An apparatus of a junction box component housed in a junction box and designed to be coupled to a power generator. The junction box component may include one or more bypass mechanisms configured to bypass one or more substrings of the power generator in a case of malfunction or mismatch between the substring and the remainder of the power generators. The one or more bypass mechanisms may generate heat which may be transferred out of the junction box. The junction box component may be designed to conduct the heat towards the base of the junction box and/or the cover of the junction box. A heat dissipation mechanism may be mounted on the base and/or the cover. A bypass mechanism may bypass the entire power generator.

A cooling device includes a heat pipe connected to the semiconductor chip, a fan for cooling a heat radiating portion of the heat pipe, a temperature sensor for measuring a temperature around the device, and a control unit for controlling the fan. When the temperature measured by the temperature sensor is higher than a reference temperature, the control unit causes the fan to operate at a normal rotation speed, and when the temperature measured by the temperature sensor is not higher than the reference temperature, the control unit stops the rotation of the fan or causes the fan to rotate at a rotation speed equal to or lower than the normal rotation speed.

The alternating current cabinet, the communication cabinet, and the power distribution cabinet are all arranged opposite to the inverter cabinet. The direct current cabinet is arranged on a third side of the box, and the direct current cabinet is arranged on a same side of the inverter cabinet and the alternating current cabinet.

An apparatus for mechanically coupling a power conditioner to a photovoltaic (PV) module frame. In one embodiment, the apparatus comprises: a bracket, adapted for mechanically coupling the power conditioner to the PV module frame, comprising at least one inner-flange tab and at least one outer-flange tab for trapping a flange of the PV module frame between them; and at least one self-locking mounting structure for locking the bracket to the PV module frame without requiring any holes in the PV module frame.

A junction box used for making electrical connections to a photovoltaic panel. The junction box has two chambers including a first chamber and a second chamber and a wall common to and separating both chambers. The wall may be adapted to have an electrical connection therethrough. The two lids are adapted to seal respectively the two chambers. The two lids are on opposite sides of the junction box relative to the photovoltaic panel. The two lids may be attachable using different sealing processes to a different level of hermeticity. The first chamber may be adapted to receive a circuit board for electrical power conversion. The junction box may include supports for mounting a printed circuit board in the first chamber. The second chamber is configured for electrical connection to the photovoltaic panel. A metal heat sink may be bonded inside the first chamber.
