Product Description

The Sync Energy Flow All-In-One 3.6kW Hybrid Inverter with 3 Batteries is a high-capacity, integrated energy storage system designed for homes with greater energy demands. By combining a hybrid inverter, modular battery storage and smart control into one sleek, stackable unit, it enables homeowners to maximise solar self-consumption, reduce energy bills and maintain power during outages.

This configuration is supplied with three 5.12kWh LiFePO₄ batteries, providing a total usable storage capacity of 15.36kWh (90% depth of discharge). The system is fully PV-ready, allowing solar panels to be added at any time, and the modular design makes future battery expansion simple without replacing the inverter.

Intelligent energy management is delivered via the Sync Energy app, offering real-time monitoring of solar generation, grid usage and battery performance. With integrated safety features, outdoor-rated protection and silent operation, the Flow system is a future-proof solution for modern, energy-conscious homes.
