Deye SUN-40K-G04P3 String 40KW Grid-Tie Inverter

Deye SUN-40K-G04P3 is a high-tech three-phase inverter created for efficient operation in commercial and industrial solar power plants. It combines maximum performance, intelligent control functions and a high level of reliability.

The inverter delivers a peak efficiency of up to 98.7%, while the European efficiency reaches 98.1%. This makes it possible to convert solar energy as efficiently as possible, keeping losses to a minimum. MPPT controllers with an efficiency of over 99% keep the solar panels at the optimal power point, which increases the total electricity yield.

A wide MPPT range (200–1000 V) makes it easy to adapt the system to different solar panel configurations. A start-up voltage of 250 V and a nominal voltage of 600 V ensure stable start-up and efficient operation even under changing light 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 possibility of remote management in real time.

The SUN-40K-G04P3 is equipped with a full set of protective functions:

• reverse polarity protection
• overload and overvoltage protection
• leakage current and ground fault monitoring
• thermal protection
• DC injection limitation (< 0.5 % In)

Surge protection (SPD type II) for DC and AC is also provided.

The inverter works stably in a temperature range from –25°C to +60°C (with power derating at high temperatures). The IP65 protection class allows installation both indoors and outdoors. A noise level of less than 50 dB ensures comfortable operation.

Deye SUN-40K-G04P3 is a powerful inverter for large solar systems that ensures maximum energy generation, stable operation and full control over energy consumption. The ideal choice for those who value efficiency, reliability and energy independence.
