Home Batteries: Could Sodium Be More Popular Than Lithium Soon? – Our Conversation with Gary Does Solar
We’re proud to share a brand-new, in-depth installation and review video from eFixx, showcasing the Eleven Energy sodium-ion home battery system in a real UK household.
This is the first time many homeowners — and even installers — will have seen sodium-ion technology deployed in a complete solar + battery setup.
🔍 What’s inside the review?
The eFixx team take viewers through the entire installation journey, including:
- Cleaning and preparing the roof
- Fitting and inspecting existing solar panels
- Running new DC and AC cabling
- Installing the Eleven 6 kW hybrid inverter
- Mounting and wiring two 4.5 kWh sodium-ion battery modules
- Completing commissioning through the Eleven installer app
- Connecting the system to the cloud and monitoring consumption
The video also compares sodium-ion to lithium-ion, highlighting the environmental and practical advantages of using abundant salt-based materials instead of scarce or high-impact metals.
🌍 Why sodium-ion?
As eFixx explain, sodium-ion batteries offer:
- Safer operation and greater thermal stability
- Sustainability with no lithium or cobalt
- Abundant materials from seawater and salt mines
- Reliable performance from –20°C to 55°C
- Deep discharge capability and long cycle life
These benefits make sodium-ion one of the most exciting battery technologies for future home energy storage.
📱 Living with the system
The video includes real-world winter data showing:
- How solar production charges the battery
- How the system avoids exporting energy unnecessarily
- How little grid power was needed on a cold December day
- How the app displays solar, consumption, tariff and grid information in a friendly, intuitive layout
The Eleven installer app and homeowner app both receive strong praise for usability and clarity.
⚡ A huge thank you
We’re grateful to the eFixx team, Joju Solar and everyone involved in the installation and review.
Their detailed, honest assessment helps more homeowners and installers understand why sodium-ion is becoming a breakthrough technology for the UK.
