4 Product Description
4.1 System Overview
The Transformer Compact Station is a transformer unit that converts low voltage into high voltage. The
Transformer Compact Station is equipped with a low-voltage power switch and a high-voltage transformer.
Figure 2: Principle of a grid-tie PV power plant with Transformer Compact Station
Only Sunny Central inverters of the CP-JP production series are connected to the Transformer Compact Station.
The inverter converts the direct current into alternating current. The alternating current is then supplied to the high-voltage
transformer. The alternating current is transmitted from the high-voltage transformer to the switchgear and fed into the
utility grid.
