Key Features

  • A complete all-in-one solution

    Our Smart Batteries offer a complete all-in-one solution for you. This includes your National Grid application, grade-A inverter, and modular Smart Battery as well as free delivery and installation by our team of experts to provide you with a complete turnkey solution for energy independence.

  • Compatible with all solar PV systems

    Our Smart Batteries are compatible with all modern smart hybrid inverters and solar panels, giving you the flexibility to choose from any solar PV provider. Whichever you choose, our experienced installers will ensure a safe and reliable connection.

  • Modular design

    Our unique Smart Batteries have been specifically designed to be modular, allowing for a more tailor-made energy solution for customers based on their specific energy needs. The modular design means you can expand your energy storage easily and cheaply, future-proofing your energy storage.

  • Safe technology

    Composed of high quality lithium cells, our Smart Batteries have been designed to be safe to use in domestic and commercial premises. All products have undergone extensive safety testing, UKCA and CE certification. For more on our in-built safety features check out our product specification sheets.

  • 20+ years of use

    We only use the highest quality battery cells, meaning our batteries have an expected minimum lifespan of at least 20 years. This ensures maximum return on investment on your Smart Battery as well as long-term energy independence for you.

  • Versatile placement options

    Most ‘all-in-one’ battery systems weigh over 150kg. Most UK homes simply can’t take the weight. While our Powerpod and Powerpanel offer wall-mounted placement for smaller setups, our larger Powerplant unit stands alone, giving you the freedom to install it anywhere in the home.

  • Rather pay in full?

    No problem. If subscription's not for you, you can buy any of our batteries outright, with free installation.
