Combiner boxes are used to bring together series strings of modules with parallel connections, to transition to larger or different wire types and to serve as an equipment disconnect for the PV source. A combiner box with 3 or more parallel strings should also include Overcurrent protection devices as a short circuit could result in all of the current of the other series strings feed through the string with the fault. A combiner box could be as simple as a basic junction box with wire nuts to a pre-manufactured box with multiple overcurrent protection devices and a remote disconnection switch.
Combiner boxes are typically installed outdoors and should therefore be designed to properly withstand the conditions in which they will be installed - see weather ratings for more information. For a combiner box to be properly watertight, it is also necessary that the proper connectors are used.
