I know it isn't that crazy

I can barely tie my shoes without some help from you guys

and they got me on as a guru on here

I guess it goes off being a blabber box instead of knowledge

The more I read these forms and more I'm impressed you guys work together and do some amazing things

I'm still having a very hard time finding things on this form

if you had a link to your inverter that you're talkin about I would love to see it

And Tinker did you see the Caps I put on My Little China board

It came with 470 UF two of them

I replace them with 18000 UF

had to use 10 gauge wire because I couldn't get them right against the board

I plan on changing that later maybe

I did build up all the tracks also

I soldered in either or 12 or 14 gauge wire into the track

Some people that are newer on here

Thanks I build this on my own

but I have someone holding hand the whole way

Thanks everyone I really appreciate it

I have found out in life that is if you have the right instructor telling you how to do it you can do most of anything

So anytime you see something of mine up and running just remember that

It's not because of my knowledge on this stuff because I have none

Good instructors made it happen

Thanks again everyone

You need to try harder looking Ben, its all here somewhere

Looking beats watching TV

Try "inverter No.4" topic for more ideas. Just scroll down on the electronic topic pages until you find it, then click on it and read from page 1 to whatever the last one is.
Get somebody who is more familiar with forums to show you how to navigate the pages if you get stuck. This is better shown one to one rather than cross the globe.
That should keep you busy for a while

.

PS. Having a "good instructor" is only half what's required to learn. The other half has to come from yourself with a willingness to investigate on your own to find out how things work. This is much easier these days with computers and the internet. When I was an apprentice there were definitely no 'holding hand' instructions. We learned most the 'hard way' but that information sticks much better than spoon fed stuff.Edited by Tinker 2019-06-14

Haven't watched any TV for over a year now

I spend most of all my spare time on here I know it doesn't show

I have to read something about 500 times for it to finally sink in

When I'm having really bad days I can watch a movie 10 times and every time

I'll be watching it for the very first time

This is no one else's fault but my own

But if you consider this information

I might not be quite as puzzling sometimes

Thanks for the advice tinker been reading a lot about your shenanigans lately

Very very impressed

Completed inverter thoughts

200 amp breaker box is what I installed it in

With over 50 lb Transformer this box ain't rigid enough

When lifting it up the box bins diagonally

Of course it'll be fine I'll have it mounted to a piece of plywood

If I was going to do it over again I would find something more rigid

Now to the inverter board itself

If I had it to do over again I would get a board with no more than 16 mosfets

Just my opinion but I think 24 is overkill and just ads more components to go bad or too fell

There are eight capacitors on this board each capacitor is 1500 UF I think this is way too low of a value

With the four mosfet little China board inverter I made (with the help of poida the great) it starts enormous loads

But it has a almost 30 lb Transformer in it and it also has two18000 UF capacitors

That's 36000uf compared to 12000 with the 24 mosfet board

One of the greats on here not saying any names (warpspeed) has said on more than one occasion that the layout of the inverter is very important

I would definitely agree with that

If I was to do it over again I would lay out every component and figure out the best configuration before I even started putting it together

So to wrap this all up with my very little experience

very little knowledge

I would advise someone it was looking to build an inverter

to use the biggest most efficient Transformer that they could get their hands on

The biggest uf capacitors that are rated for an inverter that they could get their hands

Pay very close attention to the layout

the very most important thing of all

Is do your very best to get one of the greats on here to Mentor you

keep in mind you got to be willing to listen

This project is officially over

all the testing went very well

I wasn't able here at the house to get the fans to kick on

the highest temperature I could get from the heat sinks was 84 degrees Fahrenheit

Tested with a fluke 561 IR thermometer

The bi-metal temperature switches don't turn on until 104 degrees Fahrenheit they kick back off at 81 degrees Fahrenheit

63 amps on the DC side was the highest I was able 2 sustained for more than 20 minutes from lack of batteries

I have done short bursts of 120 amps but not enough batteries sustain it

I still haven't checked the sine Wave have no way to

I will be putting an ad in the paper trying to find somebody that's willing to come check it out for me

I cannot afford a scope at this time so that's my only hope

Everything that I could do here at the house has been done

so now it's going to the RV wish me luck

By the way the little for mosfet China inverter has ran everything that I wanted it to run at the bus so far

I will be giving it to my dad and installing a few solar panels for him for when the electric goes out

If you've made it this far I think you for your interest in my projects

And I appreciate all of the wisdom from everyone on this site

That little to wired device you see in the first picture

It is a switch that is normally open until the temperature gets to 40 degrees Celsius

then it closes I will be using it to turn the top case fan on and off

You can get these in any temperature range

I've not seen that sort of temperature switch, can you provide a link for it?
