Is it possible to make somehow a wireframe render if all parts of the model separated? I dont wanna join them because its too much and all of them have different modifiers and parented to different empties

Take the Wireframe Modifier.

Give one part the Modifier, then select your parts, last one with the Modifier and STRG+L (Modifiers)

You can use Wire type material (not Surface).
Addon works atleast Blender 2.77
