[500W sine wave inverter design]

I know it is easier to build a square wave inverter but I heard that they don't drive power tools and other motors very well is this true.

[500W sine wave inverter design]

Hi I am new to this forum so please tell me if this is in the wrong place.
I would like to build a 12v dc - 230v ac sine wave inverter capable of proving 500W
of power into various loads including Florescent lights and power tools. short circuit protection and battry low cut off would be nice but not essential.
Any help would be appreciated and schematics and pcb's are welcomed thanks inadvance Hell Boy
