How to Properly Fuse a Solar Photovoltaic System
To properly fuse a solar system, you must install DC-rated fuses sized at 156% of the array''s short-circuit current (Isc × 1.56) in the positive conductors of parallel-connected strings,

Maximum Series Fuse Rating
Maximum series fuse rating 10A means, if the panel suffers a short, it can safely handle no more than 10A getting dumped into it, otherwise could overheat a wire/trace and present a fire
