Decently well documented inverter system, 2 kW, using transformers:
- Disadvantage: about 70-80% efficient; appears that non-solid state inverters are less efficient than solid state.
- Commercial, solid-state inverters are 90-95% efficient (ex., [2])
Another, smaller-power, less documented example:

I found this site, where they propose to use modified transformers from old microwave ovens, you’d need about 10 broken micros’ and 20 N-type power MOSFET’s for a 9kw unit.
