Sync Energy Flow All-in-One Home Energy System

The Sync Energy Flow All-in-One Home Energy Storage System is a flexible home energy management solution combining hybrid inverter technology and modular battery storage into a single, scalable unit. Designed for UK installations, it enables homeowners to store energy from solar generation or the grid and use it when needed most, helping to optimise energy use throughout the day and night.

Manufactured by Sync Energy, this system integrates inverter and battery functionality into a clean stacked format suitable for modern domestic properties. It can be installed as part of a new solar setup or retrofitted into an existing home energy system, offering long-term adaptability without unnecessary complexity.

Flexible All-in-One Home Energy Storage

This system is available in 3.6kW or 6kW inverter configurations and supports modular battery expansion starting from 5.12kWh. Additional battery modules can be added as energy demand grows, making it suitable for both smaller homes and higher-consumption households.

• All-in-one hybrid inverter and battery system
• 3.6kW and 6kW single-phase inverter options
• Modular battery storage starting from 5.12kWh
• Expandable storage for future energy needs
• Integrated fire suppression within battery modules
• IP65-rated enclosure for indoor or sheltered outdoor installation
• App-based monitoring and system control
• High-efficiency performance up to 97% CEC efficiency

The integrated hybrid inverter allows energy to be stored from solar panels or imported from the grid during lower-cost periods, then used during peak demand times. This flexibility makes the system suitable for homes with solar as well as properties preparing for future renewable upgrades.

Designed for UK Homes and Installers

The Sync Energy Flow range has been engineered for straightforward installation and long-term reliability. With wall-mounted inverter capability and floor-standing battery stack options, installers can adapt the layout to suit available space and property requirements.

The system includes integrated safety protections such as residual current detection, surge protection, anti-islanding protection and fire suppression modules. These features provide reassurance for both installers and homeowners looking for dependable home energy storage.

Smart Monitoring and Energy Control

Remote monitoring and control are available through the Sync Energy app, allowing users to track generation, storage and consumption in real time. Connectivity options include Wi-Fi, Ethernet and CAN/RS485 communications, making integration into modern smart home setups straightforward.

If you’re wondering whether this system suits a retrofit property or a new solar installation, it has been designed to support both. It can operate with solar panels, grid charging or a combination of both, giving installers flexibility when specifying systems for different homes.

Refer to technical specifications for full performance data, battery capacities and inverter options available within this range.

System Integration and Compatibility

The Sync Energy Flow All-in-One system is designed to sit at the centre of a modern home energy setup. By combining hybrid inverter capability with modular battery storage, it allows properties to store excess solar generation, import energy during lower-rate periods, and use stored power when demand is higher.

This makes the system suitable for properties installing solar panels today as well as homes planning phased upgrades over time. Additional battery modules can be added to increase storage capacity, while the hybrid inverter supports direct connection to PV arrays and grid supply.

• Compatible with solar PV systems
• Works with Sync Energy hybrid inverter technology
• Expandable using Sync Energy battery modules
• Suitable for time-of-use energy tariffs
• Pairs with home EV charging setups

Whether installed as part of a full renewable upgrade or as a standalone storage solution ready for future solar, the system provides flexibility without requiring major redesign later. This makes it particularly useful for installers planning systems that may expand over time.

System Sizes and Configurations

The all-in-one platform is available in multiple configurations combining inverter output and battery capacity. This allows installers to match storage and power output to the property’s energy profile.

• 3.6kW inverter with 1–3 battery modules
• 6kW inverter with 1–3 battery modules
• Battery capacity starting from 5.12kWh
• Expandable modular storage
• Single-phase UK supply compatibility

Each configuration is designed to deliver reliable daily cycling and consistent performance, with LiFePO4 battery chemistry supporting long service life and stable operation across a wide temperature range.

Dimensions and Weight

Dimensions and weights vary depending on battery stack height and configuration. Below are typical installation measurements for the system range.

• 979×621×245mm — 99.6kg
• 1288×621×245mm — 150.7kg
• 1597×621×245mm — 201.8kg

The inverter section can be wall-mounted while battery modules form a stacked floor-standing unit. This allows installers to adapt placement depending on space, ventilation and property layout.
