Changsong Electric Showcases at the 3rd Jiangxi Distributed PV-Storage Development Forum
In Nanchang, as the first hints of autumn emerged in September, the momentum of the solar-plus-storage industry continued to surge. On September 22, 2026, the 3rd Jiangxi Distributed Solar-plus-Storage Development Forum—themed "Gathering Energy in Jiangxi, Achieving Win-Win Results in Solar-plus-Storage"—was grandly held at the Shangri-La Hotel, Nanchang. As a specialist deeply rooted in the field of new energy grid-connection and power distribution, Changsong Electric participated in the forum, showcasing core products such as PV grid-connection cabinets, combiner boxes, and prefabricated cabins, alongside comprehensive grid-connection solutions for diverse application scenarios. The company joined industry peers from Jiangxi and across the nation to discuss new opportunities for the development of distributed solar-plus-storage.
I. Forum Background: Jiangxi’s Solar-plus-Storage Market Enters a Critical Phase of "Grid Integration and Revenue Restructuring"
The year 2026 marks the convergence of the launch of the "15th Five-Year Plan" and the conclusion of Jiangxi's "1269" Action Plan; the province's new energy industry is transitioning from a phase of scale expansion to a new stage that places equal emphasis on grid integration, system regulation, market trading, and value restructuring. In the first half of 2026, Jiangxi added 1.307 million kilowatts of distributed photovoltaic (PV) capacity—including 861,000 kilowatts of industrial and commercial PV—establishing distributed PV as a rapidly growing component of the province's power supply.
On the policy front, the Jiangxi Provincial Development and Reform Commission issued the *Implementation Rules for Bidding on Mechanism-Based Tariffs for Incremental New Energy Projects (Revised Edition)* on August 19. By removing the clause from the draft version that excluded commercial and industrial distributed photovoltaic projects from the mechanism-based tariff scheme, Jiangxi became the only province in China to "raise the axe" against these tariffs only to "put it down" again. Meanwhile, independent energy storage and direct connections for green electricity have emerged as two definitive pillars of new energy development in the province; as of the end of June 2026, 47 advanced energy storage projects had been fully connected to the grid, with a total capacity of 1.386 million kW / 2.842 million kWh.
This forum brought together stakeholders from government, industry, academia, research institutions, and the financial sector. It focused on core topics such as the restructuring of project returns amidst shifting electricity pricing mechanisms, the practical implementation of industrial and commercial solar-plus-storage and integrated solar-storage-charging systems, business models for independent energy storage, pathways for direct green power procurement, and zero-carbon industrial park practices. In doing so, it established an efficient platform for policy interpretation, technical exchange, project collaboration, and resource matching.
II. Changsong Electric’s booth draws a massive crowd; professional explanations keep visitors engaged.
On the day of the forum, the Changsong Electric booth—situated in the heart of the venue—drew a steady stream of interested visitors. The physical equipment neatly displayed at the booth, including grid-tie cabinets, grid-connection boxes, and combiner boxes, attracted numerous industry professionals who paused to examine them closely.
"What is the response time for the anti-islanding protection on this grid-connection cabinet? Are the local power supply companies in Jiangxi strict about the acceptance inspection?" asked the manager of a local commercial and industrial PV project in Nanchang, getting straight to the point. The on-site technician immediately opened the cabinet door and pointed to the internal anti-islanding protection device, explaining, "Our grid-connection cabinet fully complies with national standards; it reliably disconnects within two seconds of a grid power loss. Furthermore, it utilizes a dedicated hardware protection device rather than relying on makeshift inverter software. We have all the necessary CQC certifications and type-test reports, so you won't have to worry about acceptance inspections by power supply bureaus across Jiangxi." The manager nodded, immediately took a photo of the component layout inside the cabinet with his phone, and added the technician on WeChat to arrange a follow-up discussion on specific project plans after the exhibition.
"What is the maximum number of input channels this combiner box supports, and what is its protection rating? Given the high temperatures and humidity in Jiangxi during the summer, how well does it handle corrosion and lightning protection?" asked another manager of a distributed PV EPC project from Ganzhou. A staff member explained: "Our PV DC combiner boxes offer configurable input options ranging from 4 to 24 channels and feature an IP65 protection rating for outdoor use. They come standard with components from CHINT and Delixi, and incorporate multiple internal safeguards—including specialized PV fuses, circuit breakers, and lightning protection devices—to fully meet the operational requirements of Jiangxi's hot and humid environment." The EPC manager showed keen interest in the product's lightning and corrosion protection designs, inquired in detail about delivery lead times and warranty terms, and left their contact information.
"For a 500kW commercial and industrial project, which grid-connection cabinet model do you recommend under the new electricity pricing regulations? How should the anti-reverse power flow function be configured?" asked a distributed PV investor from Jiujiang while consulting at the CSGGD PV grid-connection metering cabinet display. Taking into account the project's capacity and the requirements of Jiangxi's new pricing policy, the on-site representative provided a detailed explanation regarding the selection of the cabinet's rated current, the configuration of the anti-reverse power flow function, and the metering scheme, while also offering preliminary configuration recommendations. The investor noted that, having compared several suppliers, they found Changsong Electric’s configurations for anti-islanding protection and bi-directional metering to be superior and its understanding of local Jiangxi policies to be thorough; consequently, they expressed a willingness to discuss further details regarding potential cooperation.
At one corner of the booth, several energy storage system integrators from Shangrao showed keen interest in the prefabricated container and step-up transformer substation products. They inquired in detail about the products' ingress protection ratings, operating temperature ranges, and integration solutions for energy storage systems. After the staff provided comprehensive answers, the visitors mentioned they were currently advancing a standalone energy storage project with significant demand for grid-connection and distribution equipment; it was agreed that technical proposals would be sent after the exhibition for further discussion.
Throughout the forum, the Changsong Electric booth drew a steady stream of visitors. Inquirers represented a diverse range of groups, including local PV EPC contractors in Jiangxi, owners of industrial and commercial projects, energy storage system integrators, and industry distributors. Technical staff and the sales team worked in tandem, explaining product specifications and technical advantages while noting down specific project requirements; the booth's discussion area remained packed with visitors. Following detailed consultations, many clients expressed a clear intent to collaborate on the spot, arranging for technical proposals and formal quotations to be sent after the event.
According to the on-site representative from Changsong Electric, customer inquiries at the forum centered on three key areas: first, changes in grid-connection cabinet configurations necessitated by new policies on market-based electricity pricing—specifically, how to align anti-backflow functions and metering schemes with these new requirements; second, compliance regarding anti-islanding protection and grid-connection acceptance—a critical threshold for successful project interconnection, given the increasingly stringent standards enforced by local power supply companies in Jiangxi; and third, product lead times and customization capabilities, as many commercial and industrial projects have specific requirements regarding delivery schedules and non-standard specifications. The Changsong Electric team provided professional, detailed responses to these frequently raised issues, along with preliminary product selection advice and indicative pricing, earning widespread recognition from customers.
