Combiner boxes Suitable for PV system, equipped with a surge protector and isolator fuses,provid-ing isolation, leakage and grounding protection. link PV inverters and PV arrays, combining the output of a large number of strings to improve PV performance.
These are used to allow the parallel connection of several strings of PV modules or to enable large or armoured cables to be connected from the PV array to charge controller or inverter location so minimising voltage & power losses. Since the PV array cannot be switched off these junction boxes must be labelled as 'PV Array Junction Box - Danger, contains live parts during daylight'.
These boxes can also contain string fuses which provide a means to isolate the PV strings. String fuses must be provided for all arrays formed of N parallel strings, where (N-1) x Isc (module short circuit current) is greater than the module maximum series fuse rating. String fuses are required in both positive and negative legs of the string cabling.
