Huawei SUN2000-40K-MC0 40kW 3-Phase Inverter

The Huawei SUN2000-40K-MC0 is a three-phase transformerless inverter designed for commercial and industrial PV installations. With a rated AC output power of 40 kW and maximum efficiency of 98.6%, it delivers high performance across a wide range of operating conditions. The inverter features 4 independent MPPT (Maximum Power Point Tracking) units with 8 inputs, enabling optimized energy harvest even under partial shading or variable irradiance.

Safety and reliability are integrated throughout the design. The unit includes Type I+II DC surge protection, Type II AC surge protection, integrated arc fault detection (AFCI), DC reverse-polarity protection, and comprehensive monitoring of insulation resistance and residual currents. PID (Potential-Induced Degradation) recovery is built-in, supporting P-type and N-type module technologies.

Communication and monitoring are streamlined via integrated WLAN and the FusionSolar app for real-time data access, with optional 4G connectivity and RS485 connectivity. The IP66-rated aluminum housing and natural convection cooling ensure durability in outdoor environments across operating temperatures from −25 °C to +60 °C.
