125KW 3-Phase Industrial Inverter

The Bluesun BSM125K-B 125kW Grid-Tied String Inverter is designed for commercial and industrial solar power systems, offering high efficiency, flexible design, and stable long-term operation. It operates on a 3-phase 230/400Vac grid connection and can connect directly to the utility grid without an external transformer, reducing installation complexity and cost.

Built for modern high-power PV modules, it supports 182mm and 210mm panels and is optimized for systems using 500W+ modules. With a maximum efficiency of up to 98.7%, it ensures strong energy conversion and minimal losses across a wide range of operating conditions.

The inverter features 8 MPPTs with up to 40A input current per MPPT, allowing precise string-level tracking and improved energy yield in large or complex installations. Its wide MPPT voltage range (200V–1000V) and high DC input capability (up to 1100V) provide strong design flexibility, while a DC/AC ratio of up to 1.5 supports PV oversizing for increased output.

Engineered for durability, it includes an IP66-rated enclosure, Type II DC/AC surge protection, and integrated lightning protection. Smart fan cooling ensures stable performance in demanding environments, operating from -30°C to 60°C and maintaining full output up to 45°C. The transformer-less design improves efficiency and reduces overall system weight.

For monitoring and control, the inverter supports RS485, PLC communication, and optional WiFi or 4G connectivity, with Bluetooth app-based setup for quick commissioning and remote system management.
