One System, Every Need — From Essential Backup to Whole-Home Power
Deye’s All-in-One Home ESS is a fully integrated PV + storage solution.With its modular stackable design, each inverter module can connect 1 to 6 battery packs, and a maximum of 3 inverter modules are supported for parallel connection, forming a system with a maximum capacity of 16×6×3 = 288 kWh. Combined with 10 inverter model series ranging from 3.6–12 kW single-phase and 5–20 kW three-phase, the system covers virtually every residential scenario — from compact apartments to large standalone villas.
From partial backup power supply to whole-house backup power supply and 100% self-consumption- just add modules:
3.6–6kW Single-Phase:Powers lighting, refrigerators, routers, and other daily essentials to keep life running during outages;
6-12kW Single-Phase / 5-12 kW Three-Phase: Supports air conditioners, washing machines, water heaters, and more high-power appliances for enhanced comfort;
12-20kW Three-Phase: Full-home power coverage, even handling EV chargers (up to 7 kW) — truly enabling energy independence.
Four Core Breakthroughs That Reset the Standard for Residential Storage
① Higher Cost-Efficiency: 16 kWh Large Modules Reduce System Cost by ~20%
Unlike the common 8 kWh stacking solutions on the market, Deye’s new All-in-One system features 16 kWh per module. At the same total capacity, the overall system cost is approximately 20% lower than traditional 8 kWh stacked configurations, making the PV-plus-storage lifestyle accessible to more households.
② Lower Standby Loss: DC-DC-Free Design Means Negligible Draw
Thanks to the innovative DC-DC-free architecture on the battery side, the system’s tandby power consumption is dramatically reduced — not only cutting daily energy waste but also significantly extending the battery’s shelf life, for greater peace of mind and long-term savings.
③ Tougher Environmental Adaptability: IP66 Outdoor Rating, Built for Rain, Snow, and Cold
The entire system carries an IP66 protection rating, allowing direct outdoor installation and saving valuable indoor space. Notably, it can withstand short-term immersion in 0.5 meters of water, remaining reliable even in extreme weather conditions like heavy rain, snowstorms, or temporary flooding.
With the optional heating module, the battery can charge at temperatures as low as -20℃—whether it’s a Nordic winter or a tropical monsoon region,the Deye All-in-One ESS delivers stable power you can count on.
④ Wireless Zero-Feed-In: LoRa Technology for Smart Management Without Internet
Deye’s proprietary off-grid wireless zero-export solution based on LoRa technology uses CT current transformers to monitor real-time electricity data. Even in environments without internet access, intelligent energy management and zero-feed-in control are fully operational — simpler to install, lower in cost, and higher in reliability.
