Flexible Storage with Built-In Scalability
With a modular design, the Smile G3 allows you to start small and expand as your energy needs grow. Storage capacities range from 5.04kWh up to 30.24kWh, making it ideal for everything from modest homes to larger properties with higher energy demands. The system comes with a built-in hybrid inverter, enabling seamless integration with both new and existing solar PV setups without the need for additional components.
Smart Monitoring and Intelligent Energy Management
The Smile G3 offers full visibility and control through the AlphaCloud platform and mobile app. Monitor your energy generation, storage, and usage in real time, and optimise your system to charge during off-peak times or export energy when rates are high. Intelligent management helps you reduce electricity costs and maximise your return on investment, all from the palm of your hand.
Reliable Backup for Peace of Mind
In the event of a power outage, the Smile G3 automatically provides uninterrupted backup power to your critical circuits, keeping your essential devices running smoothly. Engineered for durability and longevity, the system uses advanced lithium iron phosphate (LFP) battery technology, ensuring high performance, safety, and a longer lifespan. Backed by AlphaESS’s strong warranty and global reputation, the Smile G3 is a future-proof choice for smart energy living.
