Following some confusion elsewhere about the use of diodes as a means of lightning protection, perhaps a separate thread might help separate and clarify.
Generally they are wired across the DC output from the array, and the ACfeed, and provide a low resistance to PE under fault conditions.
And here's a couple of physical examples, one designed for external cabinet mounting, the other for DIN rail enclosures.
And here's a typical combinerbox, showing string fusing, SPD & associated PE wiring along with the impressiveDC disconnect.
