Tesla Powerwall 3 Expansion Pack in Wagga Wagga

The Powerwall 3 Expansion Pack is now available in Australia and SolarWise Wagga is bringing it to homes across Wagga Wagga and the Riverina. This upgrade lets existing Powerwall 3 owners add more storage capacity easily and cost-effectively, making it a strong choice for anyone looking to improve energy independence and protect their home from rising power costs.

How the Powerwall 3 Expansion Pack Works

The Expansion Pack is a battery-only unit designed to connect directly to your current Powerwall 3. Because it doesn’t contain its own inverter, it stays compact and affordable while integrating seamlessly with your existing system.

Your main Powerwall 3 manages the charging and discharging of the Expansion Pack, allowing you to:

• Store more of your daytime solar

• Reduce reliance on the grid during expensive evening hours

• Extend backup power during outages

• Monitor and control everything through the Powerwall app

The Powerwall 3 Expansion Pack adds an extra 13.5 kWh of storage to your existing Powerwall 3 setup, giving Wagga Wagga homeowners more flexibility, more backup power and more value from every unit of solar generated. Here’s why it’s such a strong upgrade:

More Storage Without Extra Hardware

Increase your battery capacity by 13.5 kWh without installing another inverter. It’s a simple, efficient way to boost total system capability.

Seamless System Integration

The Expansion Pack connects directly to your existing Powerwall 3. The main unit manages everything automatically, making installation straightforward and operation smooth.

Rebate Eligible Under the Federal Program

The Federal Battery Rebate provides significant support for eligible households, helping reduce the upfront cost of adding more storage. The Expansion Pack qualifies under this scheme.

Scalable for Growing Energy Needs

Add up to three Expansion Packs to a single Powerwall 3 system. That’s up to 40.5 kWh of additional capacity — perfect for homes with high consumption, EV charging or future upgrades in mind.

Greater Energy Independence

Store more of your solar during the day, use it at night, and extend your backup protection during outages. It’s a reliable way to cut grid reliance and stabilise your home’s energy supply.

More stored solar means fewer grid imports, lower emissions and a stronger step toward sustainable energy use across the Riverina.
