NOVELTY - The system has a set of positive wire lines (36) leading from photovoltaic modules. A combiner junction box (16) includes components for receiving the positive wire lines from the photovoltaic modules and combining the positive wire lines into a smaller number of positive wire lines leading from the box and toward a load i.e. distribution grip. A set of in-line fuses (60) is connected in-line to one of the positive wire lines leading from the photovoltaic modules. The fuses are positioned proximate and physically outside of the box such that the fuses are accessible without opening the box.    USE - Solar power generation system i.e. photovoltaic power generation system.    ADVANTAGE - The system removes the fuses from the box to remove a major source of heat from the box so as to increase electrical ratings i.e. Underwriters Laboratories (UL) ratings, of the box to alleviate capacity bottleneck in the system, thus raising allowed load capacity for the box. The fuses are located externally from the box to reduce minimum dimensions of the box and UL standards specify minimum bend space requirements for conductors in the box to allow sufficient room for ergonomic access by a technician for servicing components in the box, thus avoiding minimum bend space requirements for the fuses, and hence reducing minimum dimensions of the box. The system allows the externally located fuses to be accessible and serviceable for replacement or repair by the technician without opening the box, thus reducing servicing time and complexity and eliminating injury risks associating with working inside the box. The fuses can be provided in terminated wire harnesses for easy connection to an exterior of the junction boxes.    DETAILED DESCRIPTION - The box houses multi-line power distribution blocks (70), external connection interfaces (72), a disconnect switch (74) and a circuit protection/surge protection system (76) as the components of the box. INDEPENDENT CLAIMS are also included for the following:    (1) an externally-fused combiner arrangement for a solar power generation system    (2) a method for replacing or servicing a fuse in a solar power generation system.
