Description

The Deye SUN-120K-G03P3 grid 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 generation stability and yield optimisation are critically important.

The inverter provides a rated power of 120 kW and achieves an efficiency of up to 98.8%, which makes it possible to obtain the maximum energy from the solar panels with minimal losses. Thanks to 8 independent MPPT trackers, the device works efficiently with several panel arrays, even if they are positioned at different angles or orientations. This is especially relevant for complex rooftop and ground-mounted solar power plants.

A wide input voltage range of up to 1000 V and support for a high PV Voc of up to 1100 V ensure compatibility with modern high-voltage modules and allow the system to be designed flexibly. The rated DC voltage is around 600 V, which is optimal for most industrial configurations.

The three-phase 3L+N+PE output with a high power factor and a low level of harmonic distortion (THDi <3%) guarantees stable operation of the power grid and of the connected equipment. The inverter supports operation at 50/60 Hz, as well as zero-export and VSG (virtual synchronous generator) functions for greater energy system stability.

Particular attention has been paid to safety: the model is equipped with comprehensive protection, including a type II SPD, protection against reverse polarity, overload, overvoltage and overheating, as well as Anti-PID and anti-islanding functions. The built-in DC switch and the current leakage monitoring system provide an additional level of reliability.

The inverter has an IP65 protection rating, which allows it to be operated outdoors in harsh climatic conditions. The intelligent cooling system maintains stable operation even at high temperatures, providing predictable derating in the +45…+60 °C range.

RS-485 and RS-232 interfaces are provided for convenient control, along with optional Wi-Fi, LAN, 4G and Bluetooth modules. This makes it possible to integrate the inverter into remote monitoring systems, track parameters in real time and respond promptly to any changes in system operation.

The design of the device is adapted for quick installation: MC4-compatible connectors are supported, and convenient wiring and simple start-up via the local interface or the mobile app are provided. The sturdy housing with an anti-corrosion coating guarantees durability even in industrial operating conditions.

Deye SUN-120K-G03P3 is an efficient and scalable foundation for modern solar power plants, providing stable generation, configuration flexibility and a high level of energy independence for business, industry and large infrastructure facilities.
