    PV System Backfeeding to Utility thru padmounted transformer

    I have a PV grid-tied system at 480/277volt tied to the service entrance switchgear. The secondary of the pad mounted transformer will be 480/277volt solidly grounded system. What configuration the transformer needs to be at the primary? what concerns I have to worry about when backfeeding?
