Eleven Energy Volta 4.5 kWh Sodium Ion Battery
Eleven Energy Volta 4.5 kWh Sodium Ion Battery is a next‑generation home energy storage module based on sodium‑ion chemistry rather than lithium. It is designed for grid‑connected solar PV systems and off‑peak tariff shifting, providing robust performance in cold climates and a more sustainable materials footprint.
Key Features
- 4.5 kWh usable capacity – a compact single module providing around 4.5 kWh of storage for solar self‑consumption, backup and load‑shifting.
- Sodium‑ion chemistry – uses abundant sodium instead of lithium, avoiding water‑intensive lithium brine extraction and critical metals such as cobalt and nickel.
- Excellent cold‑weather performance – maintains performance and charging capability at low temperatures, operating happily down to around -20°C where many lithium‑ion batteries suffer reduced output and charge rates.
- Modular, wall‑mountable design – slim enclosure suitable for mounting on a wall in a utility room, garage or plant area, and designed to be combined with additional modules for higher capacities (subject to inverter compatibility).
- High cycle life – sodium‑ion cells engineered for daily cycling, supporting long‑term use in solar and time‑of‑use applications.
- Lower environmental impact – sodium is widely available from sources such as seawater and soda ash, enabling more sustainable large‑scale battery production.
Technical Highlights
- Chemistry: Sodium‑ion (Na‑ion) cell technology.
- Nominal energy: 4.5 kWh per Volta module.
- Operating temperature: wide working range with reliable operation down to approximately -20°C, ideal for outdoor or unheated locations when installed in a suitable enclosure.
- Application: residential and small commercial energy storage for solar PV, peak‑shaving and backup supply.
- Installation: designed to integrate with compatible hybrid or AC‑coupled inverters; wall‑mountable for flexible placement.
Environmental & Sustainability Benefits
- Abundant raw materials – sodium can be sourced using established processes without the extreme water usage associated with some lithium extraction methods.
- No cobalt or nickel – avoids reliance on challenging supply chains and reduces toxicity and ethical concerns linked to some lithium‑ion chemistries.
- Lower life‑cycle impact – by sidestepping critical minerals and high‑water‑use extraction, Volta sodium batteries support more sustainable, scalable energy storage deployment.
Typical Applications
- Pairing with domestic solar PV to store daytime surplus and use it in the evening or overnight.
- Time‑of‑use optimisation, charging from cheaper off‑peak tariffs and discharging during peak rate periods.
- Installations in colder climates or outdoor battery locations where lithium‑ion performance would otherwise be compromised.
