Alpha ESS Battery Range

General Company Information

Alpha ESS is a Chinese battery manufacturer. They have been around for 10 years, founded in 2012. As per their website, they produce 1000MWh of batteries every year and ship over 75,000 products around the world since theory inception. They do everything from small residential batteries to huge grid scale beasts. They have won quite a few awards over the years and in our opinion, their products have come leaps and bounds in the last few years.

Outside of batteries they are also moving into the production of EV chargers (makes sense) which we will start to see rolled out imminently.

How Do They Work?

Alpha mostly focuses on all in one batteries. What that means is, the battery and battery inverter and one unit. Outside of that, they work much like a solar battery should. They store any excess solar you generate in your battery for use later when you need it. For example, at night when power prices go up and the sun goes down.

They can also do cool things like download power from the grid when it is cheap if your generation of solar isn’t enough to fill the battery. However, we wouldn’t think too much about that element. If your solar isn’t supporting your battery, it is worth considering more solar if you have the space and not get too focused on time of use downloading.

What Are Alpha ESS Batteries Made?

China. They do have an assembly facility in South Australia however everything is actually made in China.

How Long Is The Warranty On Alpha ESS Batteries?

The warranty can vary from product to product. In most cases you will find they come with a 5 year product and 10 year performance warranty. You can upgrade most of their 5 year product warranties up to 10 years for a fee, and it must be done when the battery is initially bought and installed. It is best practice given the warranty can differ to confirm the warranty on the exact battery you are purchasing.

We say some because we will do our best to include all of their residential batteries below but sometimes they release a new product or change something and we haven’t had a chance to update this page.
