What is a Volta?

A Volta is a mobile energy system that generates electricity using a combination of solar power, battery storage and a sustainable backup source such as HVO100 or a fuel cell. It is a quiet, clean and flexible alternative to the traditional diesel generator.

More and more construction companies, telecoms providers and local authorities are switching to a Volta.

Why? Because this solution is better suited to today’s challenges: grid congestion, emissions regulations, sustainability targets and permit-free zones such as Natura 2000 areas.

Here, we explain what a Volta is, how it works, why it’s ideal and that it always works, whatever the weather.

How does a Volta work?

A Volta combines multiple energy sources into a single mobile system:

  • Solar panels: Generate sustainable electricity during the day
  • Battery storage: Stores the electricity and supplies it to the user
  • Back-up system: Automatically kicks in when more power is needed.

At Volta Energy, we use smart Victron controls, real-time monitoring (via app or portal) and a compact, robust design that is up and running within an hour.

When should you use a Volta?

Volta units are the solution for temporary power supply at sites where:

  • No fixed mains connection is available.
  • Mains congestion occurs (e.g. new housing estates or construction projects)
  • Permit-free electricity is required (e.g. in nature reserves)
  • Noise and emissions must be kept to a minimum (e.g. city centres, night-time work)

Common applications:

What is the difference compared to a conventional diesel generator?

    With a Volta, you reduce emissions, odours and noise, avoid grid issues and meet strict environmental requirements without compromising on reliability.

Frequently Asked Questions about Volta's

  • Is a Volta more expensive than a conventional diesel generator?
    By the end of the project, this is often not the case. As we charge a single all-inclusive price, we often come in below the total cost of using a conventional diesel generator.
  • Can I use electricity at night when there’s no sun?
    Yes, thanks to the battery and backup system, the system runs 24/7 – even in wet weather and at night.
  • How do I know which model I need?
    Every situation is different, and we’d be happy to work with you to find the right solution.
