Galvani Stackable Sodium-ion Battery Starts Rolling Out

10/04/2026

The long-awaited Galvani stackable sodium batteries have officially started shipping to customers across the UK.

This is a major milestone for Eleven Energy to bring a truly modular sodium-ion solution to market — and it’s fantastic to see these systems now being installed in homes.

Built for Flexibility and Scale

The Galvani system has been designed with installers in mind:

  • Modular, stackable design for flexible system sizing
  • Clean, compact installation
  • Seamless integration with Eleven Energy hybrid inverters
  • Designed specifically for UK homes and installation standards

Each stack can be tailored to the property, making it easier to meet a wide range of customer requirements without overcomplicating installation.

Strong Demand from Day One

Demand for Galvani has been exceptional. Installers and distributors have responded incredibly positively to:

  • The simplicity of installation
  • The scalability of the system
  • The advantages of sodium-ion chemistry, particularly around sustainability and cold-weather performance

Send us your install photos so we can celebrate your work and share the excitement with the community.

If you’re interested in installing Galvani systems and haven’t yet completed training, we encourage you to join one of our regular sessions.
