Eleven Energy has launched its residential sodium-ion storage system at The smarter E in Munich. The fully integrated platform combines sodium-optimized batteries, inverters, and AI energy management to improve safety, flexibility, and tariff-driven optimization.
Cambridge-based cleantech startup Eleven Energy has launched its new residential sodium-ion storage solution at the Smarter E event in Munich, Germany, this week.
The company said it has already deployed its systems in several hundred homes, supported by a nationwide installer network of more than 100 certified partners, marking one of the first large-scale residential sodium-ion field implementations in Europe.
“The opportunity for sodium-ion is strongest where storage is part of a complete energy system, not just a cell chemistry,” Yichen Shi, CEO and co-founder of Eleven Energy, told pv magazine. “For residential and commercial storage, we are designing around sodium from the battery module to the inverter, software and installer experience. Our aim is to make storage safer, more sustainable and practical for everyday solar and tariff optimisation.”
The new product consists of an integrated stack comprising dedicated sodium-ion battery modules, hybrid inverters engineered for sodium voltage characteristics, and an AI-driven energy management platform designed to optimize self-consumption, tariff arbitrage, and system longevity. Eleven Energy said this approach reflects a broader shift in stationary storage design: away from chemistry-agnostic “drop-in” batteries and toward co-engineered systems where hardware and software are tightly coupled.
