If you’ve been thinking about installing a home battery, 2025 is a great time to make the move. The newly launched federal Cheaper Home Batteries Program, which came into effect on 1 July 2025, offers an upfront discount of around 30% on the total installed cost for eligible systems. This is an excellent opportunity for Victorian households, especially when combined with Solar Victoria programs (where available) and the state’s ongoing push towards electrification.

Who Benefits Most from Home Batteries?

• Households with existing solar: If you already have a solar system and find that you’re exporting a lot of energy during the day, a battery can help you store that excess energy to use at night. This reduces your reliance on expensive grid power after the sun goes down!
• Families with evening energy needs: Whether it’s for cooking dinner, laundry, heating, or running a home office, families that use a lot of energy in the evenings can benefit from having a battery. It allows you to rely on stored solar power rather than paying for energy from the grid.
• Areas prone to power outages: For those living in regions where power outages are common, a home battery can provide much-needed backup power, ensuring that your home stays connected during blackouts or other interruptions.

Key Takeaways in Simple Terms

1. A battery lets you store solar energy for later use: By storing surplus solar power during the day, you can use it at night, which reduces your reliance on grid electricity during peak hours when prices are higher.
2. The federal discount is applied upfront: The discount is applied directly at the point of sale by approved retailers and installers. This means you get the savings immediately, making it easier to see how much you’ll actually pay for the system.
3. Payback period is improving: With feed-in tariffs decreasing, daytime electricity is becoming cheaper, while evening electricity costs are rising. This makes home batteries even more worthwhile, as you can use the stored energy during those expensive peak periods, making your investment pay for itself quicker.
4. Future-proof your home with electrification: If you’re planning to upgrade your home to be more energy-efficient, such as installing a heat pump for hot water, using reverse-cycle heating and cooling, or switching to induction cooking, adding a battery ensures that you can get the most out of your renewable energy setup and avoid high energy costs in the future.

What to Check Before You Buy

Before purchasing a home battery, there are several factors you’ll want to consider ensuring you choose the right system for your home and energy needs:

• System size and your usage: The first step is to look at your electricity bills to understand your daily consumption (measured in kWh/day). You’ll also need to consider your night-time energy needs. For a typical family home, a 10–15 kWh battery is usually a good fit.
• Hybrid vs. AC-coupled systems: A hybrid system integrates both the battery and the solar inverter into one unit, which is convenient for new installations. If you already have a solar system in place, an AC-coupled battery system might be a better choice, as it works well with existing setups and offers more flexibility.
• Virtual Power Plant (VPP) compatibility: Some battery systems can be linked to a Virtual Power Plant (VPP), which allows you to sell excess energy back to the grid for credits on your electricity bill. If this is something that interests you, ensure the system you choose is VPP-ready.
• Compliance and warranty: Make sure the system you’re considering is accredited by the Clean Energy Council (CEC) and is compatible with VPP networks. You’ll also want a warranty that is simple to claim on, in case you need repairs or replacements down the line.

Typical Next Steps in the Home Battery Installation Process

1. Review your energy bills and consumption: The first thing you need to do is assess how much energy your household uses and when. This will give you a better idea of what size battery you need.
2. On-site or virtual assessment and system design: Once you have a clearer idea of your needs, a qualified installer will assess your home and design a system that suits your energy consumption.
3. Get a quote with rebates applied: After the assessment, you’ll receive a quote that includes the federal rebate, giving you a clear idea of how much the system will cost you upfront.
4. Installation and app setup: The next step is installation, which is carried out by an approved installer. They’ll also help you get the system set up with any associated apps that allow you to monitor your energy usage and battery status.
5. Post-installation check-in: Once your battery is installed and running, expect a follow-up from your installer to make sure everything is working properly and that you know how to optimise the system for your home.
