DEYE Three Phase Inverter

1. Tailored Solar Solutions

We reject the "one-size-fits-all" approach-whether you're a homeowner looking to build a "zero-carbon residence," a commercial park needing to upgrade your energy structure, or a remote area seeking stable off-grid power supply, we offer ODM/OEM customized services: from system capacity planning, PV module selection, to energy storage system matching and intelligent monitoring solution design, our professional team coordinates the entire process to ensure every solar system precisely fits your site conditions, electricity demand, and investment expectations.

2. Premium-Grade Solar Products

Power generation efficiency and long-term stability are the "lifelines" of a PV system. We strictly select top-tier supply chain resources: PV modules adopt anti-PID (Potential Induced Degradation) technology + high-transmittance tempered glass, and inverters are equipped with intelligent power optimization algorithms. Moreover, we have established a full-process quality control system-from raw material inspection to finished product aging tests-every step is strictly checked to ensure the products maintain high efficiency in complex environments such as high temperature, high humidity, and strong wind and sand, with a service life far exceeding industry standards. This allows your clean energy investment to "pay off once and benefit for the long term."

3. Advanced Equipment & R&D

The technological iteration of the photovoltaic industry determines the upper limit of energy efficiency. We continuously invest in million-level advanced production equipment​ (such as fully automatic string welders, IV power testers) to ensure the electrical performance consistency of modules. At the same time, we collaborate with research institutions to tackle cutting-edge technologies like high-efficiency heterojunction (HJT) cells​ and optical-storage integration coupling technology. This ensures your solar system is not just a "current power solution" but also a "future value-added asset"-it can adapt to grid peak-valley regulation trends and continuously increase power generation revenue as technology upgrades.

4. One-Stop Full-Cycle Service

From "energy transformation" to "peace of mind in power usage," we handle the entire process for you:

Pre-project: Free on-site energy audit to accurately calculate the power generation potential of your roof/site;

Mid-project: Personalized solution design (integrating architectural aesthetics + power generation efficiency) and standardized construction by a professional team;

Post-project: 24/7 intelligent operation and maintenance platform for real-time monitoring, fault response within 2 hours, and annual inspection + module cleaning services.

The Deye SUN-23/25/30K-G04-LV is a series of3-phase, low-voltage (LV), on-grid string inverters (23kW–30kW) designed for large residential and commercial solar installations. Featuring up to 4 MPPTs, 98.7% efficiency, and 127/220V or 133/230V grid compatibility, these inverters maximize yield and reduce energy costs with zero-export capabilities.

1. Next-Gen Power Conversion Architecture

At the heart of the SUN-25K-G04-LV lies a sophisticated conversion topology that prioritizes efficiency without compromising on stability. Achieving a maximum efficiency of 98.7%, this inverter ensures that the jump from DC to AC power suffers minimal thermal loss. This isn't just a number; it translates directly to more kilowatt-hours fed back into the grid or consumed on-site over the system's 25-year lifecycle.

2. Adaptive Grid Management

One of the standout capabilities of this series is its Virtual Synchronous Generator (VSG) function.

Many traditional inverters shut down in the event of a disturbance within the electrical grid. The Deye G04-LV actively assists the grid through its imitation of a conventional generator's inertia, which helps stabilize the voltage and frequency during disturbed conditions; i.e., the G04-LV has no unplanned shutdowns for your customers and is compliant with stringent conditions imposed by modern electric service regulations such as EN 50549 and RD 140.

3. The "Anti-PID" Factor for Long-Term Yield

Potential Induced Degradation (PID) is the silent killer of solar panel performance, gradually reducing power output. While often overlooked in initial proposals, the optional Anti-PID function safeguards the client's investment by preventing this power loss. Offering this feature positions you as a consultant who cares about long-term asset health, not just the initial installation cost.

The physical integrity of an inverter is critical for outdoor commercial installations. The Deye G04-LV line is housed in a solid metal case (built of aluminum or a combination of both). Unlike plastic enclosures, which will deteriorate from extended exposure to UV radiation and heat, a metal enclosure acts as a better heat sink and provides a higher degree of mechanical strength against nature than a plastic enclosure.

IP65-rated (completely protected against dust and any low-pressure water jets), the unit can be installed anywhere - in dusty factory floors or exposed to the elements - without requiring protection from an outside source.

We understand that a hardware failure on a commercial site can lead to significant revenue loss. Therefore, every Deye SUN-23/25/30K-G04-LV comes with a standard 5-year warranty, with options for extension available.

The Digital Ecosystem

Monitoring: The Deye Inverter can be monitored in a number of ways, including but not limited to: Wi-Fi, 4G, GPRS, Bluetooth, and LAN (via optional dongles).

Platform: The Deye Monitoring Portal allows both your team and the end user to access live performance metrics, as well as fault alerts and historical data remotely using their smartphone or computer.

Customization for OEM Partners

For volume buyers, we offer OEM services including custom logo imprinting, customized packaging, and graphic customization to align with your brand identity.

The Commercial Rooftop: Example applications include offgrid solar on roof tops such as a 30 kw system installed on a retail store utilizing 4 mppt trackers to accommodate panels facing south, east and west for maximum self-consumption.

The Agricultural Shed: Utilizing the IP65 rating to withstand the humid and dusty environment of a livestock barn while powering ventilation and milking equipment.

The Industrial Micro-grid: Paired with the VSG function to support a factory"s sensitive CNC machinery against grid fluctuations.

Q: Does it work with high-power bifacial modules?
A: Yes. Each MPPT supports up to 32A current and 800V DC, compatible with 600W+ modules.

Q: How are inverters packed for sea freight?
A: Each unit is foam-protected in a carton, then strapped to pallets and wrapped for moisture resistance.

Q: What's the warranty and replacement process?
A: Standard 5-year warranty, with extensions available. Hardware failures qualify for our "Replacement First" policy to minimize downtime.

Q: Is it certified for European grids?
A: Yes – complies with VDE, CEI 0-21, EN 50549, G99, etc. Firmware is pre-set for your destination country.

Q: Can we integrate it with our SCADA?
A: Yes. It supports Modbus-RTU over RS485; register map available. Optional Wi-Fi/4G for cloud monitoring.
