1. A wind turbine nacelle configured for mounting on a wind turbine tower and housing a rotor-supporting assembly supporting a rotor, the nacelle further housing a power conversion assembly, the nacelle comprising:
a main unit arranged to be connected to the wind turbine tower and housing the rotor-supporting assembly, and
at least one auxiliary unit housing an operative component forming part of the power conversion assembly, the at least one auxiliary unit including a roof part
wherein the main unit and the auxiliary unit are separate units configured to be connected by a unit fixation structure at an interface, and
wherein the at least one auxiliary unit has a first height defined by a greatest height of the roof part in an assembled configuration and a second height defined by a greatest height of the roof part in a transportation configuration, the first height being higher than the second height.
