Compare Solar
Batteries in Australia
Solar batteries are key to energy independence—storing excess power for use when you need it most.
Use a battery compare chart to evaluate systems side by side using essential specs like usable capacity, cycle life, and peak power output—so you can choose a solution that matches your energy needs, backup requirements, and long-term value.
Built for Australian conditions, the right battery helps maximise efficiency, reliability, and future scalability.

Frequently Asked Questions
What is the difference between total capacity and usable capacity?
Total capacity is the battery’s full storage, while usable capacity is the portion available for daily use after accounting for safety limits.
How long do solar batteries last?
Most systems offer around 10 years warranty and thousands of charge cycles, depending on usage and conditions.
Can I add a battery to an existing solar system?
Yes, but compatibility depends on your inverter type (hybrid vs. standard) and system configuration.
What is peak power output used for?
It determines how many appliances can run simultaneously, especially during outages.
Are batteries expandable?
Many modern systems are modular and allow additional capacity to be added over time.
