Installing solar is a smart move—but for many Brisbane homeowners, it’s only half the equation. As power prices continue to rise and energy independence becomes more valuable, the question isn’t if you should add a battery, but which battery is right for your home.
For those considering a solar system with a battery, Growatt offers safe, reliable, and scalable options to store solar power and use it when it matters most—after sunset, during blackouts, or during peak rates. The same applies to homeowners running larger systems like 13.2kW, who want to future-proof their energy use.
In this guide, we break down how Growatt batteries pair with both 6.6kW and 13.2kW solar systems, what each combo is ideal for, and how to decide what fits your household best
Why More Homeowners Are Upgrading Their Solar with a Battery
A solar system without a battery is like a phone without a charger—it works, but only while the sun’s shining. Adding a battery turns your solar setup into a 24/7 energy solution.
Here’s what a battery adds to your system:
- Evening Energy, On Your Terms
Save excess solar during the day and use it when you need it—after the sun goes down. - Less Grid, More Freedom
Cut down on electricity costs by reducing how much power you draw from the grid. - Power When It Matters
Keep the essentials running during outages, depending on your system’s configuration.

What About the Price?
The 6.6kW or 13.2kw solar system with battery price varies depending on battery size, inverter compatibility, installation specifics, and available rebates in Queensland.
What Affects the Price:
- Battery capacity (10kWh vs 25kWh makes a big difference)
- Installation complexity (roof type, cabling, inverter type)
- Existing system compatibility
- Government rebates or incentives
While upfront costs are higher with battery-backed systems, the long-term savings and energy control more than justify the investment—especially in households with high night-time usage or rising power bills.
