Alpha ESS offers various battery models to cater to individual needs, such as SMILE-5, SMILE-G3 and SMILE-T10, with the Alpha ESS SMILE5 being one of their popular models. The Storion SMILE5 utilizes lithium iron phosphate chemistry in its battery module, ensuring safety and efficiency for the battery modules.

The storage capacity of SMILE-5 is 10.1 kWh and 13.3 kWh, making it a suitable option for solar battery storage. The SMILE-G3 has a storage capacity of 10.1 kWh, presenting another viable choice for solar battery systems.

The SMILE-T10 offers a storage capacity of 8 kWh and 16 kWh, contributing to an efficient energy storage system.

Installation and Compatibility

Alpha ESS batteries are versatile and compatible with both new installations and existing solar PV systems, making them an ideal choice for those with solar panels. However, it’s important to note that there is a 3-4% inefficiency when AC coupling an Alpha ESS battery system.

The Storion SMILE5 offers AC/DC/ hybrid coupling options, allowing for seamless integration with various solar power setups. This flexibility ensures that your Alpha ESS battery can be easily incorporated into your existing or new solar system.

Safety and Performance

Safety is a paramount concern when it comes to investing in solar batteries. Alpha ESS batteries feature lithium iron phosphate (LiFePO4) chemistry, which is known to be safer and have a longer life cycle than traditional lithium-ion batteries. Lithium iron phosphate batteries are deemed more secure than lithium-ion batteries owing to their high chemical and thermal stability, rendering them non-flammable and able to withstand higher temperatures in the event of a short-circuit or overcharge.

In addition to their safety features, the SMILE5 series possesses blackout protection capabilities, making it a reliable choice for solar battery storage during power outages.

Pricing and Return on Investment

The price range of 10.1 kWh battery is $10,500 and 13.3 kWh battery is $11,500. But for real time quote based on your location, call our experts at Austra Solar.

Alpha ESS batteries are known for their affordability, but it’s essential to balance the cost against potential savings on power bills when evaluating the return on investment. To help you choose the right solar battery system for your needs, a price guide for different battery capacities based on data from Solar Choice’s Battery Price Index is available.

The cost per kilowatt-hour (kWh) basis of the Alpha ESS solar battery range has enabled the adoption of a lithium battery energy storage system to be a more viable option than previously thought. However, customer feedback on Alpha ESS solar batteries typically falls into two categories: satisfaction with the battery’s installation and performance at an affordable cost, and frustration due to issues encountered..

Warranty and Customer Support

Alpha ESS offers varying warranties for their solar battery storage systems.

  • The warranty for the most of batteries by Alpha Ess in Australia is 10 years.

  • There are options to extend the warranty at an additional cost.

  • The warranty for the inverter and all components other than the battery modules is five years.

These warranties ensure the reliability of your solar battery storage.

It is important to note that if the AlphaESS battery system is not connected to the internet, the battery warranty will be limited to 3 years, and the claimant will be responsible for arranging an inspection of the system at their own expense.

Government Incentives and Rebates

In Australia, various states offer government incentives and rebates for home battery installations, thereby making Alpha ESS batteries more accessible for those with solar panels. For example, the SA Solar Battery Subsidy is a government incentive that offers a rebate of up to $6,000 for the installation of a solar battery system in South Australia.

Another example is the Next Generation Battery Storage Program by the ACT government, which provides a rebate of up to $3,000 for the installation of an energy storage system, such as a solar battery, in the Australian Capital Territory. These incentives and rebates vary depending on the state or territory but aim to promote the adoption of solar power and energy storage solutions like Alpha ESS batteries.

Energy Security and Environmental Impact

Alpha ESS batteries are engineered to ensure energy security through the storage of energy for future use and reliable and stable energy supply, aided by an integrated battery management system. This is particularly important during power outages, when a reliable source of energy is essential.

By investing in Alpha ESS batteries, you are also contributing to a sustainable future by reducing your reliance on fossil fuels. The widespread adoption of solar batteries can significantly decrease the environmental impact of energy consumption and promote the use of renewable energy sources.

Comparing Alpha ESS to Other Solar Battery Brands

When comparing Alpha ESS to other solar battery brands, such as Tesla and Senec, it’s important to consider factors such as:

  • Price

  • Performance

  • Warranty

  • Compatibility with your solar system

Alpha ESS is widely regarded as one of the leading solar battery systems brands and has been evaluated by ITP Renewables, featuring in numerous solar battery comparison tables.

However, as per our solar industry experts, recommends that if you are seeking a more economical battery, you may want to consider investing a bit more and acquiring a Sungrow, Growatt or Solax. This highlights the importance of evaluating all factors and comparing multiple solar battery brands before making a decision.


In conclusion, Alpha ESS solar batteries offer an affordable and efficient energy storage solution with various models and storage capacities to suit individual needs. Their safety features, compatibility with both new installations and existing solar PV systems, and available government incentives and rebates make them an attractive option for those looking to invest in solar battery storage.
