The Deye SUN-125K-PCSL01HP3 is a high-performance 125kW Power Conversion System (PCS) designed for commercial and industrial (C&I) energy storage applications. It serves as a bidirectional interface between high-voltage battery systems and the AC grid, enabling efficient charging and discharging for peak shaving, load shifting, and backup power.
Key Specifications
- Rated AC Output Power: 125 kW.
- Efficiency: Maximum efficiency of 98.5%.
- Battery Voltage Range: Operates within 630–1000 V DC.
- Max Charging/Discharging Current: Up to 220 A.
- Grid Connection: Three-phase 3L+N+PE (220/380V or 230/400V).
- Ingress Protection: IP65 rated for outdoor or indoor deployment.

Core Features
- Bidirectional Operation: Functions as both an inverter and a charger, facilitating energy flow between the grid and batteries.
- Integrated EMS: Built-in Energy Management System (EMS) supports zero-export control, time-of-use scheduling, and demand management.
- Fast Source Switching: When used with a Deye STS (Static Transfer Switch) module, it can switch between on-grid and off-grid modes in less than 10 ms.
- Surge Capability: Supports 110% overload and instantaneous peak power up to 170% (some sources indicate up to 200% for 15 seconds).
-
Communication: Equipped with CAN, RS485, Wi-Fi, and Ethernet interfaces for monitoring and SCADA integration.
Common Applications
- Battery Energy Storage Systems (BESS): Critical for utility-scale battery integration.
- Microgrids: Ideal for stabilizing energy flow in independent or semi-independent grids.
- Industrial Peak Shaving: Reduces electricity costs by discharging batteries during peak demand periods.
-
EV Charging Integration: Manages high-power loads for large-scale electric vehicle charging stations.
