Stacked lithium battery 15kwh-30kwh

Our stacked lithium battery series offers a modular and expandable energy storage solution designed for residential and light commercial applications. With flexible configuration from 3 to 6 modules, system capacity scales from 15.36kWh to 30.72kWh at voltages from 153.6V to 307.2V—perfect for growing energy needs.

Each module integrates a 100A smart BMS with central BMS coordination, ensuring seamless communication and compatibility with leading inverters via RS485 and CAN protocols. Built with reliable LiFePO₄ cells, this stackable system delivers 6000 cycles at 90% DOD (0.2C, 25°C), providing long-lasting performance and peace of mind.

The space-efficient stacked design simplifies installation and expansion, while comprehensive protections (overcharge, over-discharge, overcurrent, short circuit, over temperature) ensure safe, reliable operation across a wide working temperature range (-10°C to +50°C). Whether for new installations or system upgrades, this scalable solution adapts to your energy requirements.

🏡 Residential Solar Storage

Ideal for homes with solar PV systems, storing excess energy generated during the day for use at night or during cloudy periods. Scalable capacity from 15.36kWh to 30.72kWh accommodates small to large households with varying energy consumption patterns.

⚡ Backup Power for Homes

Provide reliable backup power during grid outages to keep essential appliances running—lights, refrigerators, Wi-Fi routers, medical devices, and security systems. High-voltage design integrates seamlessly with home electrical systems for automatic backup operation.

💰 Time-of-Use Optimization

Reduce electricity bills by storing energy during low-rate periods (off-peak) and discharging when rates peak. The scalable capacity allows homeowners to maximize savings based on their usage patterns and local utility rate structures.

🌲 Off-Grid Living

Serve as the primary power source for off-grid homes, cabins, or remote properties requiring substantial daily energy. Multiple modules can be stacked to provide complete energy independence year-round, paired with solar or other renewable sources.

📈 Growing Energy Needs

Perfect for households planning to expand their energy consumption over time—add an EV charger, heat pump, electric water heater, or additional appliances without replacing the entire battery system. Start with 3 modules and expand to 6 as needs grow.

🏢 Small Commercial Applications

Suitable for small businesses, retail stores, restaurants, or offices requiring reliable backup power and energy cost management. The professional stacked design presents a clean, organized appearance suitable for customer-facing environments.

🏗️ New Home Construction

Ideal for new homes designed with future energy needs in mind. Install the base configuration (3 modules) now and easily add modules later as budget or requirements grow, without construction disruptions.

🔧 Solar System Upgrades

Upgrade existing solar installations by adding battery storage. The modular design allows right-sizing the battery to match existing solar array capacity, maximizing self-consumption and energy independence.

🏘️ Multi-Family Dwellings

Support common area loads in apartment buildings, condominiums, or townhouses—lighting, elevators, security systems, intercoms, and shared laundry facilities—with reliable backup power.

⚙️ Demand Charge Management

For properties with demand-based utility rates, the stacked battery system can reduce peak demand charges by supplementing grid power during high-consumption periods, lowering monthly operating costs.
