Battery Hardware Price vs Installed Battery Price
When comparing home battery prices in Australia, check whether the advertised amount refers only to the battery hardware or to a complete installed system.
Battery Hardware Price
A hardware-only price may cover the battery unit but exclude installation, additional inverter equipment, backup hardware, electrical work and other site requirements.
Installed Battery Price
An installed quotation should identify the equipment and installation scope, while also making clear any additional work that may be required after site assessment.
What Size Solar Battery Do I Need?
The right battery is not necessarily the largest one you can afford. Battery capacity should be matched to your household’s energy profile.
Important information includes:
- Average daily electricity consumption
- Daytime electricity consumption
- Evening and overnight consumption
- Existing solar system capacity
- Average solar exports
- Seasonal energy use
- Air-conditioning loads
- Pool or spa equipment
- Electric hot water
- EV charging requirements
- Desired blackout backup duration
A battery that is consistently too large for the available surplus solar may not be fully charged from rooftop solar, while an undersized battery may not store enough energy for the household’s evening requirements.
5kWh vs 10kWh vs 15kWh vs 20kWh Battery
| Battery Size | Potential Use | Household Consideration |
|---|---|---|
| 5kWh | Basic evening energy storage | Lower-consumption households |
| 10kWh | Moderate evening and overnight storage | Small to medium households |
| 13–15kWh | Greater evening and overnight storage | Medium to larger households |
| 20kWh | Higher storage requirement | High-use and more electrified homes |
| 25–30kWh+ | Large residential energy storage | Large homes, EV charging and substantial overnight loads |
These are general profiles only. Actual battery sizing should be based on your electricity data and solar-generation profile.
Can I Add a Battery to My Existing Solar System?
Yes, in many cases an existing Australian solar system can be upgraded with battery storage. The existing inverter, solar array, electrical supply and switchboard should first be assessed for compatibility.
