With scalable stacking up to ~30.72 kWh, IP65 outdoor/indoor rating, a wide operating temperature range (-20 °C to +55 °C) and a 10-year warranty, it delivers reliable, safe backup power and smart storage control. Ideal for South African homes preparing for load-shedding and solar self-consumption.
The Deye AI-W5.1-B LFP Lithium-Ion Battery is a premium modular energy storage system built for flexibility, safety, and long service life. Each module delivers a nominal capacity of 5.12 kWh, and you can stack the system up to 30.72 kWh. This means you can easily match your energy needs and expand the system later when required.
The battery uses LiFePO₄ (LFP) cells, which are cobalt-free and designed for high safety and long-term durability. It delivers over 6000 cycles at 70% end-of-life capacity, so you get reliable performance for many years.
In addition, the system performs well in tough conditions. It operates in temperatures from -20 °C to +55 °C, uses natural cooling, and comes with an IP65 rating, which makes it suitable for both indoor and outdoor installation. A built-in circuit breaker adds extra safety, while the 2.5 kW rated DC power allows smooth integration with hybrid or battery-ready solar systems.
Installation stays simple thanks to the stackable flat design and auto-networking feature. You can also monitor the system remotely, which makes it easy to track performance and energy use.
Overall, the Deye AI-W5.1-B battery system helps you reduce reliance on the grid, manage rising electricity costs, and keep your home or business powered during outages.
