 120 volt winding and the low side winding

So you will likely be stuck without 240 volts I could be wrong haven't looked at it for a year or so


But as far as metal goes the lowest carbon (soft) is what to look for 

Cut it in strips heat treat it to glowing orange and white looking 

People in Pakistan's and other countries like Pakistan do it all the time

If you look hard enough on YouTube you can find a few videos

They mainly use them for audio amplifiers

And they all say don't use a galvanized metal

The translation I get from what they say is gutter metal or any other low carbon metal like what comes in sheets to fix body's of cars

If you cannot find this information or videos let me know and I will try to find it again for you

I have texted a few of these people from other countries and they freely share the info 

If you have problems I can try to  find where they have answered me back before

I can't remember for sure but I think you let it cool off slowly

What you're trying to do is to make the metal highly magnetic but lose that magnetism as fast as possible

So if you put a magnet to it you want it to stick but as soon as you remove the magnet you don't want the metal to remain magnetic

They called these properties soft 

When heat treatment you want all of it to be even temp 

If you get this wrong the core will have spots that heat quicker 

 And or low electrical resistance causing higher losses do to eddy currents 

You want you're core material to have as much electrical resistance as possible

This can be tested with a multimeter after heat treatment

When looked at under a microscope a properly heat-treated core will look like a bunch of dandruff pressed together

This makes the core have a higher electrical resistance 

Not a single piece of metal but a bunch of teeny tiny all together

 very thin tape like and made up of tiny microscopic pieces makes for a voltage to flow through your core material 

It has to be a metal that a magnet will stick to and hard or impossible to keep magnetized

The inverters mosfets flip the polarity of the battery

so one low side leg will be positive going into your Transformer the other negative

Then your mosfets flip the polarity the one that was positive will now be negative and negative positive 

This happens 60 times a second here in the United States 60 hertz

So if you're core metal stayed magnetized you would be fighting against this flipping

Pmw means after Mini small pulses give you all the  volts needed to make  the top of a sine wave then it flips polarity and gives you all volts needed to make  the bottom of the sine wave

These pulses for a example stay on long enough to raise the voltage to 1 volt off on 2 volts off on 3 volts and so on until all needed voltages for the top side of sine wave are done the the polarity flips and dose same for the bottom of sine wave 60 times a second 

When you are using a higher wattage it has higher resistance  each one of these countless off and on have to stay on longer to raise the voltage  crazy is it not

If the plus and minus was only flipped and turned on you will have a square wave 

I think really thin 304 stainless steel the kind that is used 4 fancy refrigerators would work very well

But it must be worked a bunch at low temperature to make it have the magnetic properties needed

I have always wanted to test my idea but could be a big failure

Whatever metal you use the thinner it is and more tape like in thickness the better

The amount of carbon in Steel can be removed from the heat treatment

so you're likely to do well with about any really thin iron sheet metal that is easy to weld and has no additives except silica 

I have wound many simple NOT grain orientated dirt cheap cores that do great and have low idle current 

I have read a few times that people in the past have used soft iron bailing wire

The air gaps in between wire makes for a bigger core with no benefit 

Tesla didn't have special metal for his motors and transformers 

What a poorly written book lol

Have a blessed day

Thanks How do i pay you Ben ?
