About Alpha-ESS, Solar Batteries

Alpha-ESS solar batteries review

Energy storage manufacturer Alpha ESS was established in 2012. A Chinese company, it has offices in Australia, the UK, Germany and Italy.

In Australia, the main Alpha-ESS product line is the Storion SMILE. This is an all-in-one unit, meaning the system includes batteries, a battery management system (BMS) and an inverter.

The battery modules used in the Storion SMILE are lithium iron phosphate chemistry; widely considered the safest type of lithium ion battery technology.  Alpha-ESS sources battery modules from another Chinese company, EVE, which has been in the battery business since 2001. 

The Storion SMILE range is available in various capacities and AC/DC/Hybrid coupling options are available. This unit does have blackout protection capabilities. As for power output, that varies with the model - for example, the 5.5kWh model has 2.8kW nominal output, while the 16.5kWh is 4.6kW. 

Alpha ESS Warranty

The warranty for Alpha ESS solar batteries guarantees a minimum of 80% of their original capacity after 10 years, assuming the system is connected to the internet and is only used for self-consumption. If the system is not internet connected, the warranty plummets to three years. 

If the system is used for puposes other than self-consumption, assumed to include use as part of a Virtual Power Plant (VPP), the warranty will expire earlier - when total energy of 2.92MWh per kWh of usable capacity has been dispatched from the battery.

We haven't heard a lot of how these batteries are doing in real-world conditions in Australia, so if you're an Alpha-ESS battery owner we'd really appreciate you adding your review by clicking the button towards the top of this page.

Alpha-ESS Solar Battery Reviews

A bit early to tell conclusively but at this stage very happy with the performance.

I'm disappointed......At my previous property, I had a Tesla Powerwall 2 - it provided automatic backup on mains/grid failure, and the solar panels kept working.
This system, with 2 x 10.1KwH batteries, requires manual switching on mains powerful, and solar panels cease working......
To be fair, the later issue (existing solar panels ceasing) is because i have two submarines- solar panels on one (on the shed), and the battery on the other (house).
Shinehub did a pre-instal inspection and noted my expectations.....but the installation did not deliver.....
The Tesla Powerwall offered fuil backup....Shinehub (so I've now discovered) only provided for lights, the fridge circuit and the modem circuit...
Very disappointed.
