Home Batteries in Australia: The Market, Applications, and Results

by Adam Champion on March 2, 2017 at 5:30 PM

Australia is quickly becoming one of the leading markets for residential energy storage.

There are a few key reasons for why this enthusiastic uptake of home batteries is happening:

  • Australians already love solar power. Government incentives over the last 10 years have helped enable the installations of more than one million residential solar roofs. So, solar PV technology is in just about every neighborhood.
  • Australians use a lot of energy with a significant portion driven by air conditioning loads.
  • Some generous solar feed-in tariffs (rates of up to 60 cents/kWh for all energy created) have now come to an end. This means that for many households excess solar generation is now earning them very little.

Crowdfunded Energy Storage: Circuitree Cirrus with Saltwater Batteries

by Claire Juozitis on February 23, 2017 at 2:54 PM

Integrated energy storage systems are the popular new toys on the market. 

These plug-and-play, standalone systems combine the various components of an energy storage system (batteries, inverters, controllers, etc.), making it easier for small businesses and homeowners to hit the ground running with solar energy storage. Our partners Sentinel Solar in North America and Fusion Power Systems in Australia have developed these kinds of solutions using our saltwater batteries, and so far they’ve been a hit.

Now, another smart battery solution is being developed to power homes in the United Kingdom, but with an interesting angle: it’s crowdfunded!

New Solar Battery Safety Policies for Australian Homeowners

by Aquion Team Member on February 17, 2017 at 12:17 PM

The possibility of new regulations restricting lithium-ion battery installation in Australian homes could have a major impact on the energy storage industry.

Safety concerns surrounding lithium-ion batteries have inspired a variety of policy initiatives restricting their usage in homes or densely populated cities.  For instance, in November, New York City’s fire department and the New York State Energy Research and Development Authority (NYSERDA) convened to address the very real concern about lithium-ion-related fires in New York City and commissioned a study on how to handle potentially flammable storage systems in an already complex and outdated New York City grid.  Perhaps piggybacking off that initiative, the issue has once again become a hot topic - this time in Australia as officials with Standards Australia are proposing tough new rules for the installation of lithium ion batteries in homes.

Partial State of Charge and Solar Telecom Batteries

by Terry Holtz on February 12, 2017 at 3:00 PM

In off-grid telecom sites with energy storage, the solar batteries are usually sitting at a partial state of charge, meaning they are not fully charged, nor fully discharged.

Solar-powered telecom towers commonly have lead acid batteries for their energy storage systems. However, operating or even sitting idle at a partial state of charge is problematic for lead-acid batteries.  As lead acid batteries discharge, the active materials transform from lead to lead sulfate - it is this chemical reaction that provides the requested power.
