Sungrow SBR064 6.4kWh High Voltage Battery System Kit
The Sungrow SBR064 HV Battery Combo Kit is a compact, high-voltage 6.4kWh lithium iron phosphate battery system designed for residential energy storage applications.
The system consists of two 3.2kWh stackable battery modules and one empty/dummy module, providing a reliable and flexible battery storage solution for compatible Sungrow hybrid inverter systems. It is ideal for increasing solar self-consumption and supporting backup power applications when paired with a suitable inverter.
With its modular, plug-and-play design, the SBR064 is quick to install and can be expanded over time to meet changing energy storage requirements. The SBR storage system supports 2 to 8 battery modules per stack/tower, allowing expansion from 6.4kWh up to 25.6kWh.
