Among the showcased solutions, the off-grid combination of the SUN-6K-OG02LP1 inverter with the SE-F battery system demonstrated a dependable and adaptable approach for areas with limited or unstable grid access. Featuring up to 200% PV oversizing and a 36A PV input supporting dual strings, the system captures more solar energy under varying sunlight conditions. Engineered for stability in daily operation, the system delivers up to 135A charge and discharge current, supporting consistent energy flow for a wide range of applications, such as remote cabins, mobile clinics and backup power for rural industrial sites. In addition, its 97.6% conversion efficiency helps maximize usable energy, while a 4ms ultra-fast switching time ensures seamless power transition, making it suitable for sensitive loads that require uninterrupted supply.
For residential ESS, Deye once again demonstrated its innovation and comprehensiveness with its all-in-one ESS RW-F5.3-1H3. This wall-mounted unit, combining a 5kW hybrid inverter and a 5.3kWh LFP battery, drew significant attention, particularly from European visitors. “This all-in-one machine is a great choice for home storage—it's compact, silent, and easy to install,” remarked one attendee, echoing a common sentiment at the booth. The space-saving design supports both indoor and outdoor installation with an IP65 rating and a wide operating temperature range of -20°C to 55°C (with optional heating). Natural cooling eliminates the need for fans, enabling silent, maintenance-free operation. The built-in intelligent BMS delivers complete protection, while the system achieves over 6000 cycles with 80% end-of-life capacity retention, ensuring long-term reliability.
For commercial and industrial applications, apart from previous star solutions such as BOS-G Pro + SUN-30K-SG02HP3, Deye unveiled its new product – the SUN-100/125K-SG02HP3 three-phase high-voltage hybrid inverter for large C&I energy storage. Designed to help businesses optimize energy usage and accelerate the transition toward sustainable power systems, the inverter supports a wide high-voltage battery range and delivers fast charging and discharging capabilities for peak-shaving, backup power, and demand management. Equipped with up to 10 MPPT trackers and a high PV input voltage, it captures solar energy effectively even in complex rooftop or ground-mounted installations, while allowing substantial PV oversizing to maximize system yield.
Built for demanding environments, the inverter features IP65 protection, intelligent air cooling, and reliable operation across extreme temperatures. It supports AC coupling for seamless retrofitting of existing PV systems, and up to 10 units can operate in parallel for scalable expansion in both on-grid and off-grid scenarios. When paired with Deye's GE-F240/F256 battery cabinets, the system forms a highly integrated all-in-one solution supporting PV, grid, battery, and diesel generator connections within a single cabinet. Backed by a 24/7 AI-driven energy platform, users can optimize power usage strategies, enhance system efficiency, and achieve greater long-term energy savings.
Deye’s presence at the Canton Fair not only reinforced its position as a key player in the global energy storage industry but also provided a valuable platform for strengthening partnerships and exploring new market opportunities. Moving forward, Deye will continue to innovate and expand its product portfolio, contributing to the global transition toward cleaner and smarter energy systems.
