Through integration with smart meters and HEMS, Deye’s solution applies AI-driven optimisation by combining weather forecasts, time-of-use electricity pricing, and user consumption patterns to continuously refine charging and discharging strate - gies, improving self-consumption while reducing electricity costs. Deye has recently achieved dual certification for ECHONET Lite and ECHONET Lite AIF, marking a significant milestone in its residential energy storage solution. This certification en - ables Deye systems to seamlessly integrate with Japan’s main - stream HEMS platforms and smart home ecosystems. With this integration, users can now manage air conditioning, light - ing, photovoltaic systems, and energy storage through a single unified interface, eliminating compatibility concerns and en - abling truly intelligent, connected energy management across the home. This development comes at a critical time as Japan accelerates its transition toward smarter and more sustainable housing. Following the release of the 2025 GX ZEH definition, battery storage systems and HEMS are increasingly becoming stan - dard configurations rather than optional upgrades, signalling a shift from selective adoption to structural demand. At the same time, the rise of Virtual Power Plant (VPP) models and the growing demand for real-time energy visibility and control are reshaping how households interact with energy, making centralised and app-based management of home devices a new everyday standard. As the “universal language” of Japan’s smart home ecosystem, ECHONET Lite plays a vital role in enabling interoperability among devices from different manufacturers, allowing them to be recognised and controlled within a unified system. This transforms residential energy storage from a simple backup solution into a core energy hub capable of intelligent schedul - ing and participation in broader energy ecosystems. Through integration with smart meters and HEMS, Deye’s solution applies AI-driven optimisation by combining weather forecasts, time-of-use electricity pricing, and user consumption patterns to continuously refine charging and discharging strat - egies, improving self-consumption while reducing electricity costs. By leveraging real-time data and intelligent algorithms, the system dynamically adjusts energy usage to align with both ex - ternal conditions and user habits, ensuring that energy is used more efficiently throughout the day. This not only enhances overall system performance but also delivers tangible cost sav - ings and a more sustainable energy profile for households. Beyond efficiency, the system also enhances household resil - ience by enabling coordinated responses during power outag - es. When an outage is detected, the system can automatically switch to off-grid mode to ensure continuous power supply for critical loads, while users retain the flexibility to manage ener - gy distribution through centralised control interfaces, making more effective use of limited stored energy during emergencies. Since being recommended by Japan’s Ministry of Economy, Trade and Industry in 2012, ECHONET Lite has expanded from residential applications into commercial buildings and broader IoT ecosystems, becoming a foundational standard for smart energy integration in Japan. This dual certification re - flects Deye’s strong commitment to aligning with international technical standards while simultaneously addressing the specif - ic requirements of localised markets such as Japan. As a global provider of photovoltaic and energy storage solu - tions, Deye continues to deliver systems that are more flexible, intelligent, and user-centric by integrating into mature smart home ecosystems and translating advanced clean energy tech - nologies into practical value for everyday life.
