An electrical assembly may include an enclosure having a base portion to attach the enclosure to a panel and a heat dissipating portion opposite the base portion, a circuit board having a first thermal interface on a first side of the board, a second thermal interface on a second side of the board, and a thermally conductive portion to provide enhanced thermal conduction between the first thermal interface and the second thermal interface, a power electronic device having a thermal interface coupled to the first thermal interface of the circuit board, a heat spreader arranged to transfer heat to the heat dissipating portion of the enclosure, and a thermally conductive pad coupled between the second thermal interface of the circuit board and the heat spreader.

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 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.
