Abstract: Enclosures having reconfigurable compartments for routing wiring used to monitor photovoltaic system output are described. In an example, an enclosure includes a housing around a circuitry bay and a wiring bay, and the wiring bay contains movable shrouds and/or partitions to divide the wiring bay into several reconfigurable wiring compartments. High-voltage wiring and low-voltage wiring may be routed through the wiring compartments, and the shrouds and/or partitions may physically and electrically isolate the high-voltage wiring from the low-voltage wiring. A tray disposed in the circuitry bay and include antenna mounts that extend into the wiring bay to isolate antennas mounted on the antenna mounts from electromagnetic interference from electronic components within the circuitry bay.

Abstract: Systems, processes, and manufactures are provided that employ a casing associated with an electrical component to provide some, most, substantially all or all electrical insulative protection necessary for the electrical component. This casing may be further employed with potting or other materials to supplement and add additional or different protections for the component. These additional protections can include additional insulative resistance, thermal protection, moisture protection and other buffers to and from the environment.

Abstract: A riser retention apparatus includes a board. A component connector is mounted to the board. A support frame is coupled to the board adjacent the component connector and extends from the board. A riser guide is located on the support frame and operable to engage a riser and guide a riser connector on the riser toward the component connector. A riser retention member is operable to couple to the support frame to provide a retaining force to a riser in order to retain the riser connector in engagement with the component connector. A riser including a plurality of components coupled to it may be coupled to the component connector and the support frame and riser retention member may be used to support the riser and retain the riser in the component connector.

Abstract: A door panel system and method according to which a door panel is coupled to a member such as a chassis. A door panel is coupled to the chassis and is automatically rotated relative to the chassis.
