As electricity prices continue to climb and power outages become more common in many parts of Australia, more households are turning to solar energy—not just for sustainability, but for long-term cost savings and energy independence.

While installing solar alone can significantly reduce your power bills, pairing it with a home battery takes your system to the next level. That’s where Sungrow solar batteries come into play—offering reliable storage, backup capability, and smart scalability.

In this blog, we’ll explore the most popular solar + battery combos for Aussie homes—built around the country’s best-selling sizes: 6.6kW and 13.2kW systems. We’ll break down battery options including 9.6kWh, 10kWh,12.8KWH , 15kWh, 19.2KWH ,20kWh, and 25kWh Sungrow models, to help you find the right setup for your energy needs and budget.

Why Pair a Battery with Your Solar System?

A battery transforms your solar setup from a simple daytime solution into a 24/7 energy source. Here’s how:

Store Excess Solar: During the day, your solar panels often generate more energy than your home uses. Instead of sending it back to the grid for a small credit, store it for use later.
Use Solar at Night: Batteries allow you to run your appliances, lights, and air con after the sun goes down—without paying peak electricity rates.
Save on Peak Charges: Many utility providers charge higher rates during the evening. With a battery, you can avoid those charges altogether.
Backup in Blackouts: Certain Sungrow battery setups can provide backup power during grid outages, offering peace of mind and uninterrupted energy.
Improved ROI: By maximising solar usage and reducing your power bills further, a battery can shorten the payback period of your entire system.
