Description
Illustration: The Deye AI-W5.1-B stacked battery system (base, modules, and top PDU) fully assembled. The Deye Stacked Battery Base PDU (Model AI-W5.1-B) is a modular solar battery system designed for flexibility and performance. Each battery module provides 4.6 kWh of usable capacity, and you can stack between 1 to 6 modules to achieve a total of 5.12–30.72 kWh storage per stack
This Deye battery system is engineered to integrate seamlessly with Deye’s hybrid solar inverters, creating a complete hybrid battery backup solution. The battery modules are housed in an integrated cabinet that includes a bottom base plate for stability and a top-mounted Power Distribution Unit (PDU) for system control and inverter connections. Assembly is tool-free – simply stack the modules on the base and secure the top PDU, with no complex cabling between modules.
The result is a tidy, space-saving tower that can be installed indoors or outdoors, thanks to its durable IP65-rated enclosure and passive cooling design (no noisy fans needed). In short, the Deye stacked battery delivers a commercial battery grade build with user-friendly installation, making it an excellent choice for anyone looking to add scalable energy storage to their solar setup.
Deye Stacked Battery AI-W5.1-B
The Deye AI-W5.1-B stacked battery system is a cutting-edge energy storage solution built around 5.12 kWh LFP battery modules. Each module features an independent Battery Management System (BMS) for safety and longevity, and up to six modules can be stacked in a single tower for a total of 30.72 kWh of storage capacity. The modules connect in series within the stack, and multiple stacks can also be paralleled for even higher capacity needs (e.g. for larger commercial installations.

Ningbo Deye Inverter Technology Co., Ltd
Ningbo Deye Inverter Technology Co., Ltd is a leading high-tech manufacturer specializing in solar inverters and energy storage solutions. Founded in 2007, Deye has grown into a globally recognized solar inverter brand, offering a wide range of inverter products (on-grid, hybrid, and micro inverters) that are often regarded among the best solar inverters in Australia.
Deye’s commitment to quality and innovation has made its inverters and energy storage systems popular for residential and commercial solar projects alike, cementing the company’s reputation as a reliable industry leader in renewable energy technology.
The Deye stacked battery system is very flexible. The minimum configuration is 5.12 kWh (a single module), and it can be expanded up to 30.72 kWh with six modules in one stack. This capacity range covers typical household backup needs and can scale up for larger power requirements.
(For even greater capacity, multiple 30.72 kWh stacks can be connected in parallel, though one stack is usually sufficient for most home and SME applications)
Yes – the system is fully modular and designed to be easily expandable. You can begin with just one or a few modules and add additional 5.12 kWh battery modules later (up to a total of 6 modules per stack) as your energy storage needs grow. The plug-and-play stacking design means you won’t need to rewire the whole system or replace the inverter; simply stack the new module onto the base, connect it under the PDU, and the BMS will automatically integrate the new module into the system.
Absolutely. The Deye AI-W5.1-B stacked battery is specifically engineered to work with Deye hybrid solar inverters for seamless integration. The included DC power cables and communication cable are made to connect directly to a Deye hybrid inverter’s battery input ports.
Once connected, the inverter will communicate with the battery’s BMS to manage charging, discharging, and provide accurate state-of-charge readings. This tight integration ensures optimal performance and safety.
(It’s always recommended to check that your Deye inverter’s firmware is up-to-date for best compatibility with the battery)
Yes. The Deye stacked battery system is housed in a weather-resistant IP65-rated cabinet, which means it’s dust-tight and protected against water jets from any direction. In practical terms, it can be safely installed outdoors on a wall or ground mount without worrying about rain or debris.
Additionally, the battery is designed to operate in a broad temperature range (approximately -20 °C to 55 °C) with no active cooling, so it can handle both cold winters and hot summers in Australia. For outdoor installs, just ensure the cabinet is placed on a stable, level surface (or securely wall-mounted with the proper brackets) and not in direct, harsh sunlight if possible (to minimize thermal stress).
The Deye stackable battery is much easier to install than many traditional battery banks due to its all-in-one modular design.
Each module is a manageable size, so you’re not lifting one gigantic heavy battery all at once. The modules self-connect when stacked, eliminating the need to wire modules together with jumper cables – this reduces installation error and time. The included base and PDU align everything, and there’s no need for additional racking or enclosures since the system creates its own cabinet as you build it. In short, you set the base, stack the modules, bolt on the top PDU, and connect the single set of cables to your inverter.
This streamlined, tool-free assembly saves on labor and makes it feasible for an installer (or technically savvy homeowner) to set up quickly. It’s a plug-and-play solution compared to bolt-together battery racks or wall-mounted units that might require separate mounting brackets for each module.
