Multifunction relay (MFR)

The inverter is equipped with 2 multifunction relays as standard.
A multifunction relay is an interface that can be configured for the operating mode used by a particular system.
The multifunction relays can be connected to the unit to be controlled externally via the 3-pole plug-in contact and a signal line with mating connectors. Both are included in the inverter's scope of delivery.
Multifunction relays can only be used if the inverter is configured as the SMA System Manager.
