Cold cathodes are used as field emitters within a multi-spectral light source, which is flat and compact. A first set of wiring electrically connects the PV array to the inverter through a disconnect device and a second set of wiring electrically connects the inverter to the electrical interface. The Linking Application Program takes the installer through a step by step installation and linking process that ensures the maximum possible linking accuracy. The intersection extractor identifies one or more possible intersections in the one or more poses.
