Deye SUN-35K-G04P3 String 35KW Grid-Tie Inverter

Deye SUN-35K-G04P3 is a high-performance three-phase inverter developed for stable and maximally efficient operation as part of commercial and industrial solar power plants. It combines advanced technologies, high reliability and flexible integration into a variety of power systems.

The inverter delivers a peak efficiency of up to 98.6%, while its European efficiency figure reaches 98%. This guarantees minimal energy losses and maximum return from every solar module. MPPT controllers with an efficiency of over 99% automatically optimise the operation of the panels, ensuring stable generation even under changing light conditions.

A wide MPPT range (200–850 V) makes it possible to work efficiently with different solar panel configurations. A start-up voltage from 250 V and a rated 850 V ensure fast start-up and stable system operation.

High power output

• Rated power: 35 kW
• Maximum power: up to 38.5 kVA
• Grid support: 220/380 V and 230/400 V

The three-phase connection (3L/N/PE) guarantees even load distribution and a stable power supply.

The inverter supports modern communication methods:

• Wi-Fi, Bluetooth, GPRS, 4G
• optional LAN
• RS485 and RS232 interfaces

This enables remote supervision, performance analysis and prompt management of the system in real time.

The SUN-35K-G04P3 is equipped with a multi-level safety system:

• protection against incorrect DC polarity
• protection against AC overloads and overvoltages
• leakage current and earth fault monitoring
• thermal protection
• DC injection limiting (< 0.5 % Iₙ)

Surge protection (SPD type II) on the DC and AC sides is additionally implemented.

The inverter operates in a temperature range from –25°C to +60°C, with automatic power derating in case of overheating. The IP65 protection rating allows the device to be installed both indoors and outdoors. A noise level below 50 dB ensures comfortable operation.

Deye SUN-35K-G04P3 is a powerful, efficient and technologically advanced inverter for modern solar power plants. It ensures stable generation, a high level of safety and full control over the power system, helping to achieve maximum energy efficiency.
