Support the channel and get extra behind-the-scenes content on Patreon: https://patreon.com/ApexDoma?utm_medi... Eleven Energy has launched a sodium-ion home battery storage system, but is it a serious alternative to lithium battery storage? In this video, Ian visits Solar & Storage Live at the NEC in Birmingham to take a closer look at Eleven Energy and the Galvani battery range. He speaks with Alex from Eleven Energy about how the system works, what makes sodium-ion different from lithium, and why this battery technology could be interesting for UK homes. They cover the Galvani stackable battery system, inverter options, sodium-ion chemistry, sustainability, cold weather performance, battery size, warranties, aftercare, local control, backup options, Shelly integration and whether Eleven Energy could become part of the Apex Doma product range in the future. This is a practical look at a newer battery storage brand that we have had questions about, including the things we like and the areas where we still have questions. If you are comparing home battery storage systems, or wondering whether sodium-ion batteries could be the future, this video is worth watching.
