Product Description

The Sync Energy Flow All-In-One 6kW Hybrid Inverter with 3 Batteries is a high-capacity, fully integrated energy storage system designed for homes with significant electricity demand. Combining a powerful hybrid inverter, modular battery storage and intelligent control into a single stackable unit, it enables maximum use of solar generation while reducing reliance on the grid.

Supplied with three 5.12kWh LiFePO₄ batteries, this configuration delivers a total storage capacity of 15.36kWh with a 90% depth of discharge. The system is PV-ready, allowing solar PV to be added at any time, and the modular design ensures future battery expansion without replacing the inverter.

Smart monitoring and optimisation are handled through the Sync Energy app, giving real-time insight into solar generation, battery usage and grid consumption. With advanced safety features, outdoor-rated protection and silent operation, the Flow system provides a future-proof solution for modern energy management.
