Liu Minqiang, General Manager of Huawei Fujian Digital Energy’s Smart PV Division, delivered a keynote address at the event.

The newly commissioned Photovoltaic-Energy Storage Integration (PV-ES) project, fully funded by Yudian, represents a groundbreaking innovation in the temperature control industry, marking the first-of-its-kind initiative in this sector. Within the private enterprise landscape of Fujian Province, it stands as a pioneering model for advancing green and low-carbon development.Liu Minqiang  emphasized during the event.

In his remarks, Liu elaborated on Huawei’s technological advancements and market leadership.He said that Huawei’s commercial and industrial inverters have consistently maintained global market leadership in cumulative shipments. In addition, last year Huawei launched the upgraded Industry Green Power Solution 2.0, which features two cutting-edge products: the SUN2000-150K commercial and industrial photovoltaic inverter and the world’s first air-and-liquid hybrid cooling commercial energy storage system. These innovations empower clients across industries to build safer, more reliable, and cost-effective green photovoltaic power stations.”

"Yudian is committed to delivering highly efficient and energy-saving temperature control solutions to support China’s energy transition,” declared Jiang Yanfang, CEO of Yudian Automation. In her remarks, she highlighted,"As a key player in China’s new energy sector, Yudian has systematically prioritized its internal green development strategy, aligning with national environmental goals through a comprehensive sustainability framework. Meanwhile, Huawei Digital Energy, as a global leader in low-carbon innovation, combines cutting-edge technical expertise with industry-leading experience in digital energy solutions. Their flagship products—the SUN2000-150K commercial and industrial photovoltaic inverter and the world’s first air-and-liquid hybrid cooling energy storage system—have set new industry benchmarks. By partnering with Huawei, Yudian will accelerate the construction of safer, more reliable green photovoltaic power stations and industrial parks. Moving forward, we will significantly boost R&D investment in green technologies, upgrade equipment, and explore innovative applications of renewable energy to advance our sustainability commitments. "

At the event, Yudian and Huawei signed a cooperation agreement to facilitate green energy development. Looking ahead, the two parties will join forces to advance corporate green transformation and development, actively implementing China’s "Dual Carbon" goals.

Subsequently, Yudian’s "Photovoltaic-Energy Storage Integration (PV-ES)" project was successfully inaugurated, marking the smooth landing of Huawei’s first nationwide benchmark project for corporate grid-connected and off-grid energy storage at Yudian Temperature Control Technology Industrial Park.

Build a Green Energy Factor

Yudian’s photovoltaic-energy storage project, spanning both the Huli and Xiang'an industrial parks, makes smart use of previously idle rooftop space. By installing 781 solar panels on a 5,000-square-meter factory roof, the company has built a 492kW distributed solar power station paired with a 216kW/430kWh smart energy storage system. Preliminary projections show the integrated system will generate 430,000 kilowatt-hours (kWh) of green electricity annually, avoiding around 420 tons of carbon dioxide emissions each year.

Notably, the energy storage system in Yudian’s PV-ES integration project operates on a grid-connected and off-grid hybrid model. It can store unconsumed solar-generated electricity, providing disaster-resilient protection for critical equipment to ensure uninterrupted production. Additionally, the system leverages smart algorithms to dynamically adjust charging and discharging during peak and off-peak hours, effectively reducing the industrial park’s electricity costs.

 In addition to its investments in photovoltaic energy storage, Yudian has been making concerted efforts to improve employee working environments, promote waste recycling and resource utilization, and strengthen noise control—all part of its commitment to building aneco-friendly factory. The Yudian Temperature Control Technology Industrial Park, built around the principles ofgreen manufacturing and efficiency, began trial production by the end of last year.

specialized in the research of temperature controllers

Internally, Yudian has established an eco-friendly factory benchmark; externally, it helps hundreds of industries achieve energy conservation and cost reduction.Founded in 1991, Yudian has remained steadfastly focused on the research, development, and production of intelligent temperature controllers. For decades, the company has been dedicated to helping manufacturing across all industries achieve energy savings and cost reductions by providing high-quality products and premium services.

In recent years, Yudian has made significant breakthroughs in cascade temperature control technology and related fields, successively overcoming long-standing "bottleneck" challenges in sectors such as semiconductors, photovoltaics, and lithium batteries. These advancements have enabled the company to break foreign technological monopolies in these critical industries.

In the new energy sector, Yudian has collaborated with leading photovoltaic (PV) equipment manufacturers to achieve import substitution for temperature controllers. Through technical upgrades such as increasing heating rates, reducing overshoot, and shortening process cycles, the company has boosted production efficiency by 8%, enhancing both equipment utilization and product yield. These advancements have helped China’s PV industry consolidate its global leading position. Meanwhile, Yudian’s decade-long partnership with top lithium battery enterprises has supported the sector in achieving energy savings and cost reductions. In the semiconductor field—where reliability and performance requirements are extremely stringent—the company has entered the supply chain of leading semiconductor equipment manufacturers. Its superior temperature controllers, designed to meet the industry’s most demanding specifications, are now successfully integrated into semiconductor production processes.

Moving ahead, Yudian will collaborate with more partners to advance low-carbon economies. Leveraging advanced precision temperature control technologies, Yudian will offer efficient and stable thermal management solutions to reduce energy use and production costs, enhance product quality and operational efficiency, and help enterprises achieve energy-saving and efficiency goals. Together, these efforts will contribute to China’s "Dual Carbon" goals.
