About the Tesla Powerwall 3

The new Tesla Powerwall 3 revolutionises the battery storage industry with game changing features and technology making saving and earning money, easy for those using them.

Tesla have upgraded the On-Grid power to 11.5 kW continuous, which is more than double the amount of the Tesla Powerwall 2.

You can ‘Earn by Selling’ where you can send energy back to the grid when the demand is high and get paid by Tesla. This is their Virtual Power Plant initiative to help stabilise the grid with clean energy.

Avoid power outages with a Powerwall 3. When the grid goes down, you can be safe in the knowledge that you will have your battery storage solution to keep you with power until the grid is restored.

The Powerwall 3 works with and without solar panels. Get more form your panels while you are out of your home by storing unused energy to the Tesla Powerwall 3. Alternatively, you can charge the battery at night using a cheaper tariff from the grid to use when the price per kWh is higher.

With AR Power, you can get a Tesla Powerwall 3 installed and ready for use quickly and easily. We are approved by the manufacturer and have extensive experience installing the Tesla Powerwall 2.

Our fully qualified installation team covers the whole of the North East, including Durham, Gateshead, Newcastle, South Shields, Sunderland, and Washington. So, wherever you’re based, you can get the benefits of Tesla Powerwall 3 batteries for your home.

Tesla Powerwall 3 Cost Overview

The general assumption when a new product comes to market is that the cost is going to be high, then reduced over time as R&D costs are recovered from sales. However this is not the case with the new Tesla Powerwall 3.

In fact, the cost of the new Powerwall 3 is not too different to the cost of it’s popular predecessor, the Tesla Powerwall 2.

The price Tesla advertise is not the price you pay, that is just the cost of the unit itself. There are some additional costs such as the DNO application cost, this is where we need to check with your local Network Operator to make sure you the grid will allow for the Powerwall. Sometimes they charge us, sometimes they don’t. If we do not get charged, we will refund this to you on your final invoice.

We also need to include the cost of labour to install the Tesla Powerwall 3. One of our highly trained and highly skilled Tesla certified installers will ensure your Powerwall 3 battery is installed safely. Our installation team take pride in their work so you can be assured the installation will be very tidy.

We will carry out a site survey before installation and let you know if there are going to be any additional costs to installing your Tesla Powerwall 3 battery. If you have thich stone walls to drill through, this may add to the cost, and the location of your meter and the location of where you want your Powerwall installing will also determine the overall cost of your installation.

Tesla Powerwall FAQs

Using a Tesla Powerwall in conjunction with a solar installation can reduce your reliance on fossil fuels and limit your use of energy from the grid. It can also allow you to power an electric vehicle, which will reduce your use of gas or petrol-powered transport. With the right solar panel system and Tesla Powerwall units, it is possible to meet your home’s electricity demand without relying on traditional energy sources during the spring and summer months.

Tesla Powerwalls can be used without solar panels. Most energy companies will give you a tariff where you pay a lower rate for energy at night, allowing you to charge your Tesla Powerwall with cheaper energy to use during the day when prices are higher.

Small businesses can make the most of their solar panels by installing Tesla Powerwalls. For larger businesses, we can create custom battery storage solutions to help you harness the unused power output from your large solar array.

The Tesla Powerwall 2 is the current battery offered in the UK, but the Tesla Powerwall 3 is due to be released in 2024.

This depends on the types of appliances you use, your home’s energy source, how many solar panels you have if you’re using solar generation and the size of your household. Generally, a Tesla Powerwall can keep your property self-sufficient throughout Spring and Autumn if used in conjunction with a suitable-sized solar PV array. For larger households that use more electricity, multiple Powerwalls can be installed to meet your energy needs.

Tesla batteries are specifically designed for power outages and will start powering your home should your mains power fail, providing you have enough charge in your battery. They can power the average home with several appliances running for hours, meaning that power outages won’t affect your life. With a Tesla Powerwall, you’ll always have backup power, provided there is enough stored energy in the unit.



Tesla Powerwalls are an ideal way to reduce the cost of your energy bills, whether you have an existing solar PV system or not. Stored energy generated from your solar panels can be used at night when there’s no sunlight to charge your solar panels, meaning you can use renewable energy for longer. You can also store electricity from the grid overnight when the price per kWh is lower, then use it during the day when the price per kWh is higher to cut costs. Your Tesla Powerwall can also reduce costs associated with power cuts by providing power continuously to appliances like freezers or heating systems.

It is possible to install multiple Tesla Powerwall batteries in your home. How many you can have will depend on what the Distribution Network Operator (DNO) allows and the amount of space you have. You can have up to 3 Powerwalls per phase, and if you have a larger home with 2 or 3 phases, you will also need a Tesla Powerwall Gateway and battery for each phase. Multiple Tesla Powerwall batteries can be stored on top of each other or be wall-mounted in a row, depending on your space and home layout. We can discuss your options further and provide bespoke guidance, so contact us for more information.

The Tesla Powerwall comes with a 10-year warranty, and its lifespan will depend on how much you use your battery, but most customers report that it can last 20 years or more.

The Powerwall Gateway is the control system for your Powerwall battery. It works with your energy supplier, be it from your solar panels or the National Grid, to control the energy going to your battery. You need 1 Gateway per phase, and most residential properties have 1 phase. If you have more than 1 phase, you will need a Gateway and Tesla Pwoerwall for each phase to balance the system.

John Irving – Google


Couldn’t recommend ARP enough. After installing our solar panels, they have kindly sourced and installed our solar battery. Despite being an old house and a tricky installation , they have made the whole process effortless. Thank you again!

We chose AR Power to install our Powerwall 2 battery and were not disappointed. From the moment of placing the order they took care of everything, right through to completion of the project. They were always happy to explain and update us on progress or explain any technical queries we had. Their installation engineers were competent, polite and tidy. We have ended up with a very neat and tidy job giving us exactly what we set out to achieve. We wouldn’t hesitate to use them again (but have now sadly run out of space!!!) and have no hesitation in recommending them to others.

I’ve been a returning customer to ARPower. I’ve used them for all my solar, battery and so on. I’ve recently just had a Tesla battery fit, and I couldn’t be happier. Strongly recommend ARPower.
