Deye SUN-25K-G05P3 String 25KW Grid-Tie Inverter

The Deye SUN-25K-G05P3 series comprises modern three-phase grid-tied inverters created for the most efficient conversion of solar energy. They combine high performance, extensive functionality and reliability, which makes them an ideal solution for commercial and industrial solar power plants.

The inverter delivers a maximum efficiency of up to 98.6%, while the European efficiency figure reaches 98%. This means minimal energy losses and the maximum return from the solar panels. The MPPT controllers demonstrate an efficiency of more than 99%, automatically determining the optimal operating point to achieve the highest generation.

The wide MPPT range (200–1000 V) and the well-designed input system ensure compatibility with different types of photovoltaic modules. A start-up voltage from 250 V and a rated voltage of 600 V allow the system to start efficiently even in changing light conditions.

Power and stability

• Rated power: 25 kW
• Maximum power: up to 27.5 kVA
• Grid support: 220/380 V and 230/400 V

The three-phase connection ensures stable operation and even load distribution, which is especially important for businesses and large facilities.

The inverter supports modern communication methods:

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

This makes it possible to monitor system operation in real time, analyse performance and respond quickly to changes.

The SUN-25K-G05P3 is equipped with a multi-level safety system:

• overvoltage and overload protection
• DC reverse polarity protection
• leakage current and earth fault monitoring
• thermal protection
• DC injection limiting

Surge protection (SPD type II) is additionally provided on both the DC and the AC side.

The inverter operates stably in a temperature range from –25°C to +60°C (with automatic power derating at high temperatures). The IP65 protection class allows the device to be installed both indoors and outdoors, while a noise level below 50 dB ensures comfortable operation. Compact dimensions (362×527×220 mm) and a weight of about 20 kg make it possible to install the inverter quickly without complex engineering solutions. Servicing is also extremely simple.

Deye SUN-25K-G05P3 is a powerful, efficient and technologically advanced inverter that lets you get the most out of a solar power plant. It is ideal for those who seek stability, high performance and energy independence.
