Expand your home energy future: Tesla Powerwall 3 Expansion Pack now at Jet Solar

July 15, 2025

Big news for energy-savvy homeowners and businesses across South East Victoria and Melbourne’s inner suburbs: Jet Solar is proud to offer the brand-new Tesla Powerwall 3 Expansion Pack - your gateway to even greater energy independence, savings, and backup power.

As one of only ~40 Tesla Premium Certified Installers in Australia, Jet Solar is here to help you maximise your investment in solar and battery technology – with expert installation, local knowledge, and access to rebates like Victoria’s Cheaper Home Batteries Program.

Why expand your Tesla Powerwall 3 system?

Already installed a Tesla Powerwall 3? Good on you! But here’s the exciting part: with the Powerwall 3 Expansion Pack, you can easily scale your system to meet growing energy needs, without needing extra inverters or complex redesigns.

Each Expansion Pack adds:

  • 13.5 kWh of extra battery storage
  • Seamless connection to your existing Powerwall 3 (up to 3 expansions per unit)
  • Smart control via the Tesla mobile app
  • Heavy-duty performance, even supporting large home loads (up to 185 amps locked rotor current)

With modular floor or wall-mounted design, these units are ready for both indoor and outdoor setups, designed to thrive in Melbourne’s variable climate (-20°C to 50°C, IP67-rated). That means whether you’re in Berwick, Frankston, Dandenong, or Brighton, Jet Solar has you covered.

How it works: More power, less stress

The Powerwall 3 system already combines a powerful 13.5 kWh battery with an integrated inverter, managing up to 20 kW DC solar input and 11.04 kW AC continuous output. But with the Expansion Pack:

  • You scale your energy system affordably without adding more inverters.
  • You extend your backup power duration, essential during blackouts or peak demand.
  • You boost your savings by storing more solar for night-time or cloudy days.
  • You future-proof your home or business, accommodating EV charging, home extensions, or added appliances.

Full specs at a glance:

  • Model Number: 1807000-xx-y
  • Nominal Battery Energy: 13.5 kWh
  • Operating Temp: -20°C to 50°C
  • Mounting: Floor or wall, stack up to 3 expansions
  • Warranty: 10 years
