Abstract:
1. A junction box comprising: an outer casing configured to be mounted to a photovoltaic panel; a first chamber within the outer casing, wherein the first chamber includes a plurality of supports adapted to mount a circuit board configured to electrically convert power output from the photovoltaic panel, and wherein the outer casing includes an opening to the first chamber; a second chamber within the outer casing, wherein the outer casing includes an opening to the second chamber, and wherein the second chamber is configured to provide an electrical connection to the photovoltaic panel; a double wall adapted to separate the first chamber and the second chamber, wherein the double wall is adapted to allow for mutual separation and re-attachment of the first chamber to the second chamber so that the circuit board is replaceable without requiring disconnection of the second chamber from the photovoltaic panel, and wherein, when the circuit board is mounted in the first chamber, the circuit board in the first chamber is electrically connected to the electrical connection in the second chamber via a re-connectable bus bar, wherein portions of the bus bar are contained in the double wall; a first lid adapted to seal the opening to the first chamber; and a second lid adapted to seal the opening to the second chamber.
