Operating Modes of the Multifunction Relay


Operating mode of multifunction relay (Mlt.OpMode)

Description

Fault indication (FltInd)

The multifunction relay controls a display device (e.g. a warning light) which, depending on the type of connection, signals either an error or the undisturbed operation of the inverter.

Self-consumption (SelfCsmp)

The multifunction relay switches loads on or off, depending on the power production of the PV system.

Control via communication (ComCtl)

The multifunction relay switches loads on or off according to commands transmitted by a communication product.

Battery bank (BatCha)1)

The multifunction relay controls the charging of the batteries depending on the power production of the PV system.

Fan control (FanCtl)

The multifunction relay controls an external fan, depending on the temperature of the inverter.

Switching status grid relay (GriSwCpy)

The local grid operator may require that a signal is transmitted as soon as the inverter connects to the utility grid. The multifunction relay can be used to trigger this signal.
