Description

Product Description

The BOS-A 7.68kWh battery module is engineered to provide safe, efficient, and long-lasting energy storage for hybrid and off-grid solar systems. Built with advanced LiFePO₄ cell technology, it delivers enhanced thermal stability, deep discharge capability, and extended service life.

The modular design allows multiple units to be connected in parallel for increased storage capacity, making it suitable for both small residential installations and larger commercial energy systems. An integrated Battery Management System (BMS) ensures protection against overcharge, over-discharge, overcurrent, and temperature fluctuations.

The BOS-A 7.68kWh is ideal for load shifting, backup power, self-consumption optimization, and energy cost reduction in areas with unstable grid supply.
