Description

Product Description

The SVOLT 5.43 kWh rack mount battery is engineered to deliver reliable, efficient energy storage for residential, commercial, and industrial applications. Built with A-Grade LiFePO₄ cells, this battery offers exceptional safety, stability, and a long cycle life. Its integrated Battery Management System (BMS) continuously monitors cell voltage, current, temperature, and state-of-charge to protect against over-charge, over-discharge, short circuits, and over-current conditions. The rack-mount design is space-efficient and suitable for structured battery racks in energy storage installations. The unit supports parallel expansion of up to 16 batteries to scale capacity for larger systems. With high round-trip efficiency and low self-discharge, this battery is effective for daily solar cycling, backup power, load shifting, and energy self-consumption applications.
