When the lights of the Shanghai Photovoltaic and Energy Storage Exhibition illuminated the Pudong Exhibition Hall, Mark White, an inverter manufacturer from Australia, stood in front of Teliang's booth, his eyes firmly attracted by the displayed samples of PCB screw terminals. This industry event in 2025 became the starting point for the encounter between Chinese and Australian new energy enterprises across the hemisphere. Half a year later, the two sides met at the Canton Fair in April 2026. In the exhibition hall by the Pearl River, they had in-depth discussions on cooperation. Teliang's newly developed PCB screw terminals won high recognition from Mark's team with their excellent performance, and a cross-border cooperation based on technological resonance was about to set sail. This is not only a business opportunity linked by two exhibitions but also an accurate match between Chinese intelligent manufacturing and the needs of the Australian new energy market, writing a new chapter of mutual benefit and win-win results in the global energy transition wave.

Mark White's arrival was quite dramatic. As the technical director of a well - known inverter manufacturer in Australia, the core purpose of his trip was to find a highly adaptable PCB screw terminal supplier for the company's new - generation distributed photovoltaic inverters. Australia is rich in solar energy resources, and the distributed photovoltaic market is expanding rapidly at an average annual growth rate of 32%. However, its inverter products have long relied on imported terminals, not only with high procurement costs but also facing problems such as insufficient adaptability and long supply cycles. "We need a PCB screw terminal that can withstand the high - temperature environment in Australia, is easy to install, and has stable electrical conductivity," Mark said frankly at the exhibition. "The products of our previous cooperative suppliers frequently had problems of increased contact resistance under high - temperature working conditions above 45°C, seriously affecting the efficiency of the inverter."

First Encounter in Shanghai: Exhibition Encounter Plants the Seeds of Cooperation

In November 2025, the Shanghai Photovoltaic and Energy Storage Exhibition gathered more than 2,000 enterprises. Teliang participated with a full range of new energy connection products. Among them, core products such as PCB screw terminals and energy storage terminal blocks became the "eye-catching focus" of the booth due to their high reliability and current-carrying capacity.

Mark White, the technical director of a well-known Australian inverter manufacturer, was searching for a highly adaptable PCB screw terminal for new-generation distributed photovoltaic inverters. Australia's distributed PV market is growing at 32% annually, but products frequently face contact resistance issues in temperatures above 45°C. Teliang’s technical staff introduced terminals using high-conductivity copper-alloy with silver-plated surfaces, controlled below 0.03mΩ, and designed for a torque range of 10-15N·m, fully adapting to the Australian savannah climate. This encounter laid a solid foundation for subsequent cooperation.The latest generation of Teliang's PCB screw terminals has won the favor of Australian customers, thanks to its continuous deep - plowing in technological research and development over the years. As a leading enterprise in the new energy connection field, Teliang has always been guided by market demand and carried out product iteration and upgrading for different application scenarios. This PCB screw terminal, aimed at the global high - end market, is the crystallization of technological innovation and scenario adaptation.In terms of material selection, Teliang broke through the limitations of traditional copper materials and selected copper - chromium - zirconium alloy as the conductive core of the terminal. After vacuum heat - treatment, the conductivity of this material is as high as 95% IACS, far exceeding the 65% IACS of ordinary brass, effectively reducing heat loss during large - current transmission. The surface is coated with a nano - scale silver - tin alloy, with the thickness precisely controlled at 3 - 5μm. The anti - sulfidation ability is 5 times higher than that of a pure silver coating, perfectly solving the industry problem of coating oxidation in high - temperature and high - humidity environments. For the extreme temperatures outdoors in Australia, the terminal shell is made of enhanced PA66 engineering plastics. After adding a glass - fiber reinforcing agent, the mechanical strength is increased by 30%, and the flame - retardant grade reaches UL94 V - 0. It can work continuously for 720 hours at 85°C without deformation or aging.

Ingenious Research and Development: The Technological Innovation Path of PCB Screw Terminals

The latest generation of Teliang's terminal blocks is the crystallization of technological innovation. Teliang selected copper-chromium-zirconium alloy as the conductive core. After vacuum heat-treatment, the conductivity is as high as 95% IACS, far exceeding the 65% IACS of ordinary brass. The surface is coated with a nano-scale silver-tin alloy, 5 times more anti-sulfidation than pure silver coating.

In terms of structural design, the screw adopts a double design of a cross-slot and an inner hexagon. The thread uses a fine-thread structure with 40% more effective meshing teeth than traditional coarse-threads. Teliang's laboratory carried out stringent reliability tests: after 5,000 hours in 45°C high temperature and 85% humidity, the contact resistance change rate was ≤5%. These hardcore data became the key confidence to impress Mark's team.

In-depth Discussion at the Canton Fair: Technological Resonance Finalizes the Cooperation Direction

In April 2026, at the 139th Canton Fair in Guangzhou, Teliang showcased its customized solutions. Mark's team noted that Teliang controlled the temperature rise of the terminal within 30K at 50°C, far lower than the industry standard of 50K. Mark put forward specific customization requirements, such as an anti-misplug function and compatibility with two wire-diameter specifications. Teliang responded on the spot, promising customized terminal blocks samples within 15 days.

The two sides reached a preliminary consensus: Teliang will provide 200 sets of customized samples for installation tests. Upon passing, an annual purchase agreement for 50,000 pieces will be signed, marking an important breakthrough in the southern hemisphere market.

Win-win Future: The Broad Prospects of Sino-Australian New Energy Cooperation

Sino-Australian new energy cooperation has a solid foundation. By 2030, Australia's photovoltaic installed capacity will reach 60GW, and the demand for high-quality terminal blocks will continue to surge. Teliang's production capacity of 2 million units per month and 24-hour technical support guarantee this cooperation.

From the first encounter in Shanghai to the in-depth cooperation at the Canton Fair, Teliang’s cross-hemisphere appointment is a vivid epitome of Chinese intelligent manufacturing going global. With joint efforts, Teliang's PCB screw terminals will become core supporting components for Australian inverters, providing solid support for clean energy transition.This cross - border cooperation based on two exhibitions and starting from technological resonance is opening a new chapter of mutual benefit and win - win results in the Sino - Australian new energy industry. It is believed that with the joint efforts of both sides, Teliang's PCB screw terminals will become the core supporting components of Australian photovoltaic inverters, providing solid support for Australia's clean energy transition, and making the brand of Chinese intelligent manufacturing shine under the blue sky and white clouds in the southern hemisphere.
