Product Description

The Sync Energy Flow All-In-One 3.6kW Hybrid Inverter with 2 Batteries is a sleek, integrated home energy storage system that combines power conversion, battery storage and smart control in one compact, stackable unit. Designed to help homeowners cut electricity costs, maximise self-consumption of solar power and maintain essential power during outages, it’s an ideal solution for modern energy management.

This configuration includes two 5.12kWh LiFePO₄ modular batteries for a total storage capacity of 10.24kWh (batteries offer 90% depth of discharge). The system is PV-ready, allowing solar PV to be added at any time, and the modular design makes it easy to expand capacity in the future without replacing the inverter.

For installers, the Flow system is engineered for fast setup and flexible mounting, with a spacious internal layout that keeps wiring straightforward. Homeowners benefit from intelligent optimisation through the Sync Energy app, giving real-time visibility of solar generation, grid usage and battery performance, with tools to track savings and optimise tariffs.
