Hi
I would like to make 1000W capacity 230V single phase AC pure sine wave inverter.

The input will be 12 V DC.

Is it possible to make it? I need circuit digram or at least help, proper website.

Or shall I prefer to buy it commercially?

Please reply.

 

A 500W inverter itself is very complicated to build from scratch and even costlier than buying a commercial board and assembling one. If you need to build one with pure sinewave, you will mostly need to go a long way with microcontrollers and programming. Building one needs the correct rated PCB track width to handle heave currents near 90A!! And if you make a small mistake, it will be catastrophic. Better buy a board and assemble it with the transfomer and case rather than building or buying a complete inverter.
