While most Australian homes with solar systems currently operate without batteries, the number of batteries being installed is increasing. Falling feed-in tariffs, coupled with increasing emphasis on energy security and reducing carbon footprints, are driving more homeowners to consider adding a battery to their solar setup. But is it worth the investment? Let’s explore the benefits and options for integrating solar batteries into your home.
Advantages of adding a battery to your solar system
- Cost Savings: Store excess solar energy generated during the day and use it during peak evening hours to lower your electricity bills.
- Reliable Power: Many batteries can keep your home powered during grid outages, ensuring uninterrupted electricity.
- Virtual Power Plants (VPPs): By joining a VPP such as Amber Electric, your battery can support the grid during high-demand periods. In return, VPP operators may compensate you generously for allowing temporary control of your battery.
- Environmental Impact: Minimise reliance on the grid and maximise the use of renewable energy, significantly reducing your household’s carbon emissions.
Best Batteries for Existing Solar Systems
If you already have a solar system, compatibility is key when choosing a battery. For most existing setups, an AC-coupled or all-in-one battery with a built-in inverter is the go-to option. These batteries convert power to DC for storage, making them compatible with nearly any solar system.
Popular AC-coupled battery options include:
- Sigenergy
- Deye
- Alpha ESS
For those with a hybrid inverter, a DC-coupled battery from the same manufacturer is often the best fit. These installations are typically more cost-effective and integrate seamlessly with your existing monitoring app.
