Simple, High-Power Energy Management

The Tesla Powerwall 3 is more than just a battery; it acts as the main hub for your home’s electricity. By building the solar inverter directly into the unit, Tesla has created a system that is efficient and much quicker for our team to install.

Because it can provide a higher level of steady power than older models, the Powerwall 3 easily handles heavy-duty equipment like ducted air conditioning, pool pumps, and electric vehicle chargers—items that many other batteries struggle to run.

Whether you are installing a brand-new solar system or want to move toward energy independence, the Powerwall 3 has the capacity and smart technology to keep your Sydney home running day and night.

Benefits at a Glance

  • All-In-One Solar Inverter: The Powerwall 3 includes a built-in solar inverter that can manage up to six solar inputs. This combined design works more efficiently and makes your installation neater by removing the need for a separate inverter box on your wall.
  • Backup Power for Your Whole Home: When the grid goes down in Sydney, the Powerwall 3 keeps your home running. Its high power output means it can provide a seamless backup for your entire property, keeping large appliances operational so your daily routine is not interrupted.
  • 13.5kWh Energy Storage: Save your daytime solar energy in a high-capacity 13.5kWh lithium-ion battery. This lets you power your home through the night and helps you avoid buying expensive electricity from the grid during peak-rate hours.
  • Simple App Control: Use the Tesla app to check your solar production, battery level, and home energy use in real-time. You can easily adjust your settings to save power for backup during storm warnings or to help lower your electricity bills based on your specific tariff.
  • Durable and Weather-Ready: Built to last in local conditions, the Powerwall 3 is water-resistant and dust-proof (IP67). The “Storm Watch” feature automatically monitors the weather and charges your battery to full capacity if a storm is detected in the Sydney region.

Frequently Asked Questions

Can I add this to my existing solar panels?

In most cases, yes. Because the Powerwall 3 has its own built-in solar inverter, it can often replace your old one or work alongside your current setup. When we do your in-home assessment, we’ll check your current panels and wiring to make sure everything connects perfectly.

What happens if there is a big storm or a flood?

The Powerwall 3 is built for Sydney’s unpredictable weather. It is water-resistant and dust-proof, so it can be installed indoors or outdoors. It also has a clever feature called “Storm Watch”—if the Bureau of Meteorology issues a storm warning for our region, the battery automatically tops itself up from the grid so you have a full tank of power before the lights go out.

How long will the battery last during a power outage?

It depends on what you’re running, but for a typical Sydney home using lights, Wi-Fi, and a fridge, a single battery can often last well over a day. If you’re careful with your power use, you can stretch it even further. You can also use the Tesla app to set a “backup reserve,” ensuring you always have a certain amount of power saved just for emergencies.

How long is the warranty on the Tesla Powerwall 3 home battery?

The Tesla Powerwall 3 is covered by a 10-year Tesla warranty.

Are there any government rebates available for me?

There are currently several incentives that can help lower the cost. Between federal STC credits and specific NSW battery incentives, you could save thousands on the upfront price. When we provide your quote, we include all the eligible rebates for your specific Sydney address so you see the final, “out-of-pocket” cost.
