Description

Product Description

The Sungrow 12.8 kWh battery package is part of the Sungrow SBR high-voltage battery series, engineered for long-term durability, safety, and scalability. The system uses premium LiFePO₄ prismatic cells and includes all necessary accessories for installation. Its modular design allows expansion through additional units or extra modules over time, supporting future energy needs. The battery supports continuous charging and discharging at up to 30 A, offers nearly 100 percent usable capacity, and features advanced multi-stage protections for over-voltage, over-current, and temperature excursions. With an IP55 protection rating and a 10-year warranty, this battery package is suitable for indoor or sheltered outdoor installation and integrates seamlessly with hybrid inverters for solar self-consumption, load shifting, and backup power applications.
