The Phoenix Contact solar line string combiner boxes are used in both small rooftop systems and large ground-mounted systems. The main tasks of the SCBs are the surge protection of the PV system, collecting strings, and looping through the protective equipotential bonding conductor for the local equipotential bonding. Further functions are optional and depend on the equipment. Examples of optional functions include protecting the strings with string fuses and disconnecting the strings via DC switch disconnections or DC fire department switches.
