At the 139th China Import and Export Fair (Canton Fair) held in Guangzhou in April 2026, SINGI, a national high-tech enterprise dedicated to low-voltage electrical solutions, made a grand debut with its full range of core DC products. Showcasing a product matrix featuring green intelligence, reliable safety, and technological leadership, SINGI demonstrated the robust strength of Chinese electrical manufacturing to global buyers and continued to expand its footprint in the overseas new energy market.

At this exhibition, SINGI centered on the core demands of the new energy sector, presenting a comprehensive lineup of DC products covering applications in photovoltaics, energy storage, charging piles, and more. Each product embodies SINGI's relentless pursuit of electrical safety and performance optimization.

As a core protective component for DC power distribution systems, SINGI DC MCBs support a wide voltage range of DC 500-1500V with a maximum rated current of 125A. They are perfectly suited for overload and short-circuit protection in high-voltage DC scenarios such as PV modules and energy storage battery packs. Made of high-flame-retardant eco-friendly materials, these breakers feature superior arc-extinguishing capability and aging resistance, and have obtained multiple international certifications including CE, CB, and UKCA, ensuring stable operation even under extreme working conditions and securing the first line of defense for new energy systems.

Addressing the vulnerability of new energy systems to lightning strikes and voltage fluctuations, SINGI DC SPDs adopt advanced metal oxide varistor technology, boasting high energy absorption and low residual voltage to effectively suppress surge voltages and protect core devices like PV inverters and energy storage equipment. Complementary DC Fuses are precisely tailored to DC system fusing characteristics for accurate overcurrent protection, working together to build a comprehensive electrical safety protection system.

The on-display external/internal DC Disconnectors, with a maximum rated voltage of 1500V, feature manual disconnection and visible breakpoints, meeting safety specifications for PV system maintenance and operation. Meanwhile, SINGI also showcased smart products compatible with DC systems, such as WiFi switches and AFDD (Arc Fault Detection Devices), enabling visual, intelligent management of DC power distribution systems through real-time monitoring and accurate early warning, aligning with the global trend of smart electrical development.

Tailored for safe operation and maintenance of PV power stations and large-scale energy storage systems, SINGI's RSD series comes in multiple specifications including 24Vdc and PLC, supporting 1-in-1 and 1-in-2 wiring configurations. With a maximum allowable input voltage of 80V and a maximum input current of 30A, these devices can quickly cut off DC circuits in emergencies, reducing system voltage to a safe threshold in compliance with international PV safety standards, significantly enhancing the operational safety of large new energy projects.

As a global electrical manufacturer with an annual production capacity exceeding USD 100 million, SINGI has always adhered to technology-driven innovation. The company operates 3 production bases with over 20 automated production lines, equipped with more than 300 sets of professional production and testing equipment, and has established a sound quality control system. It has obtained ISO 9001/14001/45001 international triple system certifications, holds over 50 core patents, and exports products to more than 70 countries worldwide, serving as a core supplier for renowned domestic and international enterprises such as ABB and Chint.

All DC products on display have passed rigorous environmental adaptability tests, suitable for complex working conditions such as high altitude, extreme cold, and high salt spray. They also support ODM/OEM customized services, accurately meeting the personalized needs of overseas customers in various fields including utility-scale PV power stations, residential energy storage, commercial and industrial energy storage, and charging piles.

At the Canton Fair, SINGI's DC product series attracted extensive attention from global buyers with its superior quality, complete certification system, and professional customized services. From Southeast Asian PV power station projects to European energy storage system deployments, from American charging pile supporting facilities to African new energy infrastructure, SINGI continues to provide safe, efficient, and green electrical solutions for the global new energy sector with its DC product line as the core.

In the future, SINGI will continue to deepen its focus on DC technology, continuously optimize product performance and expand application scenarios, and contribute to the global green low-carbon transition with more cutting-edge technology and high-quality services, bringing Chinese green electrical technology to every corner of the world.
