Deye SUN-125K-G — a high-efficiency three-phase string inverter for commercial and industrial solar power plants. It features 8 MPP trackers and a maximum efficiency of 98.8%, and supports Zero Export and VSG (Virtual Generator) functions. This inverter is ideal for facilities requiring reliable operation with minimal energy loss and flexibility in string configuration.
The device is equipped with a full set of protections and intelligent monitoring (optionally via GPRS/Wi-Fi/Bluetooth/4G/LAN), has an IP65 protection rating, and features smart air cooling. A wide MPPT input voltage range of 200–1000 V and operation in a temperature range of –25…+60 °C ensure high efficiency even under extreme conditions.
