I came across a schematic of a reverse engineered 12V - 120V AC Power Inverter. So I started to make the "ONE BAD A$$ POWER INVERTER.

After looking over the schematic of a reverse engineered power inverter I thought to myself "Self this is not that complicated". So I set about making my own BAD A$$ POWER INVERTER.
My Goals are as follows.
1. Pretty Easy to build with normal parts
2. Expandable
3. Be able to deliver roughly 500 - 5000 Watts depending on how many transformers are installed.
6. Power my whole conversion van :)
I found these extruded aluminium parts at a scrap yard of all places. I paid $10 for all 4. I placed the spray can in the picture for size comparison.
Basically the only thing holding me up on this project is -
1. Some kind of cool box, cabinet or housing to put this in.
2. Winding the transformers. They are 6 turns center tapped primary and 52 turns secondary.
3. Getting the IRF1404 Mosfets, Fuses, Fast Diodes and some capacitors.
4. Working on my Radio restoration lately...
Here are the 2 pcb's I built (I was lucky and used my buddies CNC machine to make them). The reason I built 2 separate PCB'S is because the smaller one can be used for other projects ( I made 2 extra pcb's for another project). You can build all the stuff on one PCB if you like or point to point. I have the eagle files too if someone wants to have pcb's made or make the files better.
Parts is Parts (Notice my collection of EDT-49 Transformers CUE -EVIL LAUGH-)
PCB with SMPS and lm324 circuit.
PCB for 60HZ driver.

These are some STOUT Mosfets 100amp 500v and something like 2000 watts dissipation.
The schematics I based my inverter on I found here -

I did not deviate from the design except with my choice of Mosfets , Diodes and Transformers.
