Powerhouse Collaboration Shines at SNEC 2025!

TÜV Rheinland's dual certifications highlight China's commitment to quality manufacturing, while LJ-MD's robust anti-reverse diodes safeguard the planet's green energy.

At the global photovoltaic event SNEC 2025, a highlight moment unfolded: the internationally authoritative certification body TÜV Rheinland awarded two Bauart Mark certifications:

Delixi Electrical Isolation Switch Passes TÜV Rheinland Certification

LJ-MD New Energy Anti-Reverse Diode Passes IEC 60747-2 Standard Certification

This dual recognition not only signifies that China's power component safety standards are fully aligned with international standards but also highlights the commitment of Chinese companies like Liu Jing to advancing global carbon neutrality through “hard technology + strict standards.”

Hardcore patented products: Building the “safety foundation” of new energy with invention patents

The core product certified this time—the new energy-specific anti-reverse diode—addresses three major industry pain points:

- Ultra-efficient heat dissipation: The patented “U-shaped groove composite heat dissipation substrate” breaks through traditional heat dissipation limits, ensuring stable power generation throughout the entire lifecycle of photovoltaic systems;

- Millisecond-level protection: Technology developed based on IEC 60747-2 establishes an “intrinsically safe” defense line for the DC side of power plants;

- Environmental adaptability: The patented sealed structure and salt fog-resistant alloy materials have passed salt fog corrosion tests, making them the “reliable heart” of extreme scenarios such as offshore photovoltaic and desert power stations.

“Bauart Mark certification is synonymous with ‘German rigor.’ Liu Jing's products have passed a full-process production system audit, proving their ability to consistently deliver top-tier international quality.”

Pragmatic Innovation: Transforming Patents from Paper to Practical Applications, Serving Real-World Energy Scenarios

Liu Jing upholds the pragmatic philosophy of “innovation rooted in application, technology aligned with demand”:

✅ Scenario-Based Innovation: Tailored solutions for reverse diode clusters developed to address differentiated needs such as high salt fog in South Korean offshore PV and extreme heat and dust in Middle Eastern deserts, ensuring efficient operation of global renewable energy projects;

✅ Smart Manufacturing as a Service: Digital factories enable direct customer demand to production lines, with dynamic testing via automated test lines.

✅ Closed-Loop Service: Service centers established in Germany, Europe, South Korea, and the Middle East provide “48-hour response + full lifecycle data tracking,” making service a “value-added engine” for customer benefits.

Committed to service-driven development: Building a green energy community starting with certification

This certification marks a key milestone in Liu Jing's global strategy:

Standard breakthrough: TÜV Bauart Mark certification for anti-reverse diodes compliant with IEC 60747-2 standards, clearing barriers for domestic core components to enter international markets;

Ecosystem co-creation: Collaborating with TÜV Rheinland to advance industry safety standards and reduce operational risks for global power plants;

Service Empowerment: Launching the “Green Device Escort Program” to provide technical training and spare parts support for photovoltaic projects in developing countries, ensuring that innovative achievements benefit more communities.

Precision Manufacturing for a Cooler Planet

Every stable operation of an LJ-MD anti-reverse diode contributes to reducing carbon emissions for the planet: “Our mission is not only to manufacture components but also to safeguard clean energy with cutting-edge technology. When global photovoltaic power plants reduce their failure rate by 1% due to our products, it is equivalent to reducing a significant amount of CO₂ emissions annually—this is the ‘temperature’ of precision manufacturing and the commitment to ‘benefiting humanity.’”

The dual certification of Delixi and LJ-MD reflects China's manufacturing industry's transition from “compliance” to “leadership.” Driven by the mission of “helping cool the Earth,” LJ-MD is leveraging its patent-based technological strength, pragmatic innovation, and global service capabilities to become an indispensable “Chinese core” force in the new energy era!

LJ-MD adheres to the core philosophy of “Precision Manufacturing, Cooling the Earth.” Since its establishment, the company has focused on innovation in power semiconductor technology. By using reliable products to reduce energy loss and stable operations to enhance power generation efficiency, it fulfills its commitment to “benefiting humanity.”
