Junction box and solar cell array

摘要

A junction box of a solar cell array/solar module, having a plurality of solar cells connected in multiple strings and including a separate top part mechanically connected to a bottom part, and in one of the bottom and top parts, first contact elements, some being connected in the installed state to solar cells and two of which are connected to a connecting cable of the solar cell array, and in another one of the bottom and top parts, interconnected second contact elements electrically contact first contact elements in the installed state and join them are situated there, and an actuator for releasing the mechanical connection between the bottom and top parts, for completely separating the top and bottom parts and for disconnecting the contact between the first and second contact elements and a control unit assigned to the actuator at the input side for generating an actuator control signal.
