About Alpha SMILE5 10.1 Solar Batteries

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 10.1kWh of storage per unit. It can expand up 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 10.1kWh 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.

Power Most Daily-Use Appliances Simultaneously

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.

Fast, Efficient Charging & Discharging

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.

UPS Backup For Instant Protection During Blackouts

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:

Families working from home
Households with medical equipment
Anyone wanting reliable blackout protection

Please note: Activating blackout protection is an opt-in feature with added cost to cover additional labour, such as modifications to your building switchboard.

Warranty

5 Years Product Warranty
10 Years Battery Performance Warranty (backed by Munich Re)

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.

Compact All-In-One Power

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
Near switchboards or meter panels

It has a popular, clean, sleek aesthetic that makes it suitable for installations in both residential and commercial settings.

Estimated Battery Runtime

At 5 kW continuous output (hybrid inverter)

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.

Rated for Safe Installations Indoors or Outdoors

The Alpha Smile 5 carries dual protection ratings:

IP21 for indoor installation
IP65 for outdoor installation

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.

Does the Smile5 10.1 support retrofitting?

Yes.

Because the Smile5 has an inbuilt hybrid inverter, it can be installed:

With new solar panels, or
As a retrofit on homes that already have solar, even if their existing system has a non-hybrid inverter.

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.

Frequently Asked Questions

Is the Alpha Smile 5 easy to install?

Yes, the Alpha Smile5 is designed for simple, flexible installations. It’s one of the most adaptable solar battery systems available for Australian homes. The Alpha Smile5’s inbuilt hybrid inverter eliminates the need for separate components, which streamlines the entire installation process and reduces both cost and complexity. With the inverter already integrated into the system, there are fewer parts to mount, fewer cables to run, and fewer potential points of failure. This results in a cleaner setup that is quicker to install and easier to maintain.

Because everything is consolidated into a single, well-engineered unit, the Smile5 can be installed in a wide variety of home layouts. It suits garages, utility rooms, and outdoor areas with its strong IP protection ratings. Installers can position it close to the switchboard, near existing solar infrastructure, or in tight spaces where traditional multi-component systems would not fit. The integrated hybrid inverter also gives homeowners more flexibility in how they operate their energy system, since it can manage both solar generation and battery storage without requiring additional hardware.

This smart all-in-one design means faster installation times, a tidier appearance on your wall, and fewer complications down the track.
