Typically with a PV installation you have multiple combinations of solar arrays all on one roof or different sections of the roof. The positive and negative leads from each array (described in the 2005 NEC as the PV source circuits) are brought into what we call a "combination box", where multiple leads of the ungrounded conductors (positive) are combined via DC breakers onto a bus bar. This bus bar will have a main lug where a larger AWG conductor takes all of the combined amperage from each array and feeds the main DC breaker typically located within the same enclosure as the inverter. The cicuit between the combination box and the inverter is referred to as the PV output circuit. 690.14(C)(1) states ....the PV disconnecting means shall be located at a readily accessible location........ Since I have a primary DC breaker for the PV output circuit located within the same enclosure as the inverter, and the inverter is located within "a readily accessible location", does the 2005 NEC allow me to mount the combination box on the roof next to the arrays??
