Sunpok Power Fortress: The 20.48kWh Core of Your Home Energy Independence

Imagine confidently powering your essential home comforts – lights, refrigeration, your connectivity hub – even when the grid falters. Sunpok's robust 51.2V 400Ah Lithium Iron Phosphate (LiFePO4) battery delivers a substantial 20.48kWh of reliable stored energy, forming the solid core of a more resilient, independent household.

​​Why the Sunpok Energy Fortress Empowers Your Home:​​

1. ​​Significant Capacity, Stable Foundation:​​ Experience the confidence that comes with 20.48kWh* of usable energy storage. This ample capacity reduces reliance on the grid and provides critical backup during outages, empowering you to sustain essential functions longer.
   ​**​(Usable capacity based on standard LiFePO4 depth of discharge, actual use dependent on system configuration and conditions).*

2. ​​Space-Conscious Strength:​​ Designed with practicality in mind, its modern vertical profile integrates smoothly into garages, utility rooms, or basements, maximizing valuable floor space while housing substantial power.

3. ​​Long-Term Value Engineered:​​ Utilizing inherently safer and long-lived LiFePO4 chemistry, the Sunpok battery is engineered for extended service life and stable performance across thousands of cycles, offering enduring value for your investment.

4. ​​Comprehensive Protection Built-In:​​ Engineered safety features include Battery Management System (BMS) monitoring for cell voltage, temperature, and current control. Basic environmental dust and water resistance is provided (IP21). Always prioritize safety: install on non-combustible surfaces away from flammable materials and potential hazards.

​​How It Anchors Your Energy Strategy:​​

• ​​Solar Energy Maximization:​​ Seamlessly pair with compatible solar inverters to capture surplus daytime solar generation. Store that clean energy efficiently and use it when you need it most – during peak evening hours or grid disruptions.
• ​​Essential Backup Power:​​ Be prepared. The Sunpok battery provides crucial, silent power backup for key circuits, ensuring lights stay on, food stays cold, and essential devices stay operational until grid power returns. ​​Professional integration is required to enable backup functionality.​​

​​Engineered for Practical Independence:​​

• ​​LiFePO4 Technology:​​ The foundation of inherent safety, thermal stability, and a lifespan far exceeding traditional lead-acid batteries.
• ​​Integrated BMS:​​ Continuously oversees performance, guarding against overcharge, deep discharge, overcurrent, and short circuits.
• ​​Vertical Design:​​ Optimizes space utilization for powerful home energy storage solutions.​​
