Device description

3.1

Function

The device converts the DC voltage generated by the PV modules into AC voltage and feeds it into the grid. The
starting procedure begins when there is sufficient sunlight and a specific minimum voltage is present in the de-
vice. The feed-in process begins once the PV generator has passed the insulation test and the grid parameters
are within the requirements 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 Mechanical components
DC isolator switch (not present in S version)
The DC isolator switch is located on the housing door. of the device. The DC isolator switch is used to discon-
nect the device from the PV generator in order to carry out service.
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:
Fault signal relay
The potential-free relay contact closes as soon as there is a fault during operation. You use this function, for ex-
ample, to signal a fault visually or acoustically.
