Product Specification

Sunpok 51.2V 400Ah Home Battery: Substantial Energy Resilience Where You Need It​​

​​Amplify Your Energy Reserves.​​ Sunpok’s 51.2V 400Ah Lithium Iron Phosphate (LiFePO4) battery delivers 20.48kWh of usable power, engineered to extend backup duration for essential home systems. Maintain refrigeration, lighting, and critical electronics through prolonged grid disruptions – ensuring continuity and confidence even during extended outages.

​​Vertical Footprint Advantage.​​ Optimize valuable installation space with Sunpok’s tower-design battery. Install it in corners, utility spaces, or alongside existing equipment. This vertical architecture offers high energy density per square foot, freeing floor space without compromising capacity.

​​Enduring LiFePO4 Reliability.​​ At its core lies inherently stable Lithium Iron Phosphate chemistry. This foundational choice ensures safety, minimizes degradation, and supports thousands of deep discharge cycles for sustained reliability. Your investment is engineered for years of predictable performance.

​​Standard Compatibility.​​ Designed for simple connection to common 51.2V solar inverters and residential energy systems. Its IP21 indoor protection rating (shielding against vertical water drips and incidental dust contact) makes it suitable for garages, basements, or utility rooms in dry environments.

​​Purpose-Built Energy Density.​​ This battery focuses purely on core performance: massive energy storage (400Ah at 51.2V) in an intentionally compact vertical profile. For homeowners prioritizing resilient capacity and spatial efficiency, Sunpok delivers robust power infrastructure.
