Abstract: A fail proof electrical connector apparatus offers a unique structure for solar photovoltaic (PV) system installations. The apparatus includes a compact connector enclosure that can be installed at flexible locations of a solar module. The tabs of the connector enclosure connect to various solar cells of the module. The insertion pins of the tabs are mounted inside plugs of a pin connector, which connects to a cable. The cable comprises a one-plug end and a multiple-plug end with a wire connecting both. Of the two or more plugs of the multiple-plug end, only one active plug is electrically connected to the wire. The cable is connected to the module with the active plug being inserted to a center plug of the pin connector, and the one-plug end connected to an outer plug of the pin connector of an adjacent module, thus, achieving fail proof, reliable installations while saving labor hours.
