Energy for the everyday

Wind turbines along a green mountain ridge in soft evening light, with mist in the valleys and a path winding through tea terraces.

Modular batteries for small businesses

Keep the lights on.

ONÉA stores energy on your wall and steps in when the grid drops, so the lights, the till and the fridge can carry on.

Why ONÉA

Your day doesn’t have to stop when the grid does.

A power cut doesn’t wait for a quiet moment. It takes the lights, the card machine and the cold chain at once, and the day stalls.

ONÉA is a quiet system on the wall: modular batteries and one hybrid inverter, designed to keep the essentials of a small business running through the gaps.

Four BLOCK modules, charge settling

BLOCK

Start with one. Stack to four.

Each BLOCK is a 5 kWh module. Begin with one on the wall and add more as the business grows — they all share one CORE.

10kWh

Nominal capacity

Room for refrigeration alongside the essentials.

The everyday interruptions

Three ways the grid gets in the way.

  1. 01

    Unreliable electricity

    Dips and short drops, several times a day. Each one restarts the router, the till and everyone’s patience.

  2. 02

    Power outages

    Hours without the grid, often at the worst moment — at dusk, with customers inside and stock in the fridge.

  3. 03

    Expensive power

    A generator that runs on fuel and noise, and tariffs that keep rising. Stored energy — and the sun — change the arithmetic.

Lights Out

Pick your business. Then cut the power.

An interactive street. Choose a bakery, a pharmacy, a salon or a clinic, switch the grid off, and see what keeps running.

Packages

A system that grows with your needs.

Three example configurations. Each starts with the same CORE; what changes is how much you store.

Two BLOCK and CORE on the tiled wall of a bakery back room.

For a bakery, a salon or a pharmacy with refrigeration.

In the configuration

  • 2 × BLOCK · 10 kWh nominal
  • CORE hybrid inverter
  • Companion app

A scenario

Tuesday, 18:42.

An evening at a neighbourhood bakery. The street goes dark; the display fridge doesn’t.

  1. The grid drops. The street light goes out, then the shop next door.

  2. CORE moves the bakery onto BLOCK. The lights dip for a moment and stay on.

  3. The last loaves sell under the counter lights. The card machine still connects.

  4. The grid returns. BLOCK recharges before the morning bake.

Installers

Built to be installed well.

For electricians and solar installers: one CORE, clear documentation, and modules that hang and lock on a single rail.
