Deye 5.12kWh Low Voltage (LV) Lithium‑Ion LiFePO₄ Battery – Stackable Floor Mount (AI‑W5.1)
The Deye 5.12kWh Low Voltage (LV) Lithium‑Ion LiFePO₄ Battery (AI‑W5.1) is a high‑performance energy storage solution designed for residential and light commercial solar systems. Utilising advanced Lithium Iron Phosphate (LiFePO₄) cells, this battery delivers reliable power, exceptional safety, and long cycle life — making it ideal for South African homes and small businesses seeking dependable energy storage for load‑shedding backup or daily solar self‑consumption.
With a usable capacity of 5.12kWh, the AI‑W5.1 provides ample stored energy for vital loads such as lighting, refrigeration, home electronics, security systems, and more. Its 51.2V low‑voltage architecture ensures seamless compatibility with a wide range of hybrid and off‑grid inverters, including popular brands like Deye and Sunsynk, as well as other compatible low‑voltage systems.
Designed for flexibility and ease of installation, the Deye 5.12kWh battery features a stackable floor mount design, allowing multiple units to be connected in parallel to expand storage capacity as your energy requirements grow. This modular setup makes it an excellent choice for homeowners looking to scale their system over time without major equipment replacements.
The integrated smart Battery Management System (BMS) continuously monitors the battery’s state of charge, voltage, current, and temperature to protect against over‑charging, deep discharging, overheating, and short circuits. The result is a safer, more efficient energy storage solution with enhanced longevity and consistent performance under frequent cycling.
Compact, robust, and designed for practical installation, the AI‑W5.1 fits neatly into utility rooms, garages, or dedicated battery banks where floor space optimisation is important. Its high round‑trip efficiency ensures that more of the solar energy you generate is stored and available for use, helping to reduce reliance on the grid and lower electricity costs over time.
Whether you’re building a new solar storage system or expanding an existing one, the Deye 5.12kWh LV LiFePO₄ Battery delivers a powerful, scalable, and future‑ready storage solution that supports sustainable energy management in both residential and commercial settings.
