Eleven Energy is pioneering the UK’s first sodium-ion home battery system, designed in Cambridge and already powering homes across the country. Our integrated hybrid inverter and smart battery technology offer homeowners a safer, more sustainable alternative to lithium-ion, using abundant sodium materials with no reliance on scarce or toxic elements.

Built for the real world, our systems operate reliably from -20 °C to +55 °C, giving families peace of mind in all seasons. With easy solar integration, support for EV charging and home energy management, Eleven makes it simple to store clean energy and cut electricity bills.

As a UK company with UK-based technical support and a trusted installer network, we’re committed to making energy independence accessible to every household. Visit us to discover why the future of home energy storage is beyond lithium — go sodium.
