The Deye Spring Series (Wall-Mounted Battery LV) is a low-voltage energy storage system designed for fast wall-mount installation and flexible system expansion. Its key advantage is LiFePO4 (LFP) chemistry - compared to NMC, it offers higher thermal stability, better resilience to intensive use, and increased safety in residential and commercial conditions. The intelligent BMS manages battery operation, balances cells, and protects against common risks (overload, deep discharge, overheating).
In practice, high cycle life and long warranty also play a significant role - this translates to truly lower energy costs throughout the system’s lifespan and greater service predictability. The Spring Series supports capacity scaling through module connection, enabling users to start with a basic setup and expand the system as renewable consumption or backup power needs grow. This solution is designed for compatibility with inverters and hybrid systems, as well as off-grid installations, where reliability and easy diagnostics are crucial.

Specifications
Pros and cons
Models from the RW series (e.g., RW-F10.6, RW-F16) are designed to withstand over 6000 cycles at 70% of their final capacity. This translates to over 16 years of operation with a 1-cycle/day usage pattern - significantly exceeding the SolarEdge Battery (~4000 cycles) and being on par with the leading LV segment (Pylontech US5000: ~6000 cycles).
The RW series (wall-mounted) features an IP65 enclosure, allowing for installation on external walls - such as a garage wall or facade - without the need for additional covers. The operating temperature range of -20°C to +55°C is one of the widest among low-voltage residential ESS (Energy Storage Systems).
The RW-F16 (16 kWh) model allows for the connection of up to 32 units, achieving a total of up to 512 kWh in a single installation. The modular design allows for the expansion of an existing system without the need to replace the Battery Management System (BMS) or the main bus wiring.
The series has obtained CE, IEC 62619, UL1973, UL9540, UL9540A, VDE 2510-50, and CB certifications, which allows for distribution in the European, North American, and Australian markets without the need for additional certification by installers.
Deye offers a 10-year warranty on the Spring RW series - which meets tier-1 standards (BYD Battery-Box LV: 10 years, Pylontech: 10 years). This provides predictable Total Cost of Ownership (TCO) and comparable protection to leading brands in the segment.
A nominal voltage of 51.2 V means that at a discharging power of 5 kW, the current is approximately 100 A (compared to ~13 A in 400 V HV systems). This requires cables of ≥25-35 mm², and increases I²R losses. For installations >10 kW, high-voltage systems (e.g., BYD HVS, Huawei LUNA2000) can be a cost-effective option in terms of cabling costs.
