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

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.
