Topband Showcases Ecosolex Sub-Brand at Solar & Storage Live Vietnam 2025, Deepening Market Presence Through Localization
[Ho Chi Minh City, July 9, 2025] — Solar & Storage Live Vietnam 2025, Vietnam's premier energy industry event, kicked off today at SKY EXPO in Ho Chi Minh City. Topband Co., Ltd. (002139.SZ) participated with its renewable energy sub-brand, Ecosolex, presenting a comprehensive suite of customized residential and commercial & industrial (C&I) energy storage system solutions designed specifically for the Vietnamese market. Leveraging its signature "One Core, One Cloud, 3S" technology and deep localization strategy, Topband and Ecosolex attracted significant attention and business discussions from numerous industry professionals at the event.
Addressing Market-Specific Challenges: Tailored Technical Solutions for Vietnam
Vietnam's energy transition faces unique dual challenges: its abundant solar resources provide excellent conditions for photovoltaic development, while its hot and humid climate, occasional grid fluctuations, and rapidly growing electrification trends impose stringent demands on the safety, efficiency, and reliability of energy equipment.
The products highlighted by Topband at the exhibition are specifically designed to address these challenges:
The 215kWh liquid-cooled and 100kWh air-cooled C&I energy storage systems, designed to enhance grid resilience, utilize high-safety standard battery cells and incorporate a robust environmental adaptation design. This enables them to effectively withstand Vietnam’s hot and humid climate conditions, providing reliable power backup for factories, commercial complexes, and industrial parks while mitigating the impact of grid fluctuations.
The 60kW DC dual-vehicle fast charging pile supports Vietnam's electrification future with its IP54 enclosure and wide operating temperature range from -20°C to 50°C, ensuring reliable operation in humid and hot environments. Its intelligent dynamic power allocation technology optimizes charging efficiency, delivering efficient and reliable charging services for commercial electric vehicle fleets and public charging stations.
From Products to Partner: Deep Localization Strategy Empowers Vietnam's Energy Transition
Topband firmly believes that long-term success in the Vietnamese market is rooted in deep localized operation. As one of the countries most vulnerable to climate change, Vietnam has set a national target of achieving net-zero emission by 2050. Its Power Development Plan VIII (PDP8) also outlines a clear pathway for its energy transition.
Supporting the achievement of these ambitious goals requires more than just supplying hardware. Topband is actively evolving its role from a "technology provider" to a "joint transformation partner":
Localized Production & Service: Relying on the established production bases and branches in Vietnam, Ecosolex has built a production and service network covering the local area and surrounding areas, which can provide customers with faster product delivery and more agile on-site technical support.
Flexible Customization Capabilities: Based on a modular product design concept, Ecosolex's solutions are highly flexible and can be quickly customized and iterated according to the diverse project needs of Vietnamese industrial and commercial customers.
The systematic capabilities demonstrated by Topband from core components to intelligent cloud platforms are providing solid technical support for Vietnam to achieve its energy goals.
Systematic Layout: Full-Stack Capabilities Drive a New Chapter in Green Energy
Through this exhibition, the signal sent by Topband and Ecosolex is clear: relying on its full-stack R&D capabilities across core components including battery cells, Battery Management Systems (BMS), Power Conversion Systems (PCS), Energy Management Systems (EMS), and the cloud platform (embodied in its "One Core, One Cloud, 3S" technology), the company is actively participating in Vietnam's energy structure transformation.
Moving forward, Topband will continue to invest in R&D and innovation. Grounded in a deep understanding of the Vietnamese market's needs and localized, agile operations, Topband will partner with vietnameses to deliver more stable, cleaner, and smarter energy solutions for this dynamic market, jointly supporting Vietnam in achieving its sustainable development goals.
