Product Description

The Sync Energy Flow 3.6kW Single Phase Hybrid Inverter is a smart, future-ready solution for modern homes looking to maximise solar generation, improve self-consumption and take control of energy costs. Whether you’re adding PV now or planning for battery storage later, this hybrid inverter provides a flexible platform that adapts as energy needs evolve.

Designed for simple installation, the unit can be stacked within a Flow system or wall mounted, with plug-and-play connectivity for Sync Energy battery modules. Start with a 3.6kW inverter and expand storage using 5.12kWh LiFePO₄ batteries up to a total of 35.84kWh, without needing to replace core equipment.

For safety and compliance, the inverter includes integrated AC and DC surge protection, along with PV isolation and built-in protective devices to reduce the need for additional components. With 150% PV oversupply capability and 97% average efficiency, it’s engineered to help you harvest more energy and make better use of every watt generated.

Control and optimisation is handled through the Sync Energy app, giving real-time visibility of solar, grid and battery usage, plus tools such as tariff-based insights to support smarter energy decisions.
