Description
The Deye SUN-120K-G03P3 grid-tie inverter is a professional solution for large commercial and industrial solar power plants that combines high power, intelligent control, and maximum operating efficiency. The model is designed for facilities with high energy consumption, where stable generation and optimized output are critical.
The inverter delivers a rated power of 120 kW and reaches an efficiency of up to 98.8%, allowing you to get the maximum energy from solar panels with minimal losses. Thanks to 8 independent MPPT trackers, the device works efficiently with multiple panel arrays, even if they are installed at different angles or orientations. This is especially relevant for complex rooftop and ground-mounted solar plants.
A wide input voltage range of up to 1000 V and support for a PV Voc of up to 1100 V ensure compatibility with modern high-voltage modules and allow flexible system design. The rated DC voltage is about 600 V, which is optimal for most industrial configurations.
The three-phase 3L+N+PE output with a high power factor and low harmonic distortion (THDi <3%) guarantees stable operation of the grid and connected equipment. The inverter supports operation at 50/60 Hz, as well as zero-export and VSG (virtual synchronous generator) functions to improve power system stability.
Special attention is paid to safety: the model is equipped with comprehensive protection, including Type II SPD, reverse polarity, overload, overvoltage, and overheating protection, as well as Anti-PID and anti-islanding functions. The built-in DC switch and leakage current monitoring system provide an additional level of reliability.
The inverter has an IP65 protection rating, which allows it to be used outdoors in challenging climate conditions. The intelligent cooling system maintains stable operation even at high temperatures, providing predictable derating in the +45…+60 °C range.
For convenient control, RS-485 and RS-232 interfaces are provided, as well as optional Wi-Fi, LAN, 4G, and Bluetooth modules. This allows you to integrate the inverter into remote monitoring systems, track parameters in real time, and respond quickly to any changes in system operation.
The design of the device is adapted for fast installation: MC4-compatible connectors are supported, and convenient connection and simple commissioning are available through the local interface or a mobile app. The durable housing with an anti-corrosion coating ensures longevity even in industrial operating conditions.
The Deye SUN-120K-G03P3 is an efficient and scalable foundation for modern solar power plants, delivering stable generation, configuration flexibility, and a high level of energy independence for businesses, industry, and large infrastructure facilities.
