The Deye SUN-STS500L is a high-performance 500kW Static Transfer Switch (STS) specifically engineered for large-scale commercial and industrial (C&I) energy storage systems. It serves as the intelligent management hub, enabling ultra-fast, seamless transitions between the electrical grid, diesel generators, and battery storage to ensure power continuity for critical loads.
Key Performance Specifications
- Rated Power: 500 kW active power capacity.
- Transfer Time: Ultra-fast switching typically under 10ms, preventing equipment resets during source changes.
- Rated Current: Supports 725A to 758A depending on the specific voltage configuration.
- Voltage Support: Three-phase compatibility for 380V/400V systems (50/60Hz).
- Ingress Protection: Rated IP20 (designed for indoor or cabinet installation) or IP54/IP65 in specific ruggedised enclosures.
System Integration & Scalability
- Modular Design: A single STS unit can manage up to five 100kW or 125kW Deye PCS (Power Conversion System) modules.
- Independent Paths: Features three dedicated, full-capacity paths for the Grid, Load, and Diesel Generator, each supporting up to 500kW.
- Parallel Capability: Multiple STS units can be operated in parallel to support larger systems up to 2.5MW.
- Smart Control: Includes RS485 and CAN communication interfaces for integration with the Deye Cloud and local Energy Management Systems (EMS).
Physical Data
- Weight: Approximately 108 kg for the module itself.
- Dimensions: Approximately 543 × 575 × 671 mm for the core module.
- Cooling: Uses intelligent air cooling or natural cooling depending on the specific model variant.
