Description of the device

3.1

Mode of operation

The device converts the DC voltage generated by the PV-modules into AC voltage and feeds this into the power grid. The
starting procedure begins when there is sufficient sunlight and a specific minimum voltage is present in the device. The
feed-in process begins once the PV generator has passed the insulation test and the grid parameters are within the re-
quirements imposed by the grid operator for a specific monitoring time. If, as it gets dark, the voltage drops below the
minimum voltage value, feed-in mode ends and the device switches off.

3.2.1 Mechanische Komponenten
The DC disconnector is located on the left side of the unit. The DC isolating switch is used to disconnect the inverter from
the PV generator when servicing is required.
Disconnecting the device from the PV generator
F Switch the DC isolator switches from 1 (ON) to 0 (OFF).
Connecting the device to the PV generator
F Switch the DC isolator switches from 0 (OFF) to 1 (ON).
3.2.2 Electrical functions
A potential-free relay contact is integrated into the device. Use this contact for one of the following functions:
Potential-free 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.
Priwatt
The energy that is provided by the PV system can be put to use directly by the appliances that are connected in your
home.
The potential-free contact can switch larger appliances (e.g. air conditioning units) on and off with the Priwatt function
activated. This requires an external power supply and an external load relay.
