The purple light strip at the foot of the battery slowly switches on.

Sleep easy, live fully.

The very first battery that combines absolute safety with an unprecedented lifespan. Safe, quiet and built to last.

It stays cool. It does not break. No hassle.

A bright utility room in the evening, with a washing machine, dryer and wooden shelves. On the empty wall hangs Enso, with its soft purple light strip.

The sun is gone. Your power is not.

What your panels make during the day, your battery uses in the evening. Simply, from the garage.

Electricity gets expensive. Yours does not.

Your battery charges during the cheap hours, so you have power during the expensive hours.

Five certainties

That is why you sleep easy with an Enso battery.

Five things you never have to check again.

  1. Certainty 1 · Safe

    Safe indoors, even when it works hard.

    Enso does not get warm. Thanks to the patented salt technology, this is an ultra-safe battery. You forget it is there.

  2. Certainty 2 · Does not break

    It lasts as long as your solar panels.

    You choose once. No replacement date, that is truly sustainable. No new waste pile, no hassle.

  3. At your place
    At your place

    Certainty 3 · Backup

    Outside, the lights go out. Not at your place.

    If the grid drops out, Enso takes over within a few milliseconds. The lights stay on and the fridge stays cold.

  4. Your electricity price with and without Enso

    Certainty 4 · Cheap automatically

    It thinks for you.

    It knows when electricity is cheap and charges then. You follow no tariffs. You only notice it on your bill.

  5. Enso sheltered under a carport, against the outside wall of a house.

    Certainty 5 · Outdoors

    Outdoors works too.

    Want the battery outside? You can. Whether it is high summer or freezing hard, our battery keeps performing safely, reliably and efficiently between −20 °C and +40 °C. So if you would rather have it outside under your carport, no problem (IP55).

The app

Want to take a look? You can.Have to? Never.

Everything runs by itself. If you do want to look, you see at a glance whether your battery is charging and how full it is.

  • What you exchange with the grid and how full it is
  • Notifications and the mode it is running in
  • Self-consumption, timed charging and backup

Enso works best with the Sinexcel Isuna D12K TL inverter, because it is the most compatible with sodium-ion technology. Integration with these brands is also possible:

  • Victron
  • Deye
  • Solis
  • Growatt
  • Schneider Electric
  • SMA
  • Sungrow
  • SOFAR
  • Studer
  • Ingeteam

    You are now using what was saved during the day.
