Hi all,
we are in a process of developing a 1MW grid tied outdoor solar inverter.
output voltage will be 400 Vac . Input will vary from 550-900 Vdc.

Please let me know what kind of SPD should be placed in DC and AC sides with their rating .
let me know what rating of SPD to be used.

I have attached the single line diagram of system also.

    Not really a question for a forum, ask your engineer! Are you independent or is this for an electric company? We mostly deal with home systems.
    Home system 4000 watt (Evergreen) array standing, with 2 Midnite Classic Lites,  Midnite E-panel, Magnum MS4024, Prosine 1800(now backup) and Exeltech 1100(former backup...lol), 660 ah 24v Forklift battery(now 10 years old). Off grid for 20 years (if I include 8 months on a bicycle).
    - Assorted other systems, pieces and to many panels in the closet to not do more projects.

    A system that size requires a licensed electrical engineer. He should be advising you on these matters.
