Tesla Powerwall 2 Installations

 Tesla Premium Installer

In 2016, Tesla selected 50 businesses in the UK to be the first installers of their newly introduced Powerwall Battery System. Due to the quality of our reputation, Steve Duckworth Electrical, despite being a tiny 2 person team at the time, was one of the 50. Since then, we have won multiple Tesla ‘Customer Service Excellence’ awards for repeatedly receiving the highest number of top rated feedback from customers throughout the entirety of the UK for our installations.

As of 2024, we have been selected by Tesla as one of a very select few TESLA CERTIFIED PREMIUM INSTALLERS for Powerwall Batteries throughout the UK.
At Steve Duckworth Electrical, we pride ourselves on customer satisfaction and quality of installation, backed up by Tesla themselves. 

What is a Tesla Powerwall?

A Tesla Powerwall is essentially a battery pack for your house. It allows you to store excess solar energy created during the day, for use at night or on cloudy days. It can also be beneficial if you do not have solar panels, but are on cheap rate electricity, as it can self charge in the early hours of the morning, when some electricity rate tariffs are at their lowest, meaning you get to enjoy cheap rate electricity whenever you need it. Tesla Powerwalls can also be beneficial during power cuts, as they can seamlessly switch into backup mode.

What are the benefits of the Tesla Powerwall?

Increased Self-Consumption

Powerwall can store surplus solar energy during daylight hours and uses that energy when the PV system is generating below your consumption. Powerwall can store 13.5kW and will charge and discharge at 5kW. 5kW could run both a washing machine and a dryer at the same time without the need to rely on the grid.

Time Based Control

Powerwalls can charge during low rate electricity tariff periods (Economy 7, 10 or Smart Meter Tariffs) and discharge during more expensive rate periods. This facility means you don’t have to have Solar PV if your property isn't suitable, but can still reap the benefits of cheaper electricity.

Backup

The Tesla Backup Gateway now allows the home owner to keep the electricity on during a power cut. This facility also lets the Solar PV system charge the Powerwall with any surplus generation, thus, it’s possible to be “Off Grid” for several days.

Storm Watch

Powerwall now automatically charges to 100% when a named Storm is heading to the UK’s shores, this facility makes sure the Powerwall is ready to power your home should there be a power cut.

Tesla App - Control & Monitor From Your Phone 

The Powerwall 2 comes with an App for your smart phone or tablet. The App allows you to see, in real time, the state of charge, self consumption and Solar PV generation. It is also possible to see your home’s historic information on generation, consumption, self consumption and grid usage/export. The App is also where you will setup your system to charge and discharge at specified times of the day, using the Time-Based Control and Utility Rate Plan. The Backup Reserve is also set using the app, allowing you to alter the amount of energy kept in the Powerwall - keeping more if your property is susceptible to power cuts, or adjusting the amount up if there is a planned power off by your DNO.

How Do Tesla Powerwalls Work?

The Powerwall 2 is coupled directly to an AC supply. This allows the battery to charge from the excess Solar Power or from the Off Peak Grid. It also enables the Tesla Powerwall 2 to be retro fitted to any existing electrical installation with or without  a Solar PV system. We can provide solutions for most situations, so please drop us a line or ring to discuss your requirements.

Why Choose A Tesla Powerwall?

The aim of installing a battery system is to use as much of the energy produced by your home's Solar PV system or cheap rate electricity as possible. As you can see by the graph, our featured client is maximising their system so that they still have energy stored in their battery in the morning. The only energy bought is where you can see the peaks in red. This graph shows the energy usage for this client on the 4th July 2016.

A Tesla Powerwall is a rechargeable lithium-ion battery storage system designed for residential and commercial use. The Powerwall stores electricity generated from renewable sources like solar panels or from the grid during off-peak hours, allowing users to access stored energy during times of high demand, power outages, or when electricity prices are high. It can be used for various purposes, including providing backup power, reducing reliance on the grid, and optimising energy consumption. The Powerwall is known for its sleek design, advanced technology, and integration with Tesla's energy ecosystem.

Tesla Powerwalls can be installed seamlessly, to your walls or ground, indoors or outdoors. Depending on the size of your property, between 1 and 10 Tesla Powerwalls can be linked together for domestic or commercial use.

As more and more people make the switch to electric over fossil fuels to power their homes and vehicles, regular power cuts with the UK’s aging power grid will only become ever more prevalent as the years go by. Even for homes with Solar, this cuts out and ceases to produce and utilise green energy. With a Tesla Powerwall 2 system, your battery takes over if your backup gateway detects a power outage, increasing your security and providing you with piece of mind that your home can continue running during a power outage.

Tesla Powerwalls are designed with safety as a top priority. They undergo rigorous testing to ensure they meet stringent safety standards and regulations. The batteries are equipped with built-in safety features, such as thermal regulation systems and multiple layers of protection to prevent overheating, short circuits, or other potential hazards. Additionally, Tesla provides comprehensive installation guidelines and recommendations to ensure safe and reliable operation. Tesla Powerwalls are engineered to minimise potential safety concerns and are considered safe for residential and commercial use when installed and operated according to manufacturer specifications.

No, having a solar panel system is not a requirement for installing a Tesla Powerwall. While the Powerwall is commonly used alongside solar panels to store excess energy generated during the day for use during periods of low sunlight or at night, it can also be installed as a standalone energy storage solution. If you have variable electricity rates or experience frequent power outages, a Powerwall can still provide benefits by storing energy from the grid during off-peak times or serving as a backup power source.

Throughout the daylight hours, your Solar PV system efficiently caters to the energy demands within your property, while any surplus energy is seamlessly directed towards charging your Tesla battery. After sunset, your home seamlessly transitions to drawing electricity from the stored energy in your battery, ensuring a continuous supply of clean and sustainable energy around the clock. The Tesla Powerwall 2 offers the additional flexibility of charging from the grid during off-peak hours when electricity rates are lower. With its 13.5kWh of usable storage capacity housed within a lithium-ion battery pack, it has the capability to power an average two-bedroom home for an entire day.

One thing we’ve noticed from other installers websites and from customers who’ve asked for lots of quotes from different installers and then chosen us, is that transparency does not seem to be at the forefront of their agendas. At Steve Duckworth Electrical, we don’t advertise one set price on our website, this is because depending on inflation, available government grants at the time of enquiry, and your needs as a customer, the prices constantly fluctuate, and we strive to stay as competitive and reasonably priced as possible throughout any fluctuations.
Many other websites advertise a cheap install price, which hikes up once they have your interest. As a premium installer for Tesla, and as one of very few who’ve repeatedly won Tesla customer service excellence award, we take pride in providing a single, all-in quote, and delivering top quality service. Just get in touch with one of our team via phone or email and you’ll be provided with a quote asap. 

Steve Duckworth Electrical can assist you in determining the optimal number of Tesla Powerwalls required for your specific needs. By providing details on your energy consumption, backup power requirements, and goals for energy independence, our team can calculate the ideal number of Powerwalls necessary to meet your needs effectively. With our expertise, we can evaluate factors such as daily energy usage, backup power duration, integration with solar panels, and available budget and space to ensure a tailored solution that aligns with your preferences and circumstances. Let us handle the calculations and provide you with personalised recommendations to make the process easier for you.
