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) |
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. |
