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 it into the power grid. The starting

procedure begins when there is sufficient sunlight and a minimum voltage is present in the device. The feed-in process begins

once the PV generator has successfully 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.

Key

Definition / information on the connection

PV generator

The PV generator converts the radiant energy of sunlight

into electrical energy.

Inverter

The PV generator is connected to the device’s DC

connection.

Line protection

The circuit breaker is an overcurrent protection device.

Feed-in meter

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 counters.

Selective main switch

The selective main switch is to be specified by the power

supply company.

Reference counter

The reference counter is to be specified and installed by

the power supply company. This measures the amount of

energy drawn.

Integrated DC isolator switch

Use the integrated DC isolator switch to disconnect the

device from the PV generator.
