Outbound-energy-flow qualifier

An outbound-energy qualifier identifies energy leaving the represented device or boundary. The arrow’s meaning is relative to a chosen device or system boundary. A converter may export energy through one port while consuming energy at another.

Power converter / inverter

A power converter changes electrical power between the circuit forms specified for its application. In a battery energy storage system, a power conversion system commonly provides the interface between DC storage and an AC system. Direction of power flow and operating capabilities are product-specific.

Application: Microgrid systems
Reference family: IEC / IEEE / ANSI

A distinction that matters

Inverter, converter and PCS can denote different equipment boundaries. Define what is included in the represented assembly.
