Re-combiner box of photovoltaic system

A photovoltaic system having multiple fuses, comprising:

• combiner boxes respectively coupled to groups of photovoltaic strings, each of the combiner boxes being configured to aggregate the electric current generated by the corresponding group of the photovoltaic strings into multiple poles;
• and
• a re-combiner box electrically disposed downstream from the combiner boxes, the re-combiner box comprising:
• a rotor configured to occupy at least first and second rotational angles;
• a disconnect unit comprising a plurality of interrupter housings respectively configured to connect at least one of the multiple poles with at least one of the multiple fuses in accordance with a rotational angle of the rotor, at least one of the plurality of the interrupter housings being mutually connectable;
• a transmission unit disposed and configured to electrically combine the multiple poles into a lesser number of the multiple poles such that respective amperages of the combined poles are additive;
• a housing sized to house the rotor, the disconnect unit and the transmission unit;
• and
• an actuator arm disposed at the exterior of the housing and configured to be selectively actuated to cause the rotor to occupy the at least one of the rotational angles.

A method of assembling a re-combiner box of a photovoltaic system, the method comprising:

• assembling individual interrupter housings;
• forming re-combiner box housings of varying widths;
• forming rotors of varying lengths;
• receiving an order for a re-combiner box configured to serve a given number of poles in the photovoltaic system;
• and
• assembling the re-combiner box with the given number of interrupter housings, a selected one of the re-combiner box housings selected as having a width in accordance with the given number of the interrupter housings and a selected one of the rotors selected as having a length in accordance with the given number of the interrupter housings.
