The project overcame challenges such as off-site construction and climate adaptation, fully demonstrating the "turnkey" full-cycle service capability from equipment supply, site construction to commissioning and grid connection, highlighting that the company's project execution and service network possess the strength to cover the national market.
Industry Recognition! Homsun Electric Storage Appointed as Director Unit of Ronggui Sub-district High-tech Enterprise Innovation Association
Homsun Electric Storage was officially appointed as a Director Unit of the Ronggui Sub-district High-tech Enterprise Innovation Association in Shunde District, Foshan City, marking high recognition of its technological innovation strength and industry contribution by the local government and industry platforms. This status will help the company enhance brand credibility, deeply participate in regional innovation decision-making, and link high-quality industrial resources, providing important platform support for future development.
PV-Storage Microgrid Model Successfully Addresses Challenges of New PV Policies
In response to the new national policy on distributed PV subsidy phase-out in May 2025, Homsun Electric Storage successfully implemented an intelligent PV-storage microgrid project featuring "PV self-generation for self-use + energy storage dynamic dispatch" for Zhongshan Jingguang Gas Appliance Company. The solution achieved 100% local consumption of energy and peak-valley arbitrage through EMS intelligent control, increasing the customer's annual revenue to 205,000 yuan (an increase of about 120% compared to the traditional model) and shortening the investment payback period to 2.85 years, becoming a benchmark case for the company creating value for customers under policy changes.
Homsun Electric Storage Appears at the 17th World Solar Photovoltaic and Energy Storage Industry Expo
Homsun Electric Storage made a brilliant appearance at the 17th World Solar Photovoltaic and Energy Storage Industry Expo (PV Guangzhou 2025), focusing on displaying core products and solutions such as industrial and commercial energy storage cabinets and residential energy storage cabinets to professional audiences from around the world. During the exhibition, booth consultations and negotiations were active, and preliminary cooperation intentions were reached with multiple enterprises, effectively enhancing the brand's international popularity and laying a solid foundation for subsequent market expansion.
Customized Residential Energy Storage Solutions, Demonstrating Flexible Adaptability
Homsun Electric Storage successfully delivered a customized residential energy storage project, tailoring a 144kWh large-capacity energy storage solution for a client who had already installed 40kW of PV but faced electricity wastage. The project cleverly solved the installation challenge on a high-rise rooftop by selecting small-volume energy storage products, achieving 100% self-generation and self-consumption of PV power and reliable backup power for important household equipment, fully demonstrating the company's flexible customization and efficient delivery capabilities in complex scenarios.
Xunzhan BP Gas Station PV-Storage-Charging Integrated Project Successfully Landed!
The Xinxing Xunzhan BP gas station (integrating oil, electricity, PV, and storage) officially opened, placing extreme demands on project safety and equipment quality. Homsun Electric Storage became the core constructor of the station's PV-storage-charging system. The project successfully withstood a super typhoon before opening and operated stably without faults, powerfully proving the high reliability and safety quality of Homsun's products in extreme environments.
200 Units of 16kWh Home Energy Storage Battery Export Order Successfully Shipped!
Homsun Electric Storage successfully shipped an export order for 200 units of 16kWh home energy storage batteries to overseas markets. These products were specially developed for local market demands, featuring compact volume, high energy density, and equipped with low-voltage battery packs. They are widely compatible with mainstream inverters on the market, with outstanding environmental adaptability and system integration flexibility. In the same period, the company completed the R&D of the 10kWh model of the same series. This marks the company's independent R&D and flexible customization capabilities in the residential energy storage field gaining international market recognition, laying an important foundation for expanding the global home energy storage market.
Large-capacity PV-Storage-Charging Integrated Machine Order, Completing the Product Line
Homsun Electric Storage received an order for three-phase low-voltage residential energy storage products. This product is a PV-storage-charging integrated machine with a battery capacity of 70-80kWh and a built-in hybrid inverter, supporting direct DC connection on the PV side. The high capacity configuration can meet the daily electricity and backup power needs of large-power households or small individual industrial and commercial users, further enriching the company's product portfolio for high-end residential and light commercial scenarios, reflecting the company's technical integration capability in integrated and intelligent residential storage solutions.
Homsun Electric Storage's 1365kWh energy storage project will be applied in offshore aquaculture scenarios. This project is an off-grid system where the energy storage cabinets need to connect directly to the PV array as the sole power source; therefore, the products are specially equipped with hybrid inverters, enabling integrated PV DC-side charging and off-grid inverter power supply. Aiming at the harsh environment of high humidity and high salt spray at sea, as well as customer requirements for high reliability and easy maintenance, the energy storage cabinets for this project adopted an air-cooled thermal management design. The solution has a simpler structure, offering higher maintenance convenience in the marine environment and easier replacement of key components.
Homsun Electric Storage Successfully Won the Bid for Guangdong Shunkong 5.3MWh Energy Storage Project
Homsun Electric Storage successfully won the bid for the energy storage project of a wholly-owned subsidiary of Guangdong Shunkong Development Co., Ltd. (listed state-owned enterprise, stock code 003039), providing 11 SP-482kWh energy storage cabinets (total capacity 5.3MWh) for the Huaxin Color Printing factory area. This cooperation with a leading local urban environmental service enterprise marks the full trust of authoritative state-owned capital and high-end customers in the company's technical solutions, product quality, and project delivery capabilities, representing a major milestone in annual market expansion.
