Solar battery storage allows you to store excess electricity generated by your solar PV system and use it later, when you need it most. Instead of exporting surplus energy back to the grid during the day, a battery keeps that power available for the evening, overnight, or during periods of higher electricity prices.
By adding battery storage, your home becomes less dependent on the grid and more in control of its own energy. It’s one of the most effective ways to maximise the value of your solar PV system.
When your solar panels produce more electricity than your home is using, that surplus energy is directed into a battery rather than being lost or exported. The battery safely stores this electricity until it’s needed.
Later in the day — typically in the evening — your home automatically draws energy from the battery before importing power from the grid. This happens seamlessly in the background, with no manual switching required. The system always prioritises the most cost-effective and efficient energy source available.
Modern battery systems are fully integrated with your inverter and home electrics, continuously monitoring usage, generation, and storage to keep everything balanced and efficient.
Battery storage allows you to make the most of the electricity you generate. Instead of exporting unused solar energy back to the grid during the day, a battery stores it so you can use it later — in the evening, overnight, or when demand in your home is higher.
For many households, this dramatically increases self-consumption. Without a battery, much of your solar generation is used while the sun is shining, often when you’re out or using very little power. A battery bridges that gap, letting your home run on stored solar energy when the panels are no longer producing.
Battery storage also helps protect you from rising electricity prices. By reducing how much power you need to buy from the grid at peak times, you gain more control over your energy costs and reduce exposure to future price increases.
In the event of a power cut, certain battery systems can provide backup power to essential circuits, keeping lights, internet, and key appliances running when the grid goes down (subject to system design).
Batteries aren’t just for solar homes either. When paired with smart tariffs, they can charge during off-peak periods when electricity is cheaper and discharge during expensive peak hours, further reducing bills and improving efficiency.
