1. A wind turbine comprising, a tower, a nacelle mounted on the tower, and a rotor for harvesting wind energy by rotation of the rotor about a rotor axis extending in a vertical center plane, the nacelle comprising:
a main unit housing a rotor-supporting assembly forming a load path from the rotor to the tower, and
a first auxiliary unit attached to main unit on a first side of the center plane, and
a second auxiliary unit attached to the main unit on a second side of the center plane, the second side being opposite the first side of the center plane,
wherein each of the first and second auxiliary units houses a first operative component and a second operative component, the first operative component and the second operative component being parts of a power conversion assembly,
wherein the first operative component and the second operative component in the first auxiliary unit are respectively the same as the first operative component and the second operative component in the second auxiliary unit,
wherein the first operative component in the first auxiliary unit and the first operative component in the second auxiliary unit have the same distance to the vertical center plane, and
wherein the second operative component in the first auxiliary unit and the second operative component in the second auxiliary unit have different distances to the vertical center plane.
