Sodium-ion home batteries in the UK
Sodium-ion home storage has reached the UK, but choice is still narrow. Eleven Energy says its Galvani system began shipping in April 2026; other products may be listed yet unavailable or still in field testing.
Available does not mean interchangeable
Galvani uses 4.5 kWh modules and the maker lists charging from -20°C. It is part of an Eleven Energy inverter ecosystem. Confirm the exact compatible inverter, usable capacity, backup behaviour and installer support before treating it as an alternative to a mainstream LFP system.
Spotting a premature listing
A product page, price or “notify me” button is not proof of stock. Beyond Batteries’ Sodi-Home page, for example, states that the product is sold out and undergoing extensive field testing. Our tracker classifies it as not on sale.
Before signing a quote
Ask for the datasheet, installation manual, written warranty, certification, DNO process, monitoring terms and end-of-life route. Check who pays labour if a module fails and whether the inverter can run without cloud access. Compare against a well-supported LFP quote, not against sodium marketing alone.
Questions answered
Can I buy one now?
Yes, from a small number of specialist UK suppliers and installer networks. Verify live stock and installation coverage.
Should I wait for more choice?
If you do not need unusual cold performance, waiting—or choosing mature LFP now—can be rational. Early products carry support and resale uncertainty.
