Power converter / inverter

What it represents

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.

The drawing should label the AC and DC interfaces and identify switching, protection and controls separately. A generic converter box does not establish grid-forming, grid-following, island operation or export capability. Those behaviours require the selected product and system documentation.

How to read it

• Read the AC/DC interface labels before following power flow.
• Identify the selected operating capabilities from the product and system documentation.

Information to show or reference

• Identify AC and DC interfaces.
• Reference the selected converter and control equipment.
• Cross-reference isolation and protective devices.
