The Solarline string combiner boxes (SCBs) are used in large ground-mounted systems. The main tasks of the SCBs are to protect the photovoltaic system against surge voltage, to collect and protect PV strings with string fuses, and to disconnect the photovoltaic system from the power source.
Further functions are optional and depend on the equipment.
An example of optional functions is string monitoring, which can be used to measure and monitor the string currents and the system voltage.
