By default, ElectricalOM treats each inverter DC input as being connected to an independent MPPT (Figure 12). However, when modelling inverters with multiple DC inputs internally paralleled onto a common DC bus, or when multiple PV strings are connected via a combiner box, users can represent this configuration using the Junction Box component, as illustrated in Figures 13–14.
