15kWh Stacked LiFePO4 Battery 51.2V 300Ah Home Storage

Product Overview

The SUNPOK 51.2V 300Ah Stacked Series is engineered for flexibility, safety, and aesthetic integration. The standout feature of this 15kWh single unit is its ultimate scalability. Unlike wall-mounted batteries that require a load-bearing wall, professional structural assessment, and leave limited room for future expansion, this floor-standing system requires only approximately 0.3–0.5 square meters of floor space and can be freely repositioned. When your energy demands increase — whether you add an EV charger, a heat pump, or an extension to your home — you don't need to replace the entire system. You simply stack another 15kWh module on top. The sleek white casing blends perfectly with contemporary home interiors, while the system communicates flawlessly with major inverter brands via RS485, CANBUS, and RS232 protocols.

Key Product Advantages

Application Scenarios

◼︎ Growing Families & Future-Proofing

Perfect for families planning home renovations or expecting increased energy needs. Start with 15kWh now, and effortlessly stack additional modules later when you add a home office, EV, or new appliances. You never have to worry about your battery becoming obsolete.

◼︎ Residential Solar Self-Consumption

Store excess solar energy generated during the day for use at night or during peak utility rate periods. By storing your daytime solar production and discharging during high-tariff hours, you can dramatically reduce monthly electricity bills and achieve faster payback on your solar investment.

◼︎ Whole-Home Backup Power

With 10,240W of continuous output power, this single 15kWh system provides robust whole-home backup during grid outages. The capacity comfortably covers essential loads (refrigerator, lighting, Wi-Fi, medical devices) for extended periods, and can handle heavier appliances like air conditioning and well pumps simultaneously.

◼︎ Off-Grid Living

Provide reliable, continuous power for remote cabins, tiny homes, and off-grid properties where grid access is unavailable or unreliable. The 51.2V 300Ah capacity allows you to size the system precisely to your off-grid energy needs, and expand it easily as your off-grid lifestyle evolves.

◼︎ EV Charging Support

With 200A max charging and discharging current, the system can support Level 2 home EV charging directly from stored solar energy — reducing your transportation energy costs and carbon footprint.
