Description
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.
The multifunction relay switches loads on or off, depending on the
power production of the PV system.
The multifunction relay switches loads on or off according to com-
mands transmitted by a communication product.
The multifunction relay controls the charging of the batteries depend-
ing on the power production of the PV system.
