Stock is expected to become more limited closer to the deadline, so we recommend getting in early.

What this means for you

If you’ve been thinking about increasing your battery capacity, now is the ideal time to act.

Benefits of expanding your system

  • Increase your home’s energy storage
  • Improve backup capability
  • Maximise solar self-consumption
  • Support growing energy needs (EVs, appliances, pool equipment, and more)
  • Avoid missing out after the 2026 cut-off date

Common questions

Do I need to expand before the deadline?
If you think you may want more storage in the future, expanding before 31 December 2026 helps ensure you don’t miss out while modules are still available.
How do I know what expansion size I need?
We can review your current usage, solar production, and future plans (like EV charging or additional appliances) and recommend an expansion option that suits your home.
Are rebates guaranteed?
Rebates depend on eligibility criteria and program availability. We’ll help check what may apply to your situation at the time of assessment.
Reminder: Battery expansions are only available until 31 December 2026 or while stocks last.
