function relay (Mlt.Op-
Mode)
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 (SelfC-
smp)
The multifunction relay switches loads on or off, depending on the
power production of the PV system.
Control via communica-
tion (ComCtl)
The multifunction relay switches loads on or off according to com-
mands transmitted by a communication product.
Battery bank (BatCha)
The multifunction relay controls the charging of the batteries depend-
ing on the power production of the PV system.
