3000W Inverter Circuit design questions

Inverter Circuit

hi Guys

A few questions...

how will it be possible to build a 3000W inverter circuit?
What is the most desirable input voltage?
Can i build a circuit with a higher input voltage, and just convert it from DC to AC?

and then:
Will it be possible to run this circuit continuously?ie 24 Hours?
How will i dissipate the heat generated?will a normal PC circuit board fan work?

Regards

Inverter Circuit

You can build an Inverter for 3000W no doubt.

For 12 V you will 250amp current assuming your circuit is 100% efficient.

Sure you can build with a higher input voltage, but it comes with a lot of cons.

And you cannot cool it with a PC circuit fan. You might need to cool it using oil.

Is there somewhere i can obtain such a circuit diagram??
