LC filter design for grid connected inverters

Dear all,

I am designing a single phase SPWM inverter , which is to be connected to single phase Grid . I need Filter design calculations , What should be the Land C calculation that well suits for my inverter.

Though I have referred good no.of papers which talk about filter design, many of them talk about frequency response more on . Actually I am looking for L and C calculations (formule)

Thanks in advance
