3 Product Description
3.1 Transformer Compact Station
The Transformer Compact Station is a transformer unit that steps up low voltage to medium voltage.
The Transformer Compact Station contains low-voltage switchgear and, depending on the options
ordered, may also contain medium-voltage switchgear.
The Transformer Compact Station is connected to CP inverters in the same power class. Inverters
convert direct current to alternating current. The alternating current is then supplied to the transformer.
The alternating current is transmitted from the transformer to the switchgear and fed into the power
distribution grid.

3.1.1 Low-Voltage Switchgear
The low-voltage switchgear connects the Transformer Compact Station to the inverters. The low-
voltage switchgear can be used to disconnect the Transformer Compact Station from the inverters.
