A less expensive building wire can be installed on the other side of the junction or combiner box. THWN-2 and XHHW-2, for example, can be used for the PV output circuit, but should always run in conduit when used outdoors as they’re not UV-resistant. Both wire types can withstand high heat and wet conditions that could result from condensation.

What Is the Difference Between Line and Load Wiring? The incoming feed from the utility company comes into the line side of an electric meter. It leaves the meter from the load side and then feeds the line side of a disconnect or electrical service panel.The service panel also has line and load connections—the line feeds the main breaker in the panel, while the individual .The following wiring method and enclosures that contain PV power source conductors shall be marked with the wording “Photovoltaic Power Source” by means of permanently affixed labels or other approved permanent marking: (1) Exposed raceways, cable trays, and other wiring methods (2) Covers or enclosures of pull boxes and junction boxes (3 .
This distance is about 3 feet. However, those #6 wires would only be protected by a 400 amp fused disconnect so it doesn't seem right or safe. OTOH, the same situation exists with the main service panel which is 200 amps. The wire going from the junction box to the main panel is 2/0, whereas the wire feeding the junction box is 350. Through the exceptional efforts of the members of NFPA NEC Code-Making Panel 4 working with the proposals and comments that were submitted for the 2014 Code, significant changes have been made to Section 705.12(D), Load Side Connections for Utility-interactive PV Inverters. These changes will allow better understanding of the requirements for load-side .
