An honest, no-spin assessment of home battery storage — when it makes financial sense, when it does not, and what is actually involved in getting one installed.
A home battery stores excess electricity generated by your solar panels during the day and releases it when you need it — typically in the evening and overnight when solar production drops to zero but your household is still using power.
Without a battery, that excess solar energy is exported to the grid. You receive a feed-in tariff — currently between 5 and 10 cents per kWh on the Sunshine Coast depending on your retailer. With a battery, you store that energy and use it yourself, avoiding the need to buy it back from the grid at 25 to 35 cents per kWh. The difference between what you would have been paid for the export and what you would have paid for the import is where the savings sit.
The federal Cheaper Home Batteries Program has changed the economics of battery storage in Australia. The program provides interest-free loans and upfront rebates that reduce the effective cost of a home battery system significantly.
For eligible households, this program can bring the payback period down from 10 or more years to something closer to 6 to 8 years. The exact benefit depends on the battery size, your electricity consumption patterns, and how much solar you are already generating.
Leading Edge can advise on eligibility and help you navigate the application process as part of a battery installation assessment.
The integration is straightforward. During the day, your solar panels generate electricity. Your home uses what it needs first. Any excess is directed to the battery until it is fully charged. Once the battery is full, any remaining excess is exported to the grid.
In the evening and overnight, your home draws from the battery instead of the grid. When the battery is depleted, the home switches back to grid power automatically. The whole process is managed by the battery’s built-in inverter or a hybrid inverter, with no manual intervention required.
Most modern battery systems also include monitoring apps that show you real-time energy flows — what your panels are producing, what the battery is storing or discharging, and what you are drawing from the grid.
Battery storage delivers the strongest return on investment in the following scenarios:
We are straightforward about this — a battery is not the right investment for every household. Consider holding off if:
Installing a home battery is not a plug-and-play exercise. It requires a licensed electrician with experience in battery systems. Here is what is involved:
We assess homes for battery readiness across the Sunshine Coast. This includes evaluating your solar system, switchboard, electrical load profile, and physical installation location. We give you an honest recommendation — including whether a battery is the right move for you right now or whether you would be better served by a different investment first.
If a battery does make sense, we handle everything from system selection through to installation, commissioning, and compliance certification.

A quality home battery system typically costs between $8,000 and $16,000 installed, depending on the capacity and brand. With the Cheaper Home Batteries Program, the effective cost can be reduced significantly through rebates and interest-free finance. We provide a clear, itemised quote after assessing your home.
Most quality battery systems are warranted for 10 years and designed to retain at least 70% of their original capacity at the end of that period. Real-world lifespan often exceeds the warranty period. Battery technology is maturing, and the reliability of current-generation systems is significantly better than early models.
It depends on the battery size and your consumption. A standard 10 kWh battery can power essential circuits — lights, fridge, internet, a few power points — for several hours. It will not run your entire home including air conditioning, oven, and hot water simultaneously. During installation, we set up a backup circuit board that prioritises the circuits you need most during an outage.
