From November 13th to 15th, 2025, the 17th Wuxi International New Energy Exhibition was held grandly at the Wuxi Taihu International Expo Center. Marking this significant event, Zhejiang Chint Xinhui Photovoltaic Co., Ltd., a high-tech enterprise specializing in green power connectors, cable harnesses, and PV module junction boxes, made a prominent appearance. Under the theme "Energy and Carbon Future · Green Power for the Globe," the company showcased multiple innovative achievements, comprehensively displaying its cutting-edge technologies, high-efficiency products, and sustainable strategies. During the exhibition, Chint Xinhui's booth (A3-322) was a hive of activity, with a steady stream of clients and partners engaging in in-depth and dynamic discussions with the company's leadership, sales team, and technical experts.
At this international industry event that gathered top global enterprises, Chint Xinhui, as a drafting unit for several national industry standards including those for PV junction boxes and connectors, remains committed to leading industry development through technological innovation. The company focuses on reducing costs and improving efficiency in power plant and new energy connection systems, providing customized green power connection solutions for customers, including solutions for balcony photovoltaic systems.
The exhibition featured two major innovative product lines:
1. New Products for Cost Reduction and Quality Enhancement
The new junction box products include quarter-cut cell module junction boxes and BIPV module junction boxes, offering valuable additions for module manufacturers seeking differentiated competition. New power plant harness products include the HCC40 connector, PV fuse harnesses, copper-aluminum connection harnesses, new board-end connectors, and energy storage connectors. Breakthroughs in material innovation and overcoming the technical challenges of copper-aluminum transition connection have secured multiple invention patents. These advancements empower the Chint brand to develop and lead the power plant harness market, continuously contributing to improved power plant quality and returns.
2. New Products for Intelligence and Safety
For the residential, commercial, and industrial markets, new smart optimizers and rapid shutdown devices were launched, representing industry-leading levels. The smart optimizers can increase power generation by 10% to 30% for customers. When used with rapid shutdown device harnesses, they enhance system generation efficiency while ensuring electrical safety. In 2025, Chint Xinhui has transformed from a sole junction box manufacturer into a provider of integrated PV connection harness systems. With a daily production capacity of 200,000 sets for junction boxes and connectors, along with new automated equipment, leading processes, quality, and cost advantages, the full product range leverages technological innovation to help PV power plants achieve efficient, intelligent, and reliable operation.
Chint Xinhui PV Connection Systems: The Safe and Efficient "Cornerstone"
At this exhibition, Chint Xinhui displayed its full series of green power connection products, including PV junction boxes, various types of connectors, smart power plant harnesses, and specialized connectors designed for energy storage systems and inverters. Our product lines attracted numerous professional clients for consultations, fostering a vibrant atmosphere for on-site exchange.
PV-SO1 Smart Optimizer:Fully adaptable to different power requirements, with power gradients of 800W/700W/600W. It operates stably even under extreme conditions of 80°C high temperature and full load, demonstrating excellent safety performance. Integrating 7 core protections and 2 additional functions, it provides comprehensive system security. Through precise module-level MPPT optimization (efficiency up to 99.9%), it effectively eliminates mismatch losses in series connections, achieving up to 30% increase in power generation.
PV-Yx Branch Connection Harness (Copper/Aluminum):Protection rating reaches IP65/IP68. It uses potting seals and anti-aging housing for a long service life. The crimping process ensures safe and reliable connections, and the lug-style design facilitates easy installation. It supports high current (up to 54A) and various customized solutions, flexibly meeting the demands of high-power scenarios.
PV-HCC40 Line-End Connector:For safety, it employs a triple-insulation structure comprising a circumferential groove, tail fin, and internal sheath, ensuring secure and reliable electrical performance. It also features excellent compatibility, allowing quick mating and compatibility with mainstream products like MC4, while retaining traditional advantages such as high current capacity and high sealing, making it suitable for PV systems in all scenarios.
PV-HCB50 Copper-Aluminum Connector:Its core lies in the industry's pioneering "two-stage crimping" process, successfully resolving the technical challenge of bridging aluminum wires with copper/aluminum wires. This not only ensures high safety of electrical connection (tin plating process, tight riveting, IP68 protection) but also enables convenient mating with mainstream MC4 connectors. It maintains the same high performance as traditional copper connectors (high current, high sealing) while achieving significant cost reduction and efficiency gains through the application of aluminum material.
Aligning with the '16th Five-Year Plan' Direction, Making PV the Mainstay in the Era of 'Energy-Carbon Synergy'
As the curtain rises on the "16th Five-Year Plan" period (2026-2030), a new era of green, smart, and efficient energy is approaching. Zheng Shanjie, Secretary of the Party Leadership Group and Minister of the National Development and Reform Commission, responding to inquiries about measures to promote the green transformation of key industries and the low-carbon transition of the energy structure, stated that the "Proposal of the Central Committee of the Communist Party of China on Formulating the 16th Five-Year Plan for National Economic and Social Development" makes systematic部署 for accelerating the comprehensive green transformation of economic and social development, wherein both industrial transformation and energy transition are top priorities.
Chint Xinhui actively seizes industry trends with innovation at its core. No longer confined to traditional connection components, the company is dedicated to integrating green power connection systems with new technologies, actively incorporating AI algorithms and intelligent power electronics technologies. It has currently launched a series of smart products like smart optimizers and rapid shutdown devices, creating safer, more efficient, and smarter green energy value for end customers.
Leading Green Power Connections with Innovation, Building the Foundation for the Global Energy Future
Confronting the accelerating tide of global energy transition, Chint Xinhui consistently uses innovation as its engine, striving to become a global leading provider of green power connection system solutions.
