Photovoltaic string combiner

A string combiner brings identified solar DC circuits together at a defined connection arrangement.

Drawing use: Schematic
Application: Microgrid systems
Reference family: Manufacturer

A distinction that matters

A combining connection does not replace the need to specify each circuit's protection and isolation.

Symbols

Photovoltaic generator

A photovoltaic generator represents the electrical production of PV cells or modules. On an SLD it is linked to documented series/parallel strings, DC protection and the inverter interface.

Drawing use: SLD / Schematic
Application: Microgrid systems
Reference family: IEC / Manufacturer

A distinction that matters

The PV generator is a DC generating function; the inverter produces the documented AC interface.
