04 Nov 2009 20:01 connection problem of two dc source

i have a 1000 W load and 500W PV panel. I use grid to supply my load by the aid of 280V output Partial Switcing Converter (PSC)

I want to use my PV panels and not to pay for extra energy. i have to design a grid cooperated system.

i know that i need a MPPT which has a 280V output. I don't know how to design a boost type MPPT and how to connect it to PSC after the designing a MPPT.

Assuming that; i designed a MPPT with 280V output , what must i do after. Directly connection it to PSC output? If a regulation problem occurs at output of PSC or MPPT what will do? Is there any dc to dc connection methode?
I need master's help.
Could you please help me.
Thanks.
