The Tesla Powerwall 3 has arrived, promising to revolutionise home energy storage in the UK. Here’s everything you need to know about this groundbreaking innovation.

Introducing the Tesla Powerwall 3: Features, Benefits, and More!
Now available for pre-order in the UK, from Tesla’s Premier Installers the Tesla Powerwall 3 marks a new era in home battery storage. As one of the earliest licensed installers in the UK, Stratford Energy is proud to bring this cutting-edge technology to your doorstep.
Customers across the Midlands have already experienced the benefits of Tesla’s battery storage solutions, harnessing excess solar power, charging electric vehicles, and enjoying reliable backup during power outages. To date this has been achieved through the initial Powerwall battery, and the Powerwall 2.
But why choose the Powerwall 3 over the Powerwall 2?
The Powerwall 3 takes this to the next level, offering advanced energy tariffs and enabling electricity trading with the grid.
What Makes Powerwall 3 Unique?
The major upgrade in the Powerwall 3 is its integrated solar inverter, enhancing efficiency by enabling direct solar integration (DC coupling). This means that electricity generated from solar panels is directly stored in the battery, with minimal conversion losses, boosting overall storage efficiency from 90% to an impressive 97.5%.

Key Features of the Powerwall 3
Integrated Solar Inverter
Efficiently converts solar energy into stored power, capturing more solar energy.
Modular System
Expandable to meet growing energy needs; up to four units can be stacked, with additional DC expansion packs for each.
Exceptional Value
Comes with a 10-year warranty, unlimited cycles, 80% energy retention after a decade, and 100% depth of discharge.
Improved Thermal Management
The redesigned system enhances performance and efficiency.
Looking for the Tesla Powerwall 3 specification?
The Powerwall 3 supports up to 20 kW DC of solar input and delivers 11.04 kW AC of continuous power per unit, with a storage capacity of 13.5 kWh. The system allows for quick installation, easy expansion, and seamless integration with any electrical service.
Additional Benefits of the Powerwall 3
Considering a Tesla Powerwall 3 installation? Here’s why it’s a smart choice. As a Powerwall owner, you’ll enjoy whole-home backup during outages and achieve energy independence by generating sustainable solar energy at home.
The Tesla app provides real-time monitoring and energy management, allowing you to optimize your system’s performance. Integrating your solar panel system with the Powerwall 3 is the ultimate way to manage your home’s energy efficiently.
Tesla continues to push the boundaries of energy innovation, and the Powerwall 3 is no exception. It’s designed to meet your home’s energy needs, offering more energy per unit with easy expansion options.
Equipped with an integrated hybrid inverter, it optimises energy use by sharing its inverter with the solar panels. No other home storage battery has the experience of more than ½ million installed units.
With an inverter rating of 11kW, the Powerwall 3 can support a sizable solar PV system, and its three MPPT inputs ensure
it meets most installation shading requirements. The Powerwall 3 doubles the power supply of its predecessor, providing twice the power during outages. Unfortunately, these are an increasingly regular occurrence and as announced in a recent UK national newspaper, “French-built nuclear reactor delays to put Britain at risk of blackouts” Telegraph 24.02.2024 are likely to increase.
One Powerwall 3 at 13.5kWh will be able keep the power on in a family house for 12 hours without rationing.
