SMA Multi-Function Relay Module
You can use the multi-function relay for various purposes:
The multi-function relay controls a display device which, depending on the type of connection, either reports an error or the undisturbed operation of the inverter.
The multi-function relay switches loads on or off, depending on the power supply status of the plant.
Control via communication/ComCtl
The multi-function relay switches the loads on and off via a communication product
The multi-function relay controls battery charging, depending on the power supply situation of the plant
The multi-function relay controls an external fan depending on the temperature of the inverter. If the temperature of the inverter is 5C higher than a specific threshold set in the inverter, the fan starts automatically. If the temperature of the inverter is 10C lower than the threshold, the fan stops automatically.
Switching status grid relay/GriSwCpy
The multi-function relay switches simultaneously with the grid relay of the inverter.
