Home batteries

Advantages of home batteries

A common question for people getting solar, and those who have it already, is: should I add a battery? While the upfront cost is significant, there are advantages to having a battery:

  • Energy when you need it: If you have solar panels, a home battery will store excess energy generated during the day for use at night. This reduces the need to buy energy from the grid during non-sunny hours.
  • Time-of-use optimisation: Many energy companies charge higher rates during peak hours when demand is at its highest. A home battery can be programmed to discharge during these peak times, saving you money by using your stored solar energy.
  • Blackout protection: One of the standout features of home batteries is their ability to provide backup power during blackouts (although not all batteries have this feature). When the grid goes down, your battery steps in, so you can keep the lights on, still access WiFi, and not worry about your freezer defrosting.
  • Reduced energy bills: By storing excess energy and using it during expensive peak times, you can significantly lower your monthly energy bills.
  • Environmental benefits: Utilising stored energy during peak demand times reduces the strain on power plants, leading to a decrease in greenhouse gas emissions and a smaller carbon footprint.
  • Independence from grid fluctuations: Home batteries grant you greater control over your energy supply, reducing your vulnerability to grid failures or fluctuations in energy prices.

Choosing the right home battery

Selecting the appropriate home battery for your needs involves considering factors such as capacity, power output and compatibility with your existing energy systems. You'll also want to assess the battery's lifespan and warranty to make sure it’s a reliable investment.

Making the transition to home batteries

Transitioning to home batteries requires careful planning:

  • Energy usage assessment: Take note of how much energy you use, and when you use it, along with your solar set up, if you have one. These will all influence the best battery size and type for your home.
  • System integration: If you already have solar panels, consult with a solar professional (e.g. RACV Solar, one of Victoria’s largest home battery installers) to integrate your battery with your existing solar system. If you don't have solar, the battery can still be charged from the grid during off-peak times.
  • Financial considerations: Explore available incentives, rebates/loans (such as a Solar Victoria interest-free loan) and financing options that can make the upfront cost of a home battery more manageable.
