2.1 Intended Usage
This series of Power Conversion System researched and developed by Sungrow Power
Supply Co., Ltd., is a PCS for energy storage system without transformer. It provides an
interface for the grid and battery for storage system charging and discharging. Through
step up by the external transformer, the PCS AC side can connect to the grid or load.
With TYPE 3R protection rate, the PCS can be installed outdoors.
Through the external medium-voltage transformer, the AC output voltage of PCS will be
raised to conform to parameters of local utility grid. Then the PCS can be connected to
the grid. For specific technical requirements of transformer, please refer to the "-
Connection Requirements of Medium-Voltage Transformer".
The charging and discharging system with Power Conversion System is shown below:
