The Complete Tesla Powerwall 3 Review

Tesla is one of the most innovative brands around, and the Powerwall series of batteries lets users store excess energy. The Tesla Powerwall 3, released in 2024, is the new kid on the block.

It’s bigger and better than its predecessors and comes with the latest technology. Is the Powerwall 3 right for your property? Find out here as we put the battery through its paces. 

What are solar panel batteries?

Solar panels are an innovative way to reduce your reliance on the electricity grid and live greener. These panels rely on energy from the sun, which is fine for homes in countries with year-long sunshine. 

The UK, though? Well, our lovely country isn’t known for its abundant sunshine. So, how can we turn solar panels into a financially viable solution? By using batteries. 

Solar batteries are a great way to store excess energy and power your home during those cloudy days. You can also make money by selling your excess energy through the Smart Export Guarantee (SEG). 

You’ll find batteries at all price points and capacities, including the Powerwall 3. 

What is the Tesla Powerwall 3?

Tesla’s Powerwall series was introduced in 2015, promising homes and businesses a reliable energy storage solution. 

Powerwalls 1 and 2 were fine, but Tesla’s Powerwall + became a game changer for the industry thanks to its combined solar inverter. 

The Powerwall 3 says goodbye to its predecessors’ weaknesses and uses new features that align with the ever-evolving needs of renewable energy users. 

When combined with solar panels, this battery offers consistent electricity, even on those colder and darker days. 

Features and specs:

• Energy Capacity: The Powerwall 3 gives you 13.5 kWh of usable capacity, which is the same as the Powerwall 2. BUT, you’ll also get a 7.5% increase in efficiency, which is pretty impressive. The capacity can power an average home for around 24 hours.
• Power Output: A battery’s output affects whether it can power appliances and equipment. With an 11.5 kW continuous power output on average, the battery will power high-consumption appliances and equipment without breaking a sweat. 
• Integrated Inverter: Another standout feature is the integrated inverter, which simplifies installation. You won’t need to worry about buying a separate inverter; there’s less chance of failure with an all-in-one solution. 
• Modular Design: The Powerwall 3 has a unique modular design, enabling the combination of multiple units. This design is more flexible, and a stackable battery can be beneficial for larger homes or businesses.
• Durability: The UK is no stranger to rain and strong winds, so you’ll want a solar panel battery that can hold its own. The Powerwall 3 has a water-resistant casing and IP67 rating, which protects it from water and dust exposure. 
• Backup Functionality: What’s the point of having a battery without backup? With Powerwall 3, you’ll never have to worry about a power cut again. It will power your appliances and equipment, but there’s also an option to configure the system and the most important appliances.
• Software and Connectivity: Tesla’s software integration allows for real-time monitoring and control through the Tesla app. You can track energy usage, adjust the settings, and monitor solar production through one convenient dashboard. 

How much will the Tesla Powerwall 3 set me back?

As the newest battery in Tesla’s range, the Powerwall 3 will cost between £6,300 and £10,000, depending on whether you require add-ons and extra solar panels. You’ll also need to factor in any installation costs. 

While the Powerwall 3 is one of the higher-end batteries, it delivers modern features and won’t let you down. You can also take advantage of the 0% VAT initiative, which will continue up to 2027. 

Environmental considerations 

When compared to fossil fuels, solar energy is a huge step forward in reducing our carbon emissions and preserving vital resources. The Powerwall 3 is integral to efficiency, as it stores excess energy for later usage. 

With their impressive output and capacity, Powerwall 3 batteries are also versatile. They can charge compatible vehicles and don’t even need solar panels to work. Some households connect them as a backup power source should they lose access to the grid. 

Tesla also takes responsibility for the environment, ensuring battery components undergo recycling processes and offering customers initiatives. 

Tesla Powerwall 3 pros 

If you’re looking for a battery that will cut your energy bills and help you achieve grid independence, the Powerwall 3 might be the answer to your prayers. Here are its pros: investment. 

• More Capacity and Power: The Powerwall 3 is Tesla’s most advanced battery. Its heightened capacity and output means you can have peace of mind in outages.
• Efficiency: Energy efficiency is vital for a greener planet, and the 7.5% increase on the Powerwall 2 is a welcome improvement. Higher efficiency levels mean your home or business can use more energy.  
• Solar Panel Integration: The Powerwall 3 works with solar panels, letting you store excess energy and use it when needed. You can also earn some extra money by sending your excess energy back to the grid. 
• Convenient Control: Monitor and control your Powerwall 3 system remotely through the Tesla app. It gives you real-time information about energy usage and performance.
• Long-term Savings: Solar panels offer long-term cost benefits, but adding a battery means you can break even quickly and achieve energy independence.
• Property Value: Installing a Powerwall 3 can potentially increase your home’s value, especially if the area is prone to power cuts.

Potential dealbreakers: 

It’s Expensive: Solar panel batteries are an investment, but the Powerwall 3 is what we’d call a premium battery. Its price tag might mean it’s out of reach, but cheaper batteries lack advanced features.

Limited Output: The Powerwall 3 offers an impressive power output, but larger homes and businesses might have to prioritise which appliances and equipment are most important during an outage.

Warranty Issues: While the Powerwall 3 has a 10-year warranty, it must be connected to the internet without disruptions. Tesla might reduce your warranty by up to 60%, meaning you could have expensive repairs or replacements within four years.

Installation: You’ll need to contact a professional installation service when you buy a Powerwall 3. Installing it yourself or failing to use a certified professional voids your warranty. Budgeting for the installation costs can be challenging. 

Is the Tesla Powerwall 3 worth it?

With its impressive features and upgrades, the Tesla Powerwall 3 is hard to overlook, but is it the right choice for you? 

Sure, it’s a bit pricey, but it’s important to factor in the long-term savings and environmental benefits.  

Are there cheaper batteries? Absolutely—but they’ll struggle to match the Powerwall 3’s output and capacity. 

It comes down to personal choice and whether you’re willing to put your money where Tesla’s mouth is.
