Photovoltaic modules connected in series and parallel to the combiner box

Each string normally consists of several solar modules connected in series. When several strings are connected in parallel, the outputs are brought into a combiner box so they can be collected and routed to the inverter, charge controller, or DC power conversion. A PV combiner box is an electrical enclosure that brings multiple solar string circuits together before the inverter or charge controller. The combiner box collects those string outputs, provides protection and switching functions, and. A solar combiner box wiring diagram shows how multiple photovoltaic (PV) strings are connected into one or more DC output circuits before going to the inverter. This wiring diagram will guide you in understanding how to properly wire a PV combiner box. [pdf]
