At the 18th SNEC International Solar Photovoltaic and Intelligent Energy Conference and Exhibition held recently, the Digital New Energy DataBM. Com interviewed Song Zehao, Vice President of Marketing Center of Sanyou Lianzhong Group Co., Ltd. In the interview, Mr. Song shared the practice and planning of the enterprise in technological innovation, integrated application of "photovoltaic + energy storage ", and global strategic layout. In the construction of
photovoltaic power plants, relays may not be surprising, but they are the core components of photovoltaic inverters and energy storage inverters. They not only play the role of switches in inverters, but also control power on-off by virtue of their rapid response ability, so as to accurately regulate power transmission; At the same time, it plays a necessary "circuit breaking" function in the inverter circuit to ensure that the circuit can be cut off under sudden abnormal conditions such as overload, short circuit and overvoltage, so as to avoid damage to the circuit and equipment. Therefore, the relay plays a vital role in ensuring the safety and efficiency of the power generation system of the power station. As a high-tech enterprise specializing in R & D, design and manufacturing of relays, transformers and plug-in inductors
, Sanyou Lianzhong's products in the field of relays cover photovoltaic, high-voltage DC, magnetic latching, signal, automotive low-voltage, general relays, supporting wind and solar storage, power grid and other applications.
In addition, under the trend of "photovoltaic + energy storage" integration, Sanyou Lianzhong relies on its technological advantages to help the system and the grid work efficiently.
According to Song Zehao, in the field of new energy, Sanyou Lianzhong products have long served the four major power links of "generation-storage-distribution-utilization". In the inverter link of the photovoltaic power station and the energy storage system , the large GAP photovoltaic relay and the high-voltage DC relay for the switch of the distribution box are provided; for the energy storage field, the signal relay for insulation monitoring, cell equalization and battery main circuit control is provided.
"When the electric energy is injected into the city grid, the magnetic latching relay in the smart meter ensures the stable and continuous operation of the grid switching with extremely low static energy consumption and extremely high on-off life, and finally forms a complete supporting scheme of the generation-storage-distribution-utilization system to realize the efficient utilization of energy." Song Zehao introduced to the Digital New Energy DataBM. Com. During the exchange, Song Zehao stressed to reporters that Sanyou Lianzhong not only sells "products", but also delivers "value" and provides "solutions".
With the wave of "going to sea", optical storage enterprises have actively accelerated the pace of overseas market layout in recent years. As a supporting industrial chain enterprise, in 2024, Sanyou Lianzhong also took the first step to go to sea, and the Vietnam factory has been officially put into operation.
In the next few years, the global integration layout will remain an important strategy for Sanyou Lianzhong. Song Zehao said that the company will continue to cultivate new energy, rail transit and intelligent manufacturing in China, while laying out localized R & D and service networks in key regions such as Europe, America and Southeast Asia, and ultimately achieve the goal of 50% revenue at home and abroad.
