Description
The Deye SUN-40K-G04P3 is a high-tech three-phase inverter designed for efficient operation in commercial and industrial solar power plants. It combines maximum performance, intelligent control features, and a high level of reliability.
The inverter delivers a peak efficiency of up to 98.7%, with a European efficiency of 98.1%. This allows solar energy to be converted as efficiently as possible, keeping losses to a minimum. MPPT controllers with an efficiency above 99% keep the solar panels at their optimal power point, increasing overall electricity generation.
The wide MPPT range (200–1000 V) makes it easy to adapt the system to different solar panel configurations. A startup voltage of 250 V and a nominal voltage of 600 V ensure stable startup and efficient operation even in changing lighting conditions.
The inverter supports all modern communication channels:
- Wi-Fi, Bluetooth, GPRS, 4G
- LAN (optional)
- RS485 and RS232
This provides full control over the system, access to analytics, and the ability to manage it remotely in real time.
The SUN-40K-G04P3 is equipped with a full set of protection features:
- reverse polarity protection
- overload and overvoltage
- leakage current and ground fault monitoring
- thermal protection
- DC injection limiting (< 0.5% In)
Surge protection (SPD Type II) is also provided for both DC and AC.
The inverter operates reliably in a temperature range from –25°C to +60°C (with power derating at high temperatures). The IP65 protection rating allows installation both indoors and outdoors. A noise level below 50 dB ensures comfortable operation.
The Deye SUN-40K-G04P3 is a powerful inverter for large solar systems that delivers maximum energy generation, stable operation, and full control over energy consumption. An ideal choice for those who value efficiency, reliability, and energy independence.
