Product Description

The Sync Energy Flow All-In-One 6kW Hybrid Inverter with 2 Batteries is a powerful, integrated home energy storage system designed for properties with higher electricity usage. Combining a high-output hybrid inverter, modular battery storage and smart control in one sleek, stackable unit, it helps homeowners reduce bills, store solar power effectively and stay powered during outages.

Supplied with two 5.12kWh LiFePO₄ batteries, this configuration delivers a total storage capacity of 10.24kWh (with 90% depth of discharge). The system is fully PV-ready, so solar PV can be added at any time, and the modular design makes future expansion straightforward without needing to replace the inverter.

Remote monitoring and optimisation are handled through the Sync Energy app, providing real-time visibility of solar generation, grid usage and battery performance. With integrated safety features, outdoor-rated protection and silent operation, the Flow system offers a future-ready solution for energy-conscious homes.
