Description

Product Description

The Sungrow 19.2 kWh battery package is part of Sungrow’s high-voltage SBR battery range, engineered to provide reliable energy storage, long cycle life, and enhanced safety. Built with LiFePO₄ cells and an intelligent Battery Management System (BMS), the system continuously monitors cell voltage, current, and temperature to maintain balance and protect against over-charge, over-discharge, over-current, temperature extremes, and short circuits.

The modular design consists of multiple stackable battery modules, allowing simple capacity expansion as energy needs grow. When paired with a compatible Sungrow hybrid inverter, the battery supports solar self-consumption, load shifting, and uninterrupted backup power during grid outages. The robust enclosure supports indoor or sheltered outdoor installation and is backed by Sungrow’s warranty and certification standards.
