Deye Stacked Battery each 5.12 kWh, up to 12 modules, 20.48~61.44 kWh

The Deye Stacked Battery B0S-G is a modular solar battery system offering reliable energy storage for homes and businesses. Each Deye battery module provides 5.12 kWh of usable capacity using safe LiFePO₄ (LFP) cells. Modules are stackable batteries, letting you start with a smaller setup and expand as needed. You can combine up to 12 battery modules in one stack – scaling total storage from about 20.48 kWh to 61.44 kWh – to suit anything from residential solar backup to light commercial use. This flexible design makes it easy to right-size the battery bank for your project. 

Engineered as a hybrid battery solution, the Deye B0S-G works seamlessly with solar power systems and hybrid inverters. Its stackable module design means installation is simple: just stack modules in the dedicated cabinet. The system is fully scalable and can be adapted for various applications, whether you need a small home backup battery or a larger commercial battery storage setup. With advanced battery management and a robust build, this Deye battery system delivers both technical flexibility and long-term performance for savvy solar installers and end-users.

Deye Stacked Battery

The Deye Stacked Battery (B0S-G) system allows up to 12 battery modules to be stacked securely in a single cabinet. 

The Deye B0S-G stacked battery features a compact, stackable cabinet design built around standard 19-inch rack modules. Each module is a 51.2 V, 100 Ah battery module (5.12 kWh) that slots into the rack, connecting in series to create a high-voltage battery bank. The modules lock together with integrated connectors – no external cables needed between units – which makes the stacking method both safe and neat. A master control unit (high-voltage battery management box) sits at the top of the stack to manage the series-connected modules and provide a single interface to your inverter. 

In terms of capacity and physical design, the system is very scalable. A minimum of 4 modules (approx. 20.5 kWh) can be used for smaller installations, and up to 12 modules (61.44 kWh) can be stacked for large storage needs.

The entire assembly is enclosed in a sturdy cabinet with an IP65-rated enclosure, so it’s protected from dust and water – allowing indoor or outdoor installation. This stackable battery system is ideal for a wide range of use cases: from residential solar self-consumption and backup power, to small business energy storage, and even as part of larger commercial or industrial energy projects.

The plug-and-play modular design and natural cooling, fanless operation mean that installers can set it up quickly and it will run quietly and efficiently day-to-day.

Key Features of Deye Stacked Battery

• Convenient: Quick installation, standard of 19–inch embedded design module is comfortable for installation and maintenance.
• Safe and reliable: Cathode material is made from UFeP04 with safety performance and long cycle life. The module has less self-discharge, up to 6 months without charging it on shelf, no memory effect, excellent performance of shallow charge and discharge.
• Intelligent BMS: It has protection functions including over-discharge, over-charge, overcurrent and over-high or low temperature. The system can automatically manage charge and discharge state and balance current and voltage of each cell.
• Eco-friendly: The whole module Is non-toxic, non-polluting and environmentally friendly.
• Flexible configuration: Multiple battery modules can be in parallel for expanding capacity and power.Support USB upgrade, wifi upgrade (optional), remote upgrade (Compatible with Oeye inverter).
• Wide temperature: Working temperature range is from -20°C to 55°C, with excellent discharge performance and cycle life.

Main Benefits

• Flexible energy storage: Scale the battery size to suit any project’s needs. This modular system lets you tailor the storage capacity for a small residential setup, a medium-sized business, or a larger commercial facility.
• Cost-effective solution: The modular design reduces upfront investment. You can start with a few modules and expand later as your budget or energy requirements grow, rather than buying a huge battery all at once.
• Easy installation: Tool-free stacking and plug-and-play battery modules make installation quick and simple. There’s no complex wiring between modules – just stack them, connect the main cables, and you’re ready to go.
• Space-saving cabinet: The vertical stackable cabinet has a compact footprint, saving floor space. By building upward rather than outward, it fits more capacity in a smaller area, which is great for garages or equipment rooms with limited space.
• Seamless integration: Designed to work with Deye’s own hybrid inverters and other compatible systems, the battery integrates smoothly into smart energy setups. It communicates effectively with the inverter for charging, discharging, and backup power, creating a harmonious solar storage solution.
