L'article est conforme à la description, le produit se dévisse, le fusible est fourni et s'insère facilement à l'intérieur.

As described, quick delivery. Thank you

A fuse is needed depending upon how you set up your solar panels. I got this as am looking to expand my setup.This is a well build fuse holder, each end can unscrew and the tube middle part can come right off to make it super easy to replace the fuse (if ever needed). The ends each have a washer for connecting to the middle tube part so it's water proof inside.This uses MC4 type connections so it can just be put inline with your solar wires (near the panels).

INITIAL OBSERVATIONSThis 15 amp PV fuse and holder appeared to engage properly with the mating connectors of my temporary/emergency solar panel, as shown in the relevant photo below. The two end sections appear to seal appropriately with the middle shell. This product *may* ultimately be adequate for my needs, though I’ve not finished installing the PV system, so I have no in-use-performance data.CONCERNSAs received, my ‘garden-variety’ digital volt-ohmmeter detected no difference in resistance between touching the leads to the fuse terminals and touching the leads together. Therefore, ‘decent’ electrical contact seems present between the fuse-holder terminals and fuse at room temperature. However, from an engineering standpoint, I worry about two things.• Firstly, there's no spring-loading at the contact ends of the holder to ensure good electrical contact with the fuse under all conditions. Good electrical contact depends entirely on maintaining screw-together tightening pressure (good axial load at the contacts). However, in hot weather, the plastic-body fuse-holder will expand in length more than the ceramic-body fuse (due to quite-different coefficients of thermal expansion), thereby reducing fuse-contact pressure. Enough to cause failure in hot conditions? TBD.• Secondly, the side prongs of the *as-received* fuse holder don’t mechanically grip the fuse around its circumference at all, as I’ve tried to illustrate in a second photo. If one picks up one end of the fuse holder, the fuse readily drops out.For those reasons, I strongly advise bending all side prongs at both ends of the fuse slightly inward such that they mechanically grip the fuse. See the third photo, which shows fuse-contact grip following the suggested alterations. These simple alterations will at least help to ensure good electrical contact.BOTTOM LINEPer my initial observations and judgment — which do not include observations of in-use electrical performance — I can’t in good conscience give this fuse holder (as-received) more than a ‘C’ grade: three stars. If my in-use experience subsequently warrants a different grade, I may modify this review in the future.

I am actually using two of these for peace of mind. It's likely overkill, but I placed this one in line with the negative feed, and another one from a different manufacturer in line with the positive feed. The actual solar input at my charge controller is 48V at about10A and the controller has a 15A max input spec, so I chose the 15A model for protection.The fuse fits snugly in the holder, and the holder housing fits nicely into my existing feed lines. The only noticeable difference I could find is that the small black o-rings (gaskets) in the fuse holder appears to be much thinner than that of the other manufacturer. Even so, it's likely sufficient enough to protect it from harsh weather. I have this mounted indoors, so not even a concern for me.A simple, easy to install device for added peace of mind.
