20KWH Home Energy Storage Battery 51.2V 400AH LiFePo4 Battery 48V 20kw Lithium Battery with Wheels

Engineer Energy Resilience: Sunpok 51.2V 400Ah LFP Home Storage Solution​​

Optimize your home's power infrastructure with the ​​Sunpok 51.2V 400Ah Lithium Iron Phosphate Battery​​. Designed for extended backup durations and consistent performance, this vertical stationary battery delivers a substantial ​​20.48kWh energy reserve​​, enabling greater self-consumption of renewable energy or sustained operation of critical household systems.

​​High-Energy Density Meets Practical Design​​

Featuring space-efficient LiFePO4 (LFP) technology, this vertical battery offers significant capacity within a compact footprint (IP21 rating). The 51.2V nominal voltage optimizes compatibility with a wide range of common residential inverters, simplifying system integration for substantial power delivery.

​​Core Advantages: Efficiency and Cycle Life​​

• ​​Extended Daily Performance:​​ High energy retention minimizes losses between charge/discharge cycles.

• ​​Robust Longevity:​​ Stable LFP chemistry, governed by a protective BMS (over-voltage, under-voltage, short-circuit, over-temperature), supports sustained performance over numerous deep-cycle operations.

• ​​Thermal Stability:​​ LFP’s inherent thermal resilience contributes to operational safety in residential environments.

​​Optimized Form Factor for Space-Constrained Installations​​

The self-contained vertical structure provides inherent stability and minimizes required floor area. This design prioritizes functional integration into utility rooms, garages, or dedicated storage spaces without complex mounting requirements.

​​Purpose-Built for Capacity-Driven Scenarios​​

Ideal for applications demanding extended runtime:

• Supporting higher-power appliances during outages

• Maximizing solar self-consumption throughout the day and night

• Providing core power stability in hybrid energy systems

• Scaling storage capacity in high-demand households
