Deye 500kW Static Transfer Switch (STS) Module | Seamless Grid & Generator Switching for C&I Energy Systems

The Deye 500kW Static Transfer Switch (STS) Module is a high-capacity switching solution engineered for commercial and industrial energy storage systems. Designed to work in tandem with Deye’s 125kW Power Conversion System (PCS), the STS module enables fast, reliable switching between multiple power sources, including grid, generator, and off-grid modes.

Key Features:

• High Switching Capacity: Supports up to 500kW of switching power, ideal for large-scale energy systems.
• Ultra-Fast Transfer Time: Seamless switching between grid, generator, and off-grid modes in less than 10 milliseconds.
• Multi-Path Support: Independent high-power paths for diesel generator, grid, and load connections, each supporting up to 500kW.
• Scalable Architecture: One STS module can connect to up to five 125kW PCS units; multiple STS modules can be paralleled to support systems up to 2.5MW.
• Integrated Protection: Built-in surge protection, overcurrent, short-circuit, and thermal safeguards ensure safe operation.
