I hope that it would be useful for you.

With an inverter you will control both the active and reactive powers which implies the regulation of AC-side voltage and frequency. Howerer, with a back to back converter you will be able to control the active and reactive powers, and also the DC link voltage.  

Dear Bhargav Balbhadra,

I am afraid that answering your question is not that easy !. there are several issues to put into consideration before your decision:

these are only some of the issues, and the reason of sending this to you is to provoke the sense of searching in these issues before deciding what to do.

Dear Mohamed elgenedy

1) I am working on solar inverter which is capable of delivering real and recative power

2) converter should give +/- 15 kVARs

3) I will utilise voltage source one

4) Yes it will be front end converter

thanks for enlighting this questions, I will start my search accordingly,
