Tesla Powerwall 3

Tesla Powerwall 3 is the latest version of the UK’s most popular battery storage

The Tesla Powerwall 3 – an upgraded version of the Powerwall 2 – is now more powerful and flexible than ever before. It’s the go-to premium battery storage for 2024 if you want the best all-round product available.

What are the benefits of the Tesla Powerwall 3?

This third iteration of the Powerwall is packed full of features, making it ideal for home or business installations. Here are the highlights:

Capture surplus solar electricity – if you have solar panels, Powerwall 3 will automatically store excess solar for later use
A massive 13.5 kWh of storage capacity – the average house needs just 10 kWh of electricity per day
Power output rating of 11.04 kW – enough to power multiple electrical devices simultaneously
Emergency power in a power-cut – if the national grid goes down, you can still power your property via the Powerwall
Tesla Powerwall 3 now comes with an integrated solar inverter – save £100s if you are getting solar panels installed as well
Store cheap, off-peak electricity – top up your battery storage with low-cost electricity and discharge when grid rates are high

How does Tesla Powerwall 3 work?

Tesla has been perfecting the Powerwall since it first came out in 2015. This third version – Powerwall 3 – is incredibly versatile and can be installed in different ways, depending on your exact needs.

With solar panels

If you are getting solar panels and battery storage installed at the same time, the best way to connect the Powerwall is ‘DC-coupled’. This is how it works:

Your solar panels are connected to the inverter inside the Powerwall, meaning you don’t have to purchase a separate solar inverter.
When the sun shines on your solar panels – producing Direct Current (DC) electricity – the DC electricity either flows directly into your Powerwall battery and is stored for later use, or the DC electricity is converted by the Powerwall inverter into Alternating Current (AC) electricity for you to use at that moment.
Stored DC electricity inside the Powerwall 3 is converted into AC electricity, as and when it is needed by the property or business.
All the electrical flows and conversions are coordinated automatically by a separate box called the Tesla Gateway. The Gateway monitors electricity flowing into and out of the building, as well as which devices need power, and regulates Powerwall charging and discharging accordingly.

Without solar panels

Tesla Powerwall 3 can also be installed without solar panels via an ‘AC-coupled’ installation which allows you to:

Charge your Powerwall with cheap off-peak electricity. You need to sign up to a tariff with your energy supplier that has both a cheap rate (usually at night) and a normal day rate. For example, you could charge up at say 7.5p per kWh overnight and then discharge that cheap electricity into your property during the day when you would normally be paying around 28p per kWh.
A Powerwall 3 without solar panels still means you can benefit from whole-home emergency power in a power-cut. So if you live in an area of the UK where power-cuts are more frequent, a Powerwall can help you keep the lights on when your neighbours are in the dark.
Without solar panels, the Powerwall is only charged with AC electricity from the grid. That grid AC electricity is converted into DC electricity by the Powerwall’s built-in inverter and stored, and then converted back into AC electricity when needed by the property.

First class installation and support
We had 24 solar panels installed in a ground array, with a battery and EV charger. Everyone at Infinity was very professional, competent and friendly from start to finish. We are now pretty much ‘off grid’ during the summer!

How much is a Tesla Powerwall 3?

Cost per unit of storage is low

The Tesla Powerwall 3 UK price will vary considerably from installer to installer. The cost of the Powerwall 3 will also often depend on whether you are having it retrofitted to an existing solar panel system or installed alongside a new set of solar panels.

As it’s a brand new product, real-world pricing is still settling down. The current market price range for a Powerwall 3 is between about £8,000 and £11,000, fully installed and commissioned. There is no VAT to pay, as battery storage is exempt.

At Infinity, we offer the Powerwall for less than £8,000 – we go even lower if you have solar panels installed by us as well. Get in touch for an accurate price.

The Tesla Powerwall 3 cost may seem quite high, but actually it’s one of the cheapest storage units available when you consider the cost per kWh of storage. Tesla have managed to create the best battery product in the UK, at a very aggressive price per unit of storage.
