Celtic Sea Three-phase Hybrid Inverter

“We couldn’t be happier with the Eleven Energy inverter and battery system and the support the company has provided. The install was very smooth, the system has worked perfectly since install, the app is great, and the company has been responsive and helpful in updating it.

The sodium-ion battery also provides environmental and technical benefits: it avoids lithium and has a much wider operating temperature than lithium-ion batteries, giving peace of mind for use in our garage.

We highly recommend going for an Eleven Energy system!”

“We have the Eleven sodium battery and inverter with solar panels. We chose this system as we have the peace of mind with a sodium battery that there is no risk of fire, meaning it could be installed safely inside our home.

The system takes up very little space, it is very efficient. The battery charges quickly from the energy generated in the morning from our solar panels. It holds it’s charge and it more than covers our overnight usage.

I can highly recommend the Eleven sodium battery for its performance and reliability.

Also the Eleven app is easy to use. We use it to monitor the batteries state of charge and the solar energy generation, helping us to decide when best to use our appliances more efficiently.”

“I have installed a few Eleven Energy products over the last quarter. The products are very smart, easy to install, and probably the simplest on the market to commission. I expect all installers at some time will have experienced WiFi connection problems and comms or battery voltage issues that can only be sorted out after a long on hold time to technical support. – Not with Eleven Energy.

Customers also like the Sodium battery instead of Lithium.

There is due to be a greater range in products coming soon, I will look to install more!”

“We’ve installed the Eleven Battery sodium system on several projects now, and it’s been a very straightforward experience.

The hardware is well-designed and easy to set up, with a compact footprint and clean integration. The software commissioning process is also smooth – intuitive interface, quick setup, and excellent support from the Eleven team when needed.

From an installer’s point of view, it’s clear that usability and reliability were top priorities in the system design.”

“Our Eleven Energy inverter and battery was installed at the start of the year when we had solar panels fitted. We made a deliberate choice to go with Eleven Energy’s sodium ion battery because of its green credentials. The whole system – panels, battery and inverter – seems to have been highly productive since the day it was switched on, and this is obviously really pleasing to us.

The user-friendly app is great for monitoring performance and even allows us to control when we export to the grid, meaning we can benefit from the higher tariffs offered by our energy supplier (Octopus) when energy demands are greatest. The app shows the accumulated data over the period since the system was switched on, and has clear graphics about the amount we export to the grid, which is useful as a comparison tool with what we see in information provided by Octopus.

We’re new to solar so have appreciated having such a responsive team at Eleven Energy whenever we’ve had questions. We’d not hesitate to recommend them!”
