Sungrow SBR128 12.8kWh Solar Battery Storage Performance and Capacity

The Sungrow SBR128 12.8kWh solar battery storage consists of four series-connected 3.2 kWh modules providing 12.8 kWh of fully usable energy at 100 percent depth of discharge. Continuous charge and discharge current is rated at 30 A with a 10-second peak of 42 A, delivering a rated DC power of 7.68 kW and maximum charge or discharge power of approximately 8.76 kW for responsive household support. Nominal voltage is 256 V with an operating range of approximately 200 to 292 V, optimised for efficient high-voltage DC coupling with compatible hybrid inverters.

Round-trip efficiency is among the highest in its class, supporting maximised solar self-consumption with minimal energy loss during daily cycling. The complete tower measures 625 x 675 x 330 mm and weighs 147 kg, remaining practical for floor-standing indoor or covered outdoor installation. The modular design allows expansion within the same tower up to eight modules for 25.6 kWh, while up to four towers can be paralleled for larger total capacity when required.

Cell technology is lithium iron phosphate prismatic cells, cobalt-free and selected for thermal stability and long cycle life. Operating temperature supports charge from 0 to 50 degrees Celsius and discharge from minus 20 or minus 30 to 50 degrees Celsius depending on exact configuration, ensuring reliable performance across Australian climate conditions.

Sungrow SBR128 12.8kWh Solar Battery Storage Compatibility Safety and Durability

Sungrow SBR128 12.8kWh solar battery storage Inverter compatibility centres on Sungrow hybrid inverters such as the SH series, with CAN communication enabling seamless monitoring and control. The system supports on-grid, hybrid and backup applications when paired with a suitable hybrid inverter. Multi-stage protection includes over and under voltage, over current, over and under temperature and an integrated DC breaker for enhanced system safety.

Enclosure protection is rated IP55, providing effective weather-seal protection against dust and water for indoor or covered outdoor locations. The robust modular construction is engineered for durability under temperature cycling and normal mechanical stress. Certifications include CE, CEC, IEC 62619, IEC 62040, UN38.3 and VDE 2510-50, confirming compliance with high international safety and transport standards.

Pre-shipment inspection checks verify module capacity, voltage balance, communication integrity and physical condition before dispatch. Every system is factory-tested and batch-certified so customers receive verified performance data. The stable LiFePO4 chemistry combined with multi-stage protection and the protective enclosure minimises weather-related degradation, supporting the full ten-year product warranty under normal operating conditions.
