Product Description

The Sync Energy Flow 6kW Single Phase Hybrid Inverter is a high-performance, future-ready solution designed for homes with greater energy demand. Ideal for solar PV, battery storage and smart energy management, it allows homeowners to maximise self-consumption, optimise off-peak tariffs and integrate EV charging with ease.

The inverter can be wall mounted or stacked within the Flow system, offering flexible installation options. With plug-and-play compatibility for Sync Energy 5.12kWh LiFePO₄ battery modules, storage capacity can be expanded up to 35.84kWh without replacing the inverter, ensuring long-term scalability.

Built-in safety features include integrated AC and DC surge protection, PV isolation and onboard protective devices, removing the need for additional external components. Supporting up to 150% PV oversupply and delivering 97% average efficiency, the inverter is engineered to capture more solar energy and convert it efficiently.

Full system control is provided via the Sync Energy app, enabling real-time monitoring of solar generation, grid import/export and battery performance, alongside tariff-based insights for smarter energy decisions.
