Core Advantages of CHBEST PV Grid-tied Inverter with Integrated Transformer
CHBEST Power's PV grid-tied inverter with integrated transformer is specifically engineered for 1MW solar farms, addressing the core needs of efficiency improvement, space saving, and grid stability. By integrating the inverter, transformer, and distribution unit into a single system, the product eliminates redundant connections and components, delivering superior performance and operational reliability compared to traditional split-type solutions.
1. CE Certification and EU Standard Compliance
CE certification is a mandatory requirement for PV inverters entering the EU market, ensuring compliance with strict safety, electromagnetic compatibility, and environmental standards. CHBEST's integrated inverter has obtained CE certification, fully adhering to the Low Voltage Directive (LVD 2014/35/EU), Electromagnetic Compatibility (EMC) Directive (2014/30/EU), and relevant IEC standards including IEC 62109-1/2 for photovoltaic inverters. The certification process was conducted by TÜV Rheinland, a globally recognized third-party testing body, covering rigorous tests on conversion efficiency, insulation strength, overvoltage protection, and electromagnetic interference.
To maintain compliance, CHBEST Power has established a complete technical documentation system, including design specifications, component certifications, test reports, and EU Declaration of Conformity (DoC). Every batch of inverters undergoes pre-shipment inspection to ensure consistent quality, eliminating market access risks for EU clients. The product also complies with the EU's new battery and carbon footprint regulations, aligning with the region's green energy policies.
2. High Integration and Space-Efficient Design
For 1MW solar farms—especially agrivoltaic projects popular in EU countries like Greece—the efficient use of space is critical. CHBEST's integrated inverter combines the inverter, dry-type transformer, and low-voltage distribution cabinet into a single compact unit, reducing占地面积 by up to 65% compared to traditional split systems . The modular design features a lightweight structure, with weight reduced by 58% relative to conventional solutions, significantly lowering transportation and on-site installation costs.
The integrated design eliminates the need for separate cable connections between the inverter and transformer, adopting copper bar connections instead to reduce energy loss by 3-5% and avoid cable aging risks . The unit is pre-assembled and fully tested at the factory, minimizing on-site construction time by 40% and reducing labor costs for 1MW farm projects. This design is particularly suitable for agrivoltaic scenarios, where installation space is limited by agricultural production requirements .
3. Superior Conversion Efficiency and Energy Yield
Maximizing energy yield is a core priority for 1MW solar farm operators. CHBEST's integrated inverter achieves a maximum conversion efficiency of 99.2% and a European Efficiency (ηEU) of 98.9%, ranking among the industry's top levels. The product adopts a high-performance MPPT (Maximum Power Point Tracking) algorithm with a tracking accuracy of over 99.5%, effectively capturing solar energy even under partial shading conditions common in farm environments.
The integrated dry-type transformer features low no-load loss and low noise operation (≤65dB), ensuring efficient energy transfer while meeting the EU's environmental noise standards for rural areas. The transformer is designed to adapt to the variable output of solar panels, avoiding overload derating and maximizing power generation . For a 1MW solar farm, these efficiency advantages can increase annual energy yield by 2-3%, delivering significant economic benefits to operators.
4. Strong Grid Adaptability and Stability
EU power grids, particularly in rural areas with 1MW solar farms, often face weak grid conditions and voltage fluctuations. CHBEST's integrated inverter is equipped with advanced grid-friendly control technology, supporting low-voltage ride-through (LVRT) capability and reactive power compensation. It can operate stably in weak grid environments with a Short-Circuit Ratio (SCR) as low as 1.2, quickly adjusting active and reactive power to respond to grid voltage and frequency fluctuations .
The product integrates IEC 61850 communication functionality, enabling seamless connection to the farm's central control system and the EU's smart grid network. Real-time data on conversion efficiency, output power, and equipment status is transmitted via Ethernet or wireless protocols, supporting remote monitoring, fault early warning, and predictive maintenance. For farms equipped with energy storage systems—required for at least one hour of storage in Greek agrivoltaic projects —the inverter offers flexible compatibility with various battery types, ensuring stable energy supply to the grid.
5. Robust Environmental Adaptability
1MW solar farms in the EU operate in diverse climatic conditions, from humid coastal areas to high-altitude regions and cold inland areas. CHBEST's integrated inverter features an IP65 protection rating—industry-leading for outdoor use—effectively preventing dust, water, and corrosive gas intrusion . The unit is designed to operate in extreme temperatures ranging from -40℃ to +70℃, with a built-in intelligent cooling system that adjusts fan speed based on temperature, ensuring stable performance in harsh environments.
