Whisper Generator

Looking for a whisper generator? A mobile power solution that runs silently, without the diesel smell and without the constant refuelling? Meet the Volta.

The Volta runs first and foremost on solar energy and battery storage, so on a normal day it needs no fuel and no motor at all. When extra power is needed, a clean backup kicks in automatically and briefly, using HVO100 or methanol instead of diesel. The result: a mobile energy system that stays quiet, clean, and reliable, even when demand spikes.

Why choose the Volta over a standard generator?

A conventional diesel generator runs constantly, whether you need the power or not. The Volta doesn't. Solar and battery cover most of your energy demand, and the backup only activates when it's genuinely needed. On average, that means 60% less fuel use than a standard diesel generator, alongside significantly less noise and no more diesel pollution for your team or neighbours!

Who is it for?

A silent power solution matters most where noise and emissions get noticed: construction sites, telecom infrastructure, renewables projects, traffic control systems, and mobile camera security setups, especially in built-up or environmentally sensitive areas. Your employees and neighbours won't be disturbed by the rattle and smell of a standard generator, and you'll meet the sustainability requirements more and more clients now demand.

Rent your whisper generator, fully managed

We don't sell the Volta. We offer a comprehensive service that includes renting it out, and: delivery, fuel management, maintenance, and remote monitoring, all included in a fixed all-in-one price. No surprises afterwards, no separate maintenance contracts to arrange. You get reliable, quiet power exactly where and when you need it, and we take care of the rest.

Frequently Asked Questions about Whisper Generators

  • What is a whisper generator?
    A whisper generator is a mobile power system designed to run silently, typically by relying on solar and battery power instead of a constantly running diesel engine.
  • How much fuel does a whisper generator like the Volta save?
    On average, the Volta uses 60% less fuel than a conventional diesel generator, saving around €200 per week, because solar and battery cover most of the energy demand.
  • Does a whisper generator still need fuel at all?
    Only occasionally. A clean backup generator running on HVO100 biofuel or methanol activates automatically when solar and battery power aren't enough, and stays off the rest of the time.
  • Is a whisper generator suitable for construction, telecom, or traffic control systems?
    Yes. Whisper generators like the Volta are used across construction sites, telecom infrastructure, renewables projects, traffic control systems, and mobile camera security setups, wherever quiet, reliable power matters.
