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 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.

Definition / information on the connection
The PV generator converts the radiant energy of sunlight
into electrical energy.
The PV generator is connected to the device's DC connec-
tion.
Use the DC isolator switch to disconnect the device from
the PV generator.
The circuit breaker is an overcurrent protection device.
The feed-in meter is to be specified and installed by the
power supply company. Some power supply companies also
allow the installation of your own calibrated meters.
The selective main switch is to be specified by the power
supply company.
