I've got a 6S2P array with 12 445w Panels. The panels have an ISC of over 10a and a maximum series fuse of 20a. I've seen several people on this forum say you don't need an inline fuse with 2P but i'm not sure why.
Why would 2P not require an inline fuse? Does it have something to do with the way the current can travel between those strings?
If I did add inline fuses on the positive lines for both strings would it give me loss or simply no protection at all? Is there a reason I wouldn't want to do that?
*By inline fuse i'm referring to the type that are labeled as MC4 fuse holders with a 20a fuse in them them, positioned just before the branch connection on the two strings.
