Stringboxen

A string box is a collection box for DC cabling, in which the strings are secured by means of pin fuses. The string boxes provide extra protection in the event of a short circuit in the DC side, or the event of a lightning strike. With larger strings, reverse current can occur. Therefore it is necessary (according to NEN 1010) to provide solar panel installations with 3DC strings or more with fuses.
