Electricity is priced by the hour you need it.

It charges when energy is cheap or your own, and discharges when it’s dear, when the grid fails or the sun sets. From 243 kWh to 6 MWh, built in the Czech Republic.

One day, four ways to save

Storage moves energy in time. Pick what it should do.

Peak shaving

You’re billed by your highest 15-minute peak. Storage covers the peaks, so you reserve less. It recharges at night.

One system, six jobs

Its control switches between jobs, depending on what pays more at the time.

  • Peak shaving

    Lower reserved capacity, no overrun penalties.

  • Time shifting

    Buy cheap, release dear.

  • Solar self-consumption

    Use your midday surplus in the evening.

  • Backup and island mode

    Switchover within 6 ms; the site keeps running.

  • Ancillary services

    Flexibility for the grid as FCR and aFRR. Standby earns money.

  • Electrification without a bigger connection

    EV chargers and heat pumps without a grid upgrade.

Built to last decades, not a season

European components, designed and built in the Czech Republic. Each module also works on its own.

Rent, lease or buy

Try it first. The rent you pay isn’t lost.

  • Rent

    For a period you choose. A flat fee by length and number of cycles. Buy later and the rent counts towards the price.

    For events, outages and pilot projects
  • Lease

    You pay from the savings; the storage stays ours. It barely touches cash flow.

    For towns, companies without spare capital and grant-funded projects
  • Buy

    All savings and revenue are yours. We help with grants and connection.

    For long-term operation with the highest return

Questions we get asked

How big does my storage need to be?

It depends on the job. For peak shaving, power in kW is what matters; for shifting energy in time, capacity in kWh. We size it from your 15-minute demand data for the past 12 months.

Does it work outdoors in winter?

Yes, down to −25 °C and with no heating. Waste heat from its own liquid-cooled inverters keeps the batteries warm.

Is battery storage safe?

We use automotive-grade battery modules and certified European components. The coolant contains fire-suppressing additives, and the system has integrated fire suppression and continuous online monitoring. Each module works on its own, which raises the reliability and safety of the whole system.

Can it keep my site running without the grid?

Yes. During an outage it takes over within 6 ms. How long the site lasts depends on capacity and consumption. With solar or CHP, it can run on its own for extended periods.

Can I try storage first?

Yes, by renting. If you then decide to buy, all the rent you have paid counts towards the purchase price.

Are there grants for storage?

Often, yes. In the Czech Republic, calls for energy storage open regularly, for example under the Modernisation Fund. We help you choose a programme and prepare the application.
