Smart. Sustainable. Sodium. How Eleven's Smart Home Sodium Battery System Works

At Eleven, we’ve designed our home energy system to be smart, safe and sustainable — making it easier than ever for households to switch to clean energy.

Here’s a plain-English breakdown of how it all works:

🔌 𝗛𝘆𝗯𝗿𝗶𝗱 𝗜𝗻𝘃𝗲𝗿𝘁𝗲𝗿 – 𝗧𝗵𝗲 𝗕𝗿𝗮𝗶𝗻𝘀 𝗼𝗳 𝘁𝗵𝗲 𝗢𝗽𝗲𝗿𝗮𝘁𝗶𝗼𝗻

Our hybrid inverter is more than just a converter. It’s the control centre of your home energy system. It efficiently converts solar energy into usable electricity and stores excess in the battery — all while being purpose-built to work with sodium-ion chemistry, which is safer, more sustainable, and better at handling extreme temperatures than lithium.

🔋 𝗦𝗼𝗱𝗶𝘂𝗺 𝗕𝗮𝘁𝘁𝗲𝗿𝘆 𝗣𝗮𝗰𝗸𝘀 – 𝗖𝗹𝗲𝗮𝗻, 𝗘𝘅𝗽𝗮𝗻𝗱𝗮𝗯𝗹𝗲 𝗦𝘁𝗼𝗿𝗮𝗴𝗲

Each battery pack stores 4.5 kWh of energy – enough to power your washing machine, dishwasher, and more. The system is fully modular: start with one pack and scale up to eight as your energy needs grow.

🏡 𝗢𝘂𝘁𝗱𝗼𝗼𝗿-𝗥𝗲𝗮𝗱𝘆 𝗘𝗻𝗰𝗹𝗼𝘀𝘂𝗿𝗲𝘀 – 𝗜𝗻𝘀𝘁𝗮𝗹𝗹 𝗔𝗻𝘆𝘄𝗵𝗲𝗿𝗲

Our IP65-rated enclosures allow for safe installation indoors or out – including garages, sheds, or exterior walls – thanks to the wide temperature tolerance of sodium-ion technology (-20°C to 55°C).

📲 𝗦𝗺𝗮𝗿𝘁 𝗖𝗼𝗻𝘁𝗿𝗼𝗹 𝘄𝗶𝘁𝗵 𝗢𝘂𝗿 𝗘𝗻𝗲𝗿𝗴𝘆 𝗠𝗮𝗻𝗮𝗴𝗲𝗺𝗲𝗻𝘁 𝗦𝘆𝘀𝘁𝗲𝗺 (𝗘𝗠𝗦)

What truly sets Eleven apart is our cloud-connected EMS platform. Designed in-house, it doesn’t just control your battery – it gives your home an energy strategy.
