Tesla Powerwall 3 Expansion Pack in Canberra – Installed by SolarHub
Tesla Powerwall 3 Expansion Pack in Canberra
If you’re ready to increase your home’s battery capacity, the Tesla Powerwall 3 Expansion Pack is now available through SolarHub across Canberra and the South Coast. This upgrade allows households to store significantly more solar power, reduce evening and peak-time grid reliance, and improve blackout resilience—without needing to install another full Powerwall system.
What Does the Powerwall 3 Expansion Pack Do?
The Expansion Pack is specifically engineered for homes that already have a Tesla Powerwall 3. Rather than purchasing a second battery with duplicate electronics, the Expansion Pack provides additional storage capacity only. This makes upgrading more affordable and more efficient, while delivering:
-
More usable stored energy at night
-
Stronger backup during outages
-
Better support for EV charging and electric appliances
-
Improved solar self-consumption (use more of the power you generate)
Why Upgrade with a Tesla Powerwall 3 Expansion Pack in Canberra
The Powerwall 3 Expansion Pack allows you to increase the energy storage of your existing Powerwall 3 system by an additional 13.5kWh, giving you more control over when and how your home uses electricity. It’s ideal for homes and businesses across Canberra, Queanbeyan, Batemans Bay, Moruya, Bega and the entire South Coast that want to reduce energy costs and strengthen backup protection.
Here’s why more locals are choosing to expand instead of replacing or duplicating systems:
- More Storage for a Lower Upgrade Cost: Instead of buying another full Powerwall with all the electronics included, the Expansion Pack adds storage only. This makes it much more cost-effective, while still delivering the same high performance and reliability Tesla is known for.
- Designed to Integrate Smoothly: The Expansion Pack connects directly to your existing Powerwall 3, using the original unit as the control hub. No complex reconfiguration, no new monitoring system — just more stored solar ready to use when you need it.
- Federal Battery Rebate Support: With the upcoming Cheaper Home Batteries Program, eligible homes may receive a government rebate toward battery installation or expansion. This could make adding extra storage far more affordable for households across the ACT and the South Coast.
- Built to Grow With You: Whether you’re planning to go all-electric, charge an EV at home, or simply want better blackout resilience, your storage can be scaled over time. A Powerwall 3 system can support up to three expansion packs, offering up to 40.5kWh of extra usable storage for larger energy needs.
