The Tesla Powerwall 3 has arrived, and it’s bringing serious upgrades for anyone looking to take control of their energy use. With over double the previous power output (now 11.4kw), a built-in inverter, and smart energy management, this battery is designed to help homeowners maximise their solar power, save money, and stay powered up—even during outages.

If you've been thinking about adding a battery to your solar system, the Powerwall 3 is a game-changer for homes with bigger power loads. With new Government rebates, money for participating in Virtual Power Plants and the ability to store solar energy produced during the day for peak load times PLUS stay powered up even if the grid goes down, now is a great time to think about investing in a Powerwall 3

What’s New in Powerwall 3?

Tesla has made some major improvements with this model, making it more powerful, more efficient, and easier to integrate into your solar setup. The Powerwall 2 was already an impressive piece of technology but the Powerwall 3 steps things up a notch. Here’s what sets it apart:

✅ Higher Power Output

One of the biggest upgrades is the 11.5kW continuous power output—more than double the Powerwall 2’s 5kW. This means you can potentially run multiple high-demand appliances at the same time, like your air conditioner, pool pump, dishwasher etc, without worrying about overload.

✅ Built-in Solar Inverter

For the first time, Tesla has integrated a solar inverter directly into the Powerwall 3. This means your solar panels can connect straight to the battery, cutting down on additional components and making the whole system both more efficient and more aesthetically pleasing.

✅ More Energy in a Compact Design

While the storage capacity remains at 13.5kWh, Tesla has improved the energy density, meaning the battery takes up less space while still packing the same punch and gives enough room for the integration of the inverter without really changing the external footprint.

✅ Scalable for Larger Homes

If one Powerwall isn’t enough, you can install up to four Powerwall 3 units in parallel, giving you up to 54kWh of storage and 40kW of inverter capacity. This makes it ideal for larger homes, businesses, or those who want total energy independence.

Store Solar Energy & Use It at Night—Maximise Your Savings

If you already have solar panels, you know how frustrating it can be when your system is sending excess energy back to the grid for a fraction of what you pay to buy it back later.

That’s where the Powerwall 3 makes a big difference. Instead of exporting your surplus solar power to the grid for cents on the dollar, you can store it in your battery and use it when you actually need it—at night, during peak rate times, or on cloudy days.

💡 Less reliance on the grid = more money in your pocket.

Tesla’s Powerwall 3 intelligently manages energy flow, meaning it knows when to store energy, when to use it, and how to maximise your savings based on your household’s energy habits.

Stay Powered During Outages—Even in Storm Season

The Powerwall 3 is now so smart, it queries the weather and prepares for seamless backup power during storm induced blackouts. If the grid goes down due to storms, high demand, or maintenance, the Powerwall 3 kicks in instantly, keeping your home running without missing a beat.

⚡ No more sitting in the dark waiting for the power to come back.

⚡ Your fridge, lights, WiFi, and essential appliances stay on even when the grid is down.

⚡ The Powerwall recharges from your solar panels, meaning if the outage lasts a while, you’re still covered.

Power outages are inconvenient at best and life threatening for people with powered supports. With outages becoming more common—especially during storm season—having a battery backup is one of the best ways to protect your home and keep life running as usual.

Get Paid for Your Stored Energy with Tesla’s Virtual Power Plant

Another way the Powerwall 3 can help save you money is through Tesla’s Virtual Power Plant (VPP) program.

A VPP is a network of homes with Powerwalls that work together to supply energy back to the grid when demand is high. When you sign up, your battery automatically shares a small amount of excess stored energy when needed, and in return, you get paid through energy credits or rebates.

This means that instead of just using your battery to power your own home, you can help stabilise the grid and earn money back while you’re at it.

Who Is the Powerwall 3 For?

This battery is ideal for:

✔️ Homeowners who want whole-home backup – With its higher power output, it can keep your entire home running smoothly during blackouts.

✔️ Those looking to reduce electricity bills – Store your excess solar power and use it at night instead of paying high peak rates which are getting higher every year.

✔️ Future-proofing your home – The integrated inverter and scalability ensure your system can grow with you, whether that means adding more solar panels, an EV, or increasing energy usage over time.

✔️ Anyone wanting to break free from the grid – With solar + battery storage, you can generate, store, and use your own energy—giving you full control over your power.

How Much Does It Cost?

With government rebates of up to $2,500 now available in NSW, adding a Tesla Powerwall 3 is a very compelling option right now - particularly for seniors with fixed income wishing to protect themselves against rising costs over time for energy. When you do the math, calculate your savings with your solar + battery storage and you can see how it will pay for itself faster than ever. Add in the options for Virtual Power Plant earnings and the long-term savings far outweigh the upfront cost for a lot of use cases.
