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.
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.
The reference counter is to be specified and installed by the
power supply company. This measures the amount of en-
ergy drawn.
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%.
The clean PV-current is made available at the grid connec-
tion point.
Use the DC isolator switch to disconnect the device from
the PV generator.
