PV AFD

Symbols

Photovoltaic arc-fault detection

Solar arc-fault detection analyses monitored circuit behaviour for signs of specified electrical arcing.

Drawing use: Schematic
Application: Metering & protection
Reference family: Manufacturer

A distinction that matters

Detection, decision logic and power interruption must be distinguished in the design.

PV INV

Symbols

Photovoltaic inverter

A photovoltaic inverter converts a documented PV DC input into an AC output and provides the selected PV control functions. Its schematic keeps DC strings, AC connection and control/protection interfaces distinct.

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

A distinction that matters

A PV inverter is different from a battery converter even when both connect to the same AC bus.
