Abstract
A lead assembly includes at plurality of drop line joined to a feeder cable at joints each having a compression lug that is preferably surrounded by undermolding and overmolding. In use, each drop line is connected to a solar array, and the feeder cable is connected to an inverter. In this manner a plurality of solar arrays are electrically coupled together, with a common feeder cable connecting them all to the inverter. A system of the present invention doesn't require a combiner box which is conventionally employed directly upstream of the inverter.
Claims24
A lead assembly for electrically coupling one or more drop lines to a feeder cable, the lead assembly comprising:
- a joint where a section of the feeder cable and a section of the one or more drop lines can be electrically coupled at a nexus, the joint including the section of the feeder cable and the section of the one or more drop lines;
- and
- a monolithic mold that encapsulates the nexus, the monolithic mold further comprising:
- a feeder pathway extending completely through the monolithic mold and configured to allow the feeder cable to extend completely through the monolithic mold;
- and
- one or more drop line pathways that each extend at least partially through the monolithic mold, and each configured to allow one of the one or more drop lines to extend at least partially through the monolithic mold;
- wherein:
- each of the one or more drop lines are configured to be capable of receiving electrical power from a plurality of solar panels for combination at the nexus to the feeder cable;
- one of the one or more drop lines includes a section of exposed wire at the nexus;
- the feeder cable includes a section of exposed wire at the nexus;
- and
- at least a portion of the section of exposed wire of the drop line is parallel to at least a portion of the section of exposed wire of the feeder cable;
- wherein the one or more drop line pathways and the feeder pathway extend parallel to one another within the nexus, and the monolithic mold has distinct openings at ends of the feeder pathway and one or more drop line pathways through which the one or more drop lines and the feeder cable exit the monolithic mold.

A lead assembly comprising:
- a joint where a section of a feeder cable and a section of each of two drop lines can be electrically coupled at a nexus, each of the two drop lines connected to a wire harness and configured to receive power from a plurality of solar panels;
- a primary mold that encapsulates the nexus so as to substantially seal the nexus from external environmental conditions, the primary mold further comprising:
- a feeder pathway configured to allow the feeder cable to extend completely through the primary mold;
- and
- two drop line pathways that are each configured to allow the two drop lines to extend at least partially through the primary mold, the two drop line pathways including a first drop line pathway and a second drop line pathway;
- wherein at least a portion of the first drop line pathway is parallel to at least a portion of the feeder pathway;
- and wherein at least a portion of the first drop line pathway and at least a portion of the second drop line pathway extend in opposite directions along a longitudinal axis that is parallel to a longitudinal axis of the feeder pathway.

- a mold structure that encapsulates the nexus so as to substantially seal the nexus from external environmental conditions, the mold structure comprising:
- a feeder pathway configured to allow the feeder cable to extend completely through the mold structure;
- and
- a drop line cable pathway configured to allow the drop line cable to extend completely through the mold structure, the drop line cable pathway including a first drop line pathway configured to allow the first drop line to extend partially through the mold structure and a second drop line pathway configured to allow the second drop line to extend partially through the mold structure;
- wherein at least a portion of the drop line cable pathway is parallel to at least a portion of the feeder pathway;
- and wherein at least a portion of the first drop line pathway and at least a portion of the second drop line pathway extend in opposite directions along a longitudinal axis that is parallel to a longitudinal axis of the feeder pathway.
