    Hi guys, I am new to this but i am working on a project and i could use some help.
    I am trying to design an off-grid solar PV system using grid tied inverters.
    any ideas on how to operate a gid-tied inverter off grid?

    A bit of a hijack but..

    You can't - at least the ones I know of will turn off for safety once the grid is lost.
    Imagine if Mr ElectricMan turns off the power to your street and works on the cables, your grid-tie inverter is still holding the cables live and would give him a rude wakeup call.

    edit - how rude Omarhosny, a double post.
