I got pretty excited about plans for a 1200 watt inverter, then I saw that it was square wave, and used a transformer that probably weighs a couple Kg. Switch-mode design comes to mind, but that is a fairly complicated subject that I don't know a lot about. I am thinking about trying a "Class-D" style design, a pulse-width modulated switcher that doesn't require a large transformer.
