I am not 100% sure but I think that there is often confusion between max
fuse and max reverse current. When you list a module you request a fuse
rating , in this case 4 A and UL will test it by applying a max reverse
current of 1.75(max fuse rating) or 7 Amps with out a fuse to insure tha
Reverse current and max series fuse are not always the same, check out this
Solar Frontier manual, pg 3:

I just did a class exercise using the upcoming sw290 for sizing conductors
and OCPD and the calculation was such that a 20 amp fuse was needed
(rounding up from Isc x 1.56). I hope that the maximum reverse current on
the spec sheet is also the maximum series fuse rating.
