About Centralized PV box-type transformer combiner cabinet cost per megawatt

For bringing the power generated by the sun to the grid the following key components are needed: PV modules as DC power generators, DC collectors (DC combiner boxes or.

The higher power density and the number of DC inputs are mainly influencing the inverter costs.

Special cables (NSGAFÖU) connect air laid e.g. the inverters to the AC box at the rack at a maximum length of 2m or the AC box to the AC cabinet. The highly flexible, double insulated cables with copper conductors and different rubber compounds are high.

Comparing the overall cost situation between decentralized and a virtual central approach, a system price comparison is needed. To do this with a practical orientation PV system has been designed based on state-of-the-art components.

The bundling of string cables to a single connection cable inside a DC combiner box is only valid for the virtual central layout. The virtual central layout keeps the cable losses on the DC side, unlike the decentral layout. Since in general the DC generator is over.
