ADD A BATTERY TO EXISTING SOLAR SA
Already have solar? Add a battery to it
If you have solar, you probably export most of what it makes in the middle of the day for a few cents, then buy power back at night at full price. A battery stores that daytime solar so you use it after dark instead.
Most systems in South Australia can take a battery without replacing the panels. We check your inverter and switchboard, then recommend the battery that suits what you already have.
Signs a battery will pay off
- Your bill shows big evening and overnight use
- You export much more than you use during the day
- Your feed-in tariff has dropped
- You want backup power in a blackout
THE BATTERIES WE INSTALL
Tesla Powerwall 3, Sigenergy and GoodWe
- Tesla Powerwall 3. Can be added alongside most existing systems. We are a Tesla Energy Certified Installer.
- Sigenergy. Modular, so capacity can be added later.
- GoodWe. A good match for many existing GoodWe inverters.
Will it work with my inverter?
Some batteries connect to your existing inverter; others bring their own. Where your inverter is old or near the end of its life, it can make sense to replace it with a hybrid inverter in the same job. We explain the options and costs before you decide.
THE REBATE
The battery rebate steps down on 1 January 2027
The federal battery rebate takes a share off the price of an eligible battery, and we work it into your quote. The rebate is set by the date the battery is installed, not the date you sign.
- It steps down on 1 January 2027, and again on 1 July 2027.
- Since 1 May 2026 it is tiered by size: the full rate up to 14 kWh, a reduced rate from 14 to 28 kWh, and a smaller rate from 28 to 50 kWh.
- Small businesses can claim it too.
We handle the SA Power Networks approval and the Relevant Agent setup. If your switchboard needs work first, we do the switchboard upgrade in the same job.

COMMON QUESTIONS
Battery add-on questions
Usually, yes. We check your inverter and switchboard first and recommend a battery that works with them.
Not always. Some batteries connect alongside your existing inverter. If yours is old or failing, replacing it in the same job can be the better option.
It depends on the battery’s size and the install date. It steps down on 1 January 2027, and we show the rebate on your quote.
We size it from your power bills: how much you use after dark, how much solar you export and whether you want backup.
Only if it is set up for backup, which can need extra switchboard work. We explain the options and cost when we quote.
Yes. If your system is small, adding panels with the battery can make sure it fills each day.
