Circuit for sync inveter

[South Easter]

Can someone help with a relatively simple circuit for a grid tied inverter?

The idea is to be able to use power from alternative sources to supplement the utility power in a house.  It would plug into a wall socket, and supply a max of 15A.

TIA,

I don't think there is a simple circuit for a grid tie inverter.

If you can find one you had better not tell the utility that you intend to use it. These things are far from simple and virtually impossible for a private individual to get approval for.
