About This Product

The Sungrow 6.4kW High Voltage LFP Battery is a modular high-voltage lithium iron phosphate (LFP) battery designed for use with compatible Sungrow hybrid inverters. It forms part of Sungrow’s high-voltage residential energy storage system and is built to deliver stable performance, long cycle life and improved safety compared to older lithium chemistries.

This battery module integrates with Sungrow’s high-voltage battery management system (BMS) and allows multiple modules to be stacked to increase total system capacity. The LFP chemistry offers strong thermal stability and is well suited to Australian conditions, including high ambient temperatures when installed correctly.

The unit is intended for grid-connected solar systems with battery backup capability, supporting self-consumption, time-of-use optimisation and backup supply when paired with an appropriate Sungrow hybrid inverter.

Who This Product Suits

• Homeowners installing a new Sungrow hybrid solar and battery system.
• Existing Sungrow hybrid inverter owners expanding their storage capacity.
• Households looking to increase solar self-consumption and reduce grid reliance.
• Homes on time-of-use tariffs wanting to store solar energy for evening use.
• Installations requiring a high-voltage battery architecture rather than low-voltage systems.

This battery must be paired with compatible Sungrow high-voltage hybrid inverters and installed by a licensed electrician.

Specifications Explained

• Nominal Capacity: Approximately 6.4 kWh per module, allowing scalable system design.
• Battery Chemistry: Lithium Iron Phosphate (LFP) for improved thermal stability and long service life.
• High-Voltage Design: Operates as part of a high-voltage battery stack for improved inverter efficiency and reduced current losses.
