Sync Energy Flow Battery Module 5.12kWh

The Sync Energy Flow 5.12kWh Battery Module is a modular lithium battery designed to integrate with Sync Energy hybrid inverters and all-in-one home energy systems. Built using LiFePO4 battery technology, it provides dependable daily cycling, scalable capacity and long service life for modern UK residential energy setups.

This battery module forms the core storage component within the Sync Energy Flow platform, allowing installers to configure systems that match a property’s energy demand. Starting with a single module and expanding over time, the system can grow alongside the homeowner’s usage, making it suitable for both new installations and retrofit upgrades.

Modular Battery Storage for Home Energy Systems

Each module provides 5.12kWh of usable storage and can be stacked with additional units to increase overall capacity. This flexibility allows installers to design systems based on real household consumption rather than oversizing from the outset.

• 5.12kWh modular battery storage
• LiFePO4 lithium battery chemistry
• Stackable design for expandable capacity
• Compatible with Sync Energy Flow hybrid inverter
• Integrated heating support for low temperatures
• Designed for daily cycling use
• Suitable for solar and grid charging

The LiFePO4 battery chemistry supports stable operation and long cycle life, making it a dependable option for homes storing solar generation or off-peak electricity. With a depth of discharge of up to 90% and a long cycle rating, it is designed for regular daily use rather than occasional backup.

Designed for UK Installations

The Sync Energy Flow battery module has been engineered for domestic UK installations and integrates directly into the Sync Energy system stack. Its compact footprint and stackable format allow it to be installed neatly in garages, utility spaces or plant rooms without requiring complex mounting structures.

Integrated safety features include battery protection systems, internal heating packs and secure inter-module connections. These help maintain performance across a wide operating temperature range and provide reassurance for installers specifying long-term home energy storage.

Expandable Storage Capacity

If you’re wondering whether you need maximum storage from day one, this modular design allows systems to start with a single battery and expand later. Additional modules can be added as energy usage increases, making it easier to scale systems over time.

Refer to the full system specifications for supported stack sizes and compatible inverter configurations.

System Integration and Compatibility

The Sync Energy Flow Battery Module is designed to work exclusively with the Sync Energy Flow hybrid inverter and all-in-one home energy systems. When installed as part of a complete setup, it allows energy to be stored from solar generation or imported from the grid and used later when required.

This flexibility makes it suitable for a wide range of residential applications. Homes can install battery storage alongside solar panels or use it to store lower-cost grid electricity for use during higher-demand periods. Additional battery modules can be added to increase total system capacity without replacing the existing setup.

• Compatible with Sync Energy Flow hybrid inverter
• Works within Sync Energy all-in-one systems
• Expandable battery storage platform
• Suitable for solar charging or grid charging
• Supports time-of-use energy tariffs
• Integrates with home EV charging setups

Because the module is designed to operate within the Sync Energy ecosystem, it ensures consistent communication, safe operation and reliable performance across the full system.

Performance and Technical Details

The battery uses LiFePO4 cells to deliver stable voltage, long cycle life and dependable performance across a wide range of operating conditions. Its design supports daily charging and discharging, making it suitable for homes actively managing energy consumption.

• Capacity: 5.12kWh
• Battery chemistry: LiFePO4
• Nominal voltage: 51.2V
• Depth of discharge: up to 90%
• Cycle life: up to 6000 cycles
• Expandable stack system

These specifications make the module suitable for use as part of both small and larger domestic energy storage systems.

Dimensions and Weight

Exact dimensions will depend on the number of modules stacked within the system. Each module is designed to form part of a floor-standing battery stack that connects directly to the inverter above.

• Stackable modular design
• Floor-standing installation
• Integrated carrying handles
• Secure interlocking connections

Installers can increase total system height by adding additional modules while maintaining a consistent footprint.
