As one of Southeast Asia’s most dynamic renewable energy markets, Vietnam represents a strategic opportunity for Deye to support the region’s transition towards cleaner, more resilient energy infrastructure.
A highlight at Deye’s booth was its innovative off-grid residential solution, featuring the robust 6kW off-grid inverter paired with the SE-F5 Neptune battery. Designed for rural areas and remote communities, this system adopts an independent cooling duct design, which reduces dust intrusion and ensures long-term performance stability even under Vietnam’s challenging climate conditions. The SE-F5 Neptune battery, based on high-quality LFP cells and an intelligent BMS, offers excellent safety, extended cycle life of over 6,000 cycles at 70% EOL, and seamless compatibility with Deye’s hybrid and off-grid inverters — delivering reliable energy independence for households.
Addressing the growing demand for urban decentralized energy, Deye also showcased its balcony energy storage system, a compact and user-friendly solution that allows homeowners to harness solar power right from their apartments. This solution demonstrates Deye’s commitment to developing flexible products that empower consumers to actively participate in the energy transition, even in dense urban environments.
For the C&I sector, Deye introduced its advanced 80kW PCS paired with the BOS-W battery system, delivering robust peak shaving, load shifting, and backup power capabilities for factories, schools, and agricultural facilities. Meanwhile, the PCS + BOS-B configuration drew strong attention for its scalability and grid-support functions, offering reliable power management for larger commercial projects that require stable energy supply and maximum operational efficiency.
To further enhance system intelligence and user experience, Deye’s solutions are also supported by an advanced wireless energy manage system. With flexible LoRa configuration, the system enables real-time monitoring, remote parameter adjustment, and smart scheduling for both residential and commercial applications. This allows installers and end-users alike to optimize energy use, reduce operational costs, and ensure stable performance across various scenarios — even in areas with limited network infrastructure.
Another key focus was Deye’s popular SUN-12K-SG05LP3-EU-SM2 inverter integrated with the RW-F16 residential battery, providing homeowners with a highly
efficient hybrid energy storage system that supports self-consumption, backup power, and optimized grid interaction. This flagship solution embodies Deye’s commitment to bringing smart, flexible, and future-ready energy options to households across Southeast Asia.
The company also presented its versatile single-phase and three-phase PV inverter lineup, including models such as the SUN-5K-SG04LP1-EU-SM2, SUN-8K-SG05LP1-EU-SM2-P, SUN-20K-SG05LP3-EU-SM2, and SUN-20K-SG01HP3-EU, all engineered to deliver high efficiency, reliability, and seamless compatibility with various battery configurations.
Deye’s strong showcase at the Vietnam Solar Expo underscores its long-term commitment to supporting Southeast Asia’s renewable energy goals through continuous product innovation and localized service. With its comprehensive range of inverters and storage systems, Deye is well positioned to empower communities and businesses alike to take control of their energy journey.
