Tesla Powerwall 3 Expansion Pack
Expand Your Tesla Powerwall 3 Storage in Hervey Bay
If you’re looking to boost the performance of your Tesla Powerwall 3, Fraser Coast Energy now offers the Powerwall 3 Expansion Pack — the ideal upgrade for homeowners across Hervey Bay, Maryborough, and the wider Fraser Coast region who want greater energy security and independence.
Perfect for homes with existing solar and a Powerwall 3 already installed, this expansion unit gives you more stored energy for evenings, high-usage periods, and unexpected outages.
What the Tesla Powerwall 3 Expansion Pack Does
The Powerwall 3 Expansion Pack is a battery-only module designed to seamlessly integrate with your current Powerwall 3 system. Because the main Powerwall 3 already contains the inverter, the expansion unit directly connects to it, allowing the system to operate as one larger, more capable battery.
Your solar panels charge both units during the day, and the combined storage powers your home when you need it most — during peak electricity times, cloudy weather, or grid interruptions.
With the Tesla app, Fraser Coast homeowners can track energy production and storage in real time, fine-tune settings, and maximise savings with smarter energy usage.
Why Choose the Tesla Powerwall 3 Expansion Pack?
1. More Storage Instantly
Adds 13.5 kWh of extra capacity to your existing Powerwall 3 for longer backup power and more usable solar.
2. Simple, Seamless Upgrade
Connects directly to your Powerwall 3 with no extra inverter required, keeping installation clean and efficient.
3. Rebate-Ready
Upcoming national battery incentives make expanding your home storage even more cost-effective.
4. Scalable for Any Home
Add up to three expansion units per Powerwall 3 to match growing energy needs — from EV charging to larger homes.
5. Greater Energy Independence
Store more solar for night-time use, avoid peak tariffs, and stay powered during outages across the Fraser Coast.
6. Cleaner, Sustainable Living
Use more of your own renewable energy and reduce your carbon footprint while improving home resilience.
