Description
The Sineng SN125PT 125kW Three Phase Grid-Tie Inverter represents the pinnacle of utility-scale power conversion technology. Designed for “Safe & Reliable” operation in massive solar plants, this inverter combines “High Yield” performance with “High-Performance Management” to ensure maximum uptime and ROI.
Utility-Scale Yield & Bifacial Optimization
The SN125PT is engineered to handle the demands of the world’s largest solar arrays. With five independent MPPT trackers, it manages multiple string inputs with precision, ensuring peak performance across varied terrain. It supports an incredible 187.5kWp of DC input, facilitating high-density system designs. The unit is fully compatible with bifacial PV modules, allowing developers to capture reflected light and significantly increase total energy generation.
Industrial Reliability & Advanced Protection
Durability is non-negotiable for 125kW systems. The SN125PT features an IP66 and C5 anti-corrosion rating, making it suitable for the harshest industrial climates. It includes a built-in PID (Potential Induced Degradation) recovery function to maintain panel health and a fuseless design with smart switch-disconnectors to reduce failure points. Comprehensive safety is provided via Type II Surge Protective Devices (SPD) on both DC and AC sides and a built-in arc-fault circuit-interrupter (AFCI).
Smart Fleet Management
Managing large-scale installations is simplified with accurate string current detection and Smart I/V curve scanning, which allow for remote health diagnostics across the entire plant. Monitoring is seamless with support for RS485, WiFi, 4G, Ethernet, and an optional PLC communication port.
Why Choose the Sineng 125kW SN125PT?
- Superior Efficiency: A 98.5% max efficiency rating ensures minimal conversion loss for large-scale production.
- Intelligent Cooling: The Smart Fan Cooling system maintains stable performance even in extreme temperatures up to 60°C.
