Batteries

Solar energy powers your home during the day, with excess energy exported to the grid. Shortfalls, typically in the morning, evening, or during cloudy weather, are covered by importing grid electricity. A solar battery system helps reduce costs by storing excess energy for use during peak times when electricity rates are higher. Once the battery is full, any additional solar power is exported. If a backup system is installed, the battery can power essential circuits during grid outages until service is restored.

Yes. Homeowners can benefit from both federal and state government battery rebates to which they are eligible. As an accredited supplier, Smart Energy is uniquely positioned to handle the rebate process for you, ensuring you reduce your upfront costs and maximise your savings.

The duration a 10 kWh battery lasts depends on how much power your household or connected devices consume. For lower energy usage, such as powering a fridge, some lights, and electronics, it can last around 5–10 hours. For moderate use, including lights, a fridge, and occasional air conditioning, it might last 2–3 hours. 

If you’re running high-energy appliances like air conditioning or a pool pump, the battery may last only 1–2 hours. 

Keep in mind that most batteries aren't designed to discharge fully, and efficiency losses during charging and discharging can slightly reduce the total available power. Actual durations will vary based on your energy consumption patterns.

Installing solar and a battery is one of the most powerful ways to take control of your energy, slash your bills, and protect yourself from rising electricity costs. With solar panels, you generate free energy from the sun during the day, reducing your reliance on the grid. Adding a battery takes it to the next level—storing excess solar power so you can use it at night or during peak times when electricity is most expensive.

But the benefits don’t stop there. A solar and battery system sets you up for the future, making it easier to transition to an electric vehicle and power it with your own free energy instead of expensive petrol. It also opens the door to home energy management systems that help you optimise when and how you use power, supercharging your savings. Beyond just cutting costs, you’re also gaining true energy independence—less affected by power price hikes, grid outages, or extreme weather—while significantly reducing your carbon footprint.

Whether you’re looking to future-proof your home, increase its value, or enjoy the freedom of producing and using your own clean energy, solar and batteries are an investment that pays off in more ways than one. Smart Energy can help you design the perfect setup to maximise your savings and take full advantage of this exciting shift towards smarter, cleaner energy.
