51.2V LiFePO4 Home Energy Storage

The 51.2V LiFePO4 Home Energy Storage system (5kWh/100Ah capacity) is a high-performance modular powerwall tailored for modern residential solar setups—whether you’re aiming to cut grid reliance, save on peak-hour electricity costs, or secure backup power during outages. Its innovative stackable design supports seamless capacity expansion (from 5kWh up to 20kWh with 2-6 battery units), making it far more flexible than fixed-size alternatives while occupying minimal space in basements, garages, or utility closets.

Crafted with premium cobalt-free LiFePO4 cells (a safer, longer-lasting alternative to traditional lithium-ion), this 51.2V 100Ah LiFePO4 Home Energy Storage Battery boasts an industry-leading 6000+ deep charge-discharge cycles (translating to a 10+ year operational lifespan) and 98% charging efficiency. This means it can store excess solar energy during the day and release it when electricity rates peak, slashing monthly utility bills by up to 30% for average households. Equipped with a multi-layer intelligent BMS (Battery Management System), it provides real-time protection against overcharge, over-discharge, short circuits, and thermal runaway—ensuring stable, safe operation even in extreme temperatures (-20°C to 60°C) and diverse climate conditions.

Fully compatible with all mainstream solar inverters and charge controllers (including Victron, Solis, and Goodwe), this 5kWh 51.2V LiFePO4 Solar Energy Storage System comes with MSDS, UN38.3, and CE certifications, meeting global safety and quality standards. Its IP21 dust/water resistance (with optional IP55-rated cabinet for outdoor use) and robust screw-fastened internal assembly further enhance durability, while the plug-and-play installation design lets homeowners set it up with minimal technical expertise. Whether powering essential appliances, home offices, or entire living spaces, this system balances scalability, efficiency, and safety—making it the ideal eco-friendly energy storage solution for forward-thinking households.
