With the recent sudden declines in in the cost of battery storage systems, many Australians are looking towards batteries as a viable solution for the current energy crisis and a means to eliminate their electricity bills altogether.
But like many Australians, you may be asking what exactly are battery storage systems and how do they work to power my home?
How do they store my energy?
As you may have read in the benefits of battery technology, solar energy is generated from your solar PV panels harnessing the sun’s energy during the day to power your home. The downside is that around 6pm every day, the sun goes down and your panels can’t convert any more energy. This is where batteries become very useful. With the addition of a battery you are able to store your energy after it’s been generated during the day to be repurposed during the night. All of this stored energy can power your home for the entire night, resulting in your own private sustainable energy generating home.

What goes into a battery and selecting one for my home?
Batteries are either lithium-ion based or lead-acids based, and create a chemical process to store the electrical energy you’ve gained during the day from the solar PV panels you have sitting on your roof. Batteries range in a general small size of around 3.3 kilowatts to 9.8 kilowatt hours (with kilowatt hours being a measure of energy, not time). Depending on the size of your home’s energy consumption and how independent from the grid you want to be, will determine what size battery system is best for you.
How do batteries connect to my home?
Batteries connect to a home in two main ways. Either DC (direct current) or AC (alternating current) coupled. A DC-coupled battery storage system is directly integrated into the solar system itself, generally containing a single inverter which converts the stored DC electricity into AC energy. This stored energy can then be directed to either power your home or feed itself into the energy grid where you will be reimbursed by the Government as an energy supplier. The alternative in AC-coupling is where the battery storage system is independent to the solar system. The battery is then directly connecting to your house wiring through a bi-directional battery inverter to charge the battery and then discharge it straight to the home.
