Alpha ESS batteries are expandable from 10.1 kWh – 60.6 kWh
Alpha Smile 5 is a high-performance, all-in-one hybrid energy storage system designed to deliver reliable power, smart energy management, and long-term savings.
Our Alpha SMILE 5 10.1 system offered at the Solar Battery Group provides 10.1 kWh of storage per unit. It can expand with plug-in-and-play units, up to 60.6 kWh – a total of 6 modules. It's the perfect larger battery storage system for homes and small businesses wanting real energy independence.
Unlike many battery systems, the AlphaESS Smile5 10.1 kWh Battery also includes a built-in hybrid inverter, meaning there's no need for an external inverter.
This saves costs, simplifies installation, and helps ensure seamless compatibility with any brand of solar panels and most Virtual Power Plants (VPPs) in Australia. Allowing you to unlock even more financial incentives, if you choose to.

The Smile 5's integrated hybrid inverter delivers 5 kW of continuous output, giving your home significantly more flexibility than smaller 3 kW systems. This higher capacity allows you to power a wide range of daily-use appliances at the same time without stressing your system:
Essential loads like: fridges, lights, TVs, computers, fans, and multiple kitchen or laundry devices at once.
Medium to high loads like: microwaves, kettles, washing machines, dishwashers, and vacuums.
Short bursts of high power spike users like: fridges, heat pump hot water units, and power tools.
This means you can run more appliances simultaneously, manage daily power spikes with confidence, and even support light to medium air-conditioning.
The Smile 5 battery is designed to charge quickly during the day and deliver power smoothly when you need it. Its 100-amp charge and discharge capability allows it to absorb solar energy at a fast rate, which means it can refill more of its capacity during sunny hours. The system also has a 96% Depth of Discharge (DoD). In simple terms, this means you can use almost the entire 10.1 kWh of stored energy in each cycle, instead of losing a portion of it like many older battery models. The result is more usable power for your home and better overall value from your battery investment.
The Alpha Smile 5 includes UPS-grade backup capability. During a blackout, the Smile 5 automatically supplies power to the essential circuits connected to its backup port, helping keep critical appliances running safely and without interruption. The system makes this switch to battery power in milliseconds.
This makes it ideal for:
Please note: Activating blackout protection is an opt-in feature with added cost to cover additional labour, such as modifications to your building switchboard.
The Smile 5 is covered by:
Alpha ESS guarantees that the battery will keep at least 80% of its original usable capacity for up to 10 years (120 months).*
*Additional terms and conditions apply.
Despite its impressive capacity, the system is compact and installer-friendly. With a tidy wall-mounted design, it fits comfortably: in garages, utility rooms, exterior walls under cover, or near switchboards or meter panels.
It has a popular, clean, sleek aesthetic that makes it suitable for installations in both residential and commercial settings.
| Modules | Battery Capacity (kWh) | Usable Capacity (kWh) | Approx. Runtime |
|---|---|---|---|
| 1 module | 10.1 kWh | 9.7 kWh | 1 hour 56 minutes |
| 2 modules | 20.2 kWh | 19.4 kWh | 3 hours 53 minutes |
| 3 modules | 30.3 kWh | 29.1 kWh | 5 hours 49 minutes |
| 4 modules | 40.4 kWh | 38.8 kWh | 7 hours 46 minutes |
| 5 modules | 50.5 kWh | 48.5 kWh | 9 hours 42 minutes |
| 6 modules | 60.6 kWh | 58.2 kWh | 11 hours 38 minutes |
Runtimes vary based on load behaviour. Homes rarely run at full output, meaning real-world runtime is typically longer.
The Alpha Smile 5 carries dual protection ratings:
With an operating temperature range of –10°C to 50°C, it's engineered for Australian climates—from cold southern regions to hot northern summers. Installers can position the system wherever it best suits your property layout.
Yes.
Because the Smile5 has an inbuilt hybrid inverter, it can be installed:
This is one of the Smile5's strongest advantages. Its in-built hybrid inverter allows the battery to work alongside almost any existing solar system without requiring homeowners to replace their current inverter. That makes retrofitting simpler, faster, and more affordable.
