With the one-stage concept, the module phases' energy fed to the inputs of the SINVERT PVS CombinerBoxes is directly routed to the SINVERT PVS inverter or inverter station via one output respectively.

With the two-stage concept, the module phases are initially combined in the SINVERT PVS CombinerBoxes (first stage). The outputs of these SINVERT PVS CombinerBoxes are then routed to further SINVERT PVS CombinerBoxes (second stage). The outputs of the second-stage SINVERT PVS CombinerBoxes are subsequently routed to the inputs of the SINVERT PVS inverters or inverter stations. The advantage of this two-stage concept lies in the minimized power loss due to the increased cable cross-sections.
