24/7 without days off
Deye SUN-125K-PCS01HP3 is an advanced three-phase high-voltage PCS (Power Conversion System) inverter, specifically designed for the commercial and industrial (C&I) sectors. It is the "brain" of high-capacity Energy Storage Systems (ESS). This model is ideal for factories, shopping malls, warehouse complexes, agricultural enterprises, and other critical infrastructure facilities that require energy independence, electricity cost optimization, and blackout protection.
Key Business Benefits and Functionality
Cost Optimization (Peak Shaving): The inverter supports intelligent charge/discharge scheduling. It allows storing energy at night (at a lower tariff) and using it during peak load hours (when grid energy is most expensive), significantly reducing electricity bills.
Creating Powerful Microgrids (Microgrid): The ability to connect up to 10 such inverters in parallel allows creating a unified system with a capacity of up to 1.25 MW.
Integration with Diesel Generators: Deye SUN-125K has built-in functionality for joint operation with fuel generators. The inverter can automatically start the generator when batteries are discharged or when solar generation critically drops, optimizing fuel consumption.
100% Unbalanced Load: The inverter can output different power levels to each of the three phases, which is critically important for industrial facilities with specific or uneven equipment loads (e.g., powerful machines on one phase and lighting on another).
Extended Technical Specifications
Nominal Output Power: 125 kW
Maximum Output Power (Peak): 137.5 kW
Battery Parameters: Operates exclusively with high-voltage batteries (range 630 V – 1000 V), which reduces currents and minimizes energy losses from cable heating. The maximum charge/discharge current is 200 A.
Power Quality: Total Harmonic Distortion (THDi) < 3%, ensuring a "clean" sine wave safe for sensitive electronics, server rooms, and medical equipment.
Switching Time: Seamless switching to backup power (UPS level) — less than 20 milliseconds. The enterprise will not even notice the grid outage.
Reliability and Safety
The inverter is designed for harsh operating conditions and features a multi-level protection system:
Built-in Direct Current (DC) and Alternating Current (AC) overvoltage protection (Type II).
Leakage current protection and insulation monitoring.
Intelligent forced air cooling with fan redundancy, preventing overheating during prolonged maximum loads.
Enclosure Protection Rating IP65 (full protection against dust and water jets), allowing outdoor installation.
Interface and Control
To ensure easy setup, monitoring, and integration with other enterprise systems (BMS/EMS), the device features a well-thought-out interface. Local control is carried out via a convenient touch display on the enclosure. For remote monitoring and dispatching, an extended data transmission interface is available, which includes RS485, CAN ports, and a Wi-Fi module. This allows real-time tracking of generation, battery status, and consumption via a convenient app or web portal.
