Already have a Powerwall 2? You can now expand your energy storage with the latest Powerwall 3 technology while keeping the battery system you already own.
Powerwall 3 is now compatible with Powerwall 2, making it easier and more cost-effective for Australian homeowners to increase battery capacity, maximise solar energy usage, and gain greater energy independence.
At Solahart, our Tesla Certified Installers can help design and install the right battery solution to suit your home's current and future energy needs.
Expand Your Battery Storage Without Starting Over
With Powerwall 3 compatibility, existing Powerwall 2 owners can add a Powerwall 3 and Powerwall expansion units to their system, increasing storage capacity without replacing their current battery. This means:
- Better use of your solar energy
- Longer backup during outages
- Greater energy independence
- More flexibility as your energy needs grow
Whether you've added an electric vehicle, upgraded to electric appliances, or simply want greater energy security, expanding your existing Powerwall system can help you get more value from your solar investment.
Government Rebates and Incentives Available
Eligible homeowners may be able to reduce the upfront cost of their battery upgrade through the Australian Government's Cheaper Home Batteries Program.
This program may provide upfront discounts on eligible Powerwall 3 systems and expansion units, helping households accelerate their transition to cleaner, more affordable energy.
Our team can help you understand available incentives and determine whether your installation may qualify.
