Key Definition / information on the connection
PV generator The PV generator converts the radiant energy of sunlight
into electrical energy.
Inverter with circuit-breaker The PV generator is connected to the device's DC connec-
tion.
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 meters.
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 en-
ergy drawn.
Transformer
NOTE:The earthing is carried out in the outgoing
neutral point. (Dy5)
All three phases need to be set up on the medium-voltage
transformer or medium-voltage/high-voltage transformer.
In this case, the total impedance of the transformer stations
must be below 25%.
Grid connection point The clean PV-current is made available at the grid connec-
tion point.
DC isolator switch Use the DC isolator switch to disconnect the device from
the PV generator.
