Introduction
At SNEC 2025 – one of the world’s premier solar energy exhibitions – Zhejiang Liujing Rectifier Co., Ltd. took center stage as TÜV Rheinland, a globally recognized certification authority, awarded dual Bauart Mark certifications to:
🔥 Delixi Electric for its isolator switch, and
🔥 Zhejiang Liujing for its anti-reverse diodes for renewable energy, certified to IEC 60747-2 standards.
These twin achievements not only underscore China’s rising power in electrical component quality but also highlight how companies like Liujing are driving global carbon neutrality through cutting-edge technologies and uncompromising standards.
A Core Patent Product: Reinventing Safety for New Energy Systems
Liujing’s certified anti-reverse diode is purpose-built for renewable energy systems and tackles three critical industry challenges head-on:
Superior Heat Dissipation
With our patented “U-shaped composite heat sink substrate,” the diode breaks the limits of conventional cooling, ensuring long-term photovoltaic system stability and power generation efficiency.Millisecond-Level Protection
Built to IEC 60747-2 standards, the diode offers an intrinsic safety line on the DC side of power stations, preventing reverse current damage instantly.Extreme Environment Durability
A patented sealing structure and anti-corrosion alloy material help the diode endure harsh environments like offshore solar farms and desert installations. It’s the “reliable heart” of your energy system.
“The TÜV Bauart Mark represents the gold standard of German precision. Certification of Liujing’s diodes confirms our full-process production quality and capability to deliver consistent, world-class performance.”
Innovation Grounded in Reality: Practical Tech for Real-World Energy
At Liujing, we believe “innovation must meet application, and technology must respond to real-world needs.” We bring this to life through:
✅ Scenario-Based R&D
We tailor diode cluster solutions to the unique challenges of global projects, from high-salinity offshore solar in Korea to extreme heat and sandstorms in the Middle East.
✅ Smart Manufacturing as a Service
Our digital factory connects customer needs directly to the production line, with intelligent testing lines that ensure quality from the first step.
✅ Closed-Loop Global Support
Service centers in Germany, Europe, Korea, and the Middle East deliver 48-hour response times and full-lifecycle traceability – transforming after-sales into added value for our customers.
Certification Is Just the Start: Building a Global Green Energy Ecosystem
This milestone marks a key chapter in Liujing’s global journey:
🌍 Standard Breakthrough
TÜV Bauart Mark certification under IEC 60747-2 clears the way for Chinese core components to reach global markets without barriers.
🌍 Ecosystem Leadership
In partnership with TÜV Rheinland, we’re driving upgrades in safety standards across the industry to reduce global solar plant maintenance risks.
🌍 Empowering with Service
Through our “Green Component Protection Plan,” we offer technical training and spare parts support to renewable projects in developing countries – ensuring the benefits of innovation are shared worldwide.
Precision at the Core, Cooling the Planet
Every Liujing anti-reverse diode in stable operation helps reduce global carbon emissions.
“Our mission is not just to manufacture semiconductors – it’s to protect clean energy with hard-core technology. A mere 1% reduction in failure rate across global PV plants using our diodes can eliminate massive CO₂ emissions annually. That’s the impact of Precision Manufacturing, and it’s our promise to humanity.”
Liujing + Delixi: A Dual Certification That Reflects China’s Rise from Compliance to Global Leadership
Driven by the shared mission to cool the planet, Liujing is powering the renewable energy era with patented technology, practical innovation, and world-class service – embodying the strength of the ‘China Chip’ on the global stage.
Zhejiang Liujing Rectifier Co., Ltd.
