It is backwards to try to convert a powerful square-wave into a sine-wave. The filter inductors and capacitors will be huge, expensive and will waste a lot of power.
Modern sine-wave inverters use Pulse-Width-Modulation with a very high switching frequency to produce a chopped sine-wave then the high frequency pulses are smoothed together with a small filter to produce a smooth powerful sine-wave.
