Alpha ESS Battery Review For 2023 By Solar Emporium

Alpha-ESS is one of Australia’s leading solar battery brands. They have competed with global competitors with an impressive 300% annual growth rate.  

Their production capacity is also noteworthy. They are producing up to 1 Gigawatt of batteries annually. 

Their popularity in the residential market prompted us to make this review. So here goes the Alpha ESS battery review for 2023 by Solar Emporium.

Background on Alpha ESS

Alpha ESS stands out for its commitment to offering comprehensive training and support to installers, engineers, and consultants.  

With a user-friendly installation process and a monitoring platform, users can be confident that their battery will seamlessly integrate with their solar system. And it will ensure optimal performance for years. 

Alpha ESS, a Chinese energy storage systems manufacturer, primarily caters to residential and commercial markets on a global scale.  

The acronym “ESS” comes from “Energy Storage System.” Founded in 2012, the company recently relocated its headquarters to Suzhou, China. Alpha ESS operates through over ten local subsidiaries and offers services in more than 50 countries. 

In 2015, Alpha ESS established an office in Australia and quickly became a part of the South Australia home battery scheme in 2018. Soon after, they started production at full capacity.  

Alpha ESS produces a range of products. The Smile series is for the residential energy storage market. The Storion series is designed for the commercial sector. And an industrial-scale battery enclosed within a shipping container.

Product Information

Alpha-ESS has a huge range of commercial batteries. On the residential side, Alpha-ESS has the Smile Series with different ranges of solar battery sizes to suit all residential purposes. 

Unlike competitors like Tesla and LG, with just one model, Alpha-ESS gives you three size options to fit your energy requirements – 5.7, 10.3 and 13.3 kW.

Alpha ESS Residential Battery System – Alpha ESS SMILE

Alpha ESS battery

The Alpha ESS Smile series is designed for residential purposes. This series unifies a hybrid inverter, a battery system, and a storage unit to accommodate separate ‘battery modules’ for capacity expansion.  

The hybrid inverter serves a dual purpose. It sends solar power directly to the household. In real-time, it converts battery power to usable AC power. While you buy the batteries separately, they integrate into a single aesthetically pleasing unit. 

During a blackout, the Alpha ESS system can supply clean power to a home or business. Importantly, this technology is built into the system, eliminating the need for additional costs or components, contrasting to other battery systems.
