Key Highlights of 5.12kWh Home Energy Storage Battery

Solyx BTA-C Series 5.12kWh LiFePO4 Battery is a high-performance energy storage device for residential and small commercial solar systems. It fits on-grid, off-grid and hybrid solar scenarios, delivering stable power backup, efficient solar energy storage and peak load shifting for daily and emergency power use.

It adopts authentic top-tier A+ grade LiFePO4 cells from Great Power and REPT BATTERO, world-renowned professional energy storage cell suppliers. These premium cells feature low internal resistance, consistent capacity and excellent thermal stability. They effectively prevent capacity attenuation and voltage fluctuation, eliminating thermal runaway risks and ensuring long-term stable battery performance compared with ordinary generic cells.

Thanks to premium cell quality, the battery delivers over 8000 cycles at 80% DOD with a 20-year design life. It far outperforms lead-acid and ordinary lithium batteries in service life and durability. It maintains high capacity retention after long cyclic use, requires no daily maintenance, and greatly reduces later replacement and maintenance costs for higher long-term cost performance.

The battery supports flexible capacity expansion. Single unit provides 5.12kWh capacity, and up to 9 units can be parallel connected to reach a max 45kWh system capacity. Users can freely expand the system according to actual power demands, suitable for both household and small commercial energy storage needs. Built-in intelligent parallel balance ensures even charge and discharge to protect the whole battery system.

Certified with UN38.3, MSDS, IEC62619 and UL1973, the product fully complies with global safety and transportation standards. With first-line brand cells, ultra-long cycle life and flexible expandable design, it is a safe, reliable and cost-effective energy storage solution for solar backup power and commercial energy storage projects.
