3 Description
3.1 Mode of Operation
The inverter converts the DC voltage generated by the PV modules into AC voltage and feeds it into the grid. The
feed-in process begins when there is suffi
cient sunlight and a specifi c minimum voltage is present in the inverter.
If, as it gets dark, the voltage drops below the minimum voltage value, the feed-in mode ends and the inverter
switches off .

3.2.1 Mechanical components
DC isolator switch
The DC isolator switch is located on the underside of the inverter. The DC isolator switch is used to disconnect the
inverter from the PV generator in order to carry out service.
Disconnecting the inverter from the PV generator
 Switch the DC isolator switches from 1 (ON) to 0 (OFF).
Connecting the inverter to the PV generator
 Switch the DC isolator switches from 0 (OFF) to 1 (ON).
3.2.2 Electrical functions
Fault signal relay/priwatt
A potential-free relay contact is integrated in the inverter. Use this contact for one of the following functions:
Fault signal relay
The potential-free relay contact closes as soon as there is a fault during operation. You use this function, for example,
to signal a fault visually or acoustically.
